CompTIA SY0-701 Dumps

A regulatory requirement is a mandate imposed by a government or an authority that must be followed by an organization or an individual. In a banking environment, audits are often required by regulators to ensure compliance with laws, standards, and policies related to security, privacy, and financial reporting. Audits help to identify and correct any gaps or weaknesses in the security posture and the internal controls of the organization.

A self-signed certificate is generated internally without involving an external Certificate Authority (CA). In a self-signed certificate, the certificate issuer and certificate subject are the same entity. Security+ SY0-701 explains that organizations frequently use self-signed certificates for internal systems, lab environments, or testing scenarios where external trust chains are unnecessary.

A digital signature (A) is a cryptographic function, not a certificate. Asymmetric keys (B) are used in public-key cryptography but do not constitute a certificate by themselves. Symmetric keys (D) are encryption tools, not certificates.

Therefore, the example of a certificate generated internally is C: Self-signed.

Aprocedureprovides step-by-step instructions on how to complete a specific security task, ensuring consistency and accuracy. Unlike policies, which define high-level security expectations,procedures are detailed and operational. For example, apassword reset procedurewould outline the exact steps IT support must follow when assisting users.

Policy: Defines security objectives and rules (e.g., "All passwords must be complex").

Standard: Specifies required technologies or configurations.

Guideline: Provides recommendations but is not mandatory.

Procedure: Gives exact instructions to perform tasks.

The correct answer is Accept because knowingly choosing not to address identified vulnerabilities is a formal example of risk acceptance. In the Security+ SY0-701 risk management framework, accepting risk means that leadership is aware of a vulnerability and its potential impact but decides to take no corrective action. This decision is typically based on factors such as cost, operational constraints, low likelihood of exploitation, or limited business impact.

Risk acceptance is a deliberate management decision, not an oversight. When a Chief Information Security Officer ignores known vulnerabilities identified during a risk assessment, the organization is implicitly acknowledging the risk and choosing to tolerate it. The SY0-701 study guide emphasizes that risk acceptance must be informed and approved by appropriate leadership, as accountability remains with the organization if the risk materializes.

Option A, Transfer, is incorrect because transferring risk involves shifting responsibility to a third party, such as purchasing cyber insurance or outsourcing services. Option B, Avoid, refers to eliminating risk entirely by discontinuing the risky activity, system, or process. Option C, Mitigate, involves implementing security controls to reduce the likelihood or impact of the risk, such as patching vulnerabilities or adding compensating controls.

Accepting risk does not mean the vulnerability is harmless; it means leadership has determined that addressing it is not justified at that time. The SY0-701 objectives highlight that accepted risks should be documented, reviewed periodically, and reassessed as conditions change, especially if threat likelihood or business impact increases.

In summary, ignoring known vulnerabilities after a risk assessment reflects a conscious decision to tolerate potential loss rather than reduce or eliminate it. This aligns directly with the risk acceptance strategy, making Option D the correct answer.

A directive managerial control provides guidance and expectations for behavior through policy and governance. An Acceptable Use Policy (AUP) is a classic example, as it defines how users may and may not use organizational systems and data. Security+ SY0-701 categorizes policies as managerial (administrative) controls that direct user behavior and establish accountability.

A login warning banner (B) is typically a deterrent/administrative control but is not managerial in nature. A master service agreement (C) is a contractual/legal document, not a managerial directive for internal users. A “No trespassing” sign (D) is a physical deterrent control.

Because an AUP formally directs behavior and is enforced through management processes, A: Acceptable use policy is correct.

Detailed Explanation:The Common Vulnerability Scoring System (CVSS) is a standardized metric used to assess the severity of vulnerabilities, aiding organizations in prioritizing their response based on risk. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Vulnerabilities, Section: "Vulnerability Prioritization and Metrics"​​.

Comprehensive and Detailed In-Depth Explanation:

User awareness training is essential in preventing security incidents caused by human error, such as clicking on malicious links. Employees need to be educated on recognizing phishing attempts, verifying email senders, and avoiding suspicious downloads.

Network monitoringdetects and alerts on malicious activity but does not prevent employees from clicking on harmful links.

Endpoint protectioncan mitigate malware infections but is not foolproof, especially if users continue to fall for phishing attacks.

Data loss prevention (DLP)can prevent data exfiltration but does not stop malware from being introduced into the system.

By training employees to recognize and avoid phishing scams, organizations canreduce the risk of malware infections and data breaches.

The lessons learned phase of an incident response process involves reviewing the incident and generating reports. This phase helps identify what went well, what needs improvement, and what changes should be made to prevent future incidents. Documentation and reporting are essential parts of this phase to ensure that the findings are recorded and used for future planning.

Recovery focuses on restoring services and normal operations.

Preparation involves creating plans and policies for potential incidents, not reporting.

Containment deals with isolating and mitigating the effects of the incident, not generating reports​​.

This is a classic example of Business Email Compromise (BEC), where attackers spoof or compromise trusted email accounts to trick employees into performing unauthorized financial transactions.

Vishing (B) is voice phishing, spear phishing (C) targets individuals with customized messages, and impersonation (D) is a general term for identity deception but BEC specifically describes financial fraud via email.

BEC is a major threat covered in the Threats domain of SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】

Salting is the process of adding extra random data to a password or other data before applying a one-way data transformation algorithm, such as a hash function. Salting increases the complexity and randomness of the input data, making it harder for attackers to guess or crack the original data using precomputed tables or brute force methods. Salting also helps prevent identicalpasswords from producing identical hash values, which could reveal the passwords to attackers who have access to the hashed data. Salting is commonly used to protect passwords stored in databases or transmitted over networks. References =

A watering-hole attack is a type of cyberattack that targets groups of users by infecting websites that they commonly visit. The attackers exploit vulnerabilities to deliver a malicious payload to the organization’s network. The attack aims to infect users’ computers and gain access to a connected corporate network. The attackers target websites known to be popular among members of a particular organization or demographic. The attack differs from phishing and spear-phishing attacks, which typically attempt to steal data or install malware onto users’ devices1

In this scenario, the compromised industry blog is the watering hole that the attackers used to spread malware across the company’s network. The attackers likely chose this blog because they knew that the employees of the company were interested in its content and visited it frequently. The attackers may have injected malicious code into the blog or redirected the visitors to a spoofed website that hosted the malware. The malware then infected the employees’ computers and propagated to the network.

References1: Watering Hole Attacks: Stages, Examples, Risk Factors & Defense …

Detailed Explanation:

Sanctions imposed for non-compliance can include fines, legal actions, and loss of business licenses. These pose a significant financial and reputational risk to organizations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Regulatory Compliance Risks"​​.

A dashboard is a graphical user interface that provides a visual representation of key performance indicators, metrics, and trends related to security events and incidents. A dashboard can help the board of directors to understand the number and impact of incidents that affected the organization in a given period, as well as the status and effectiveness of the security controls and processes. A dashboard can also allow the board of directors to drill down into specific details or filter the data by various criteria12.

A packet capture is a method of capturing and analyzing the network traffic that passes through a device or a network segment. A packet capture can provide detailed information about the source, destination, protocol, and content of each packet, but it is not a suitable way to present a summary of incidents to the board of directors13.

A vulnerability scan is a process of identifying and assessing the weaknesses and exposures in a system or a network that could be exploited by attackers. A vulnerability scan can help the organization to prioritize and remediate the risks and improve the security posture, but it is not a relevant way to report the number of incidents that occurred in a quarter14.

Metadata is data that describes other data, such as its format, origin, structure, or context. Metadata can provide useful information about the characteristics and properties of data, but it is not a meaningful way to communicate the impact and frequency of incidents to the board of directors. References = 1: CompTIA Security+ SY0-701 Certification Study Guide, page 3722: SIEM Dashboards – SY0-601 CompTIA Security+ : 4.3, video by Professor Messer3: CompTIA Security+ SY0-701 Certification Study Guide, page 3464: CompTIA Security+ SY0-701 Certification Study Guide, page 362. : CompTIA Security+ SY0-701 Certification Study Guide, page 97.

 An ISOW is a document that outlines the project, the cost, and the completion time frame for a security company to provide a service to a client. ISOW stands for Information Security Operations Work, and it is a type of contract that specifies the scope, deliverables, milestones, and payment terms of a security project. An ISOW is usually used for one-time or short-term projects that have a clear and defined objective and outcome. For example, an ISOW can be used for a security assessment, a penetration test, a security audit, or a security training.

The other options are not correct because they are not documents that outline the project, the cost, and the completion time frame for a security company to provide a service to a client. A MSA is a master service agreement, which is a type of contract that establishes the general terms and conditions for a long-term or ongoing relationship between a security company and a client. A MSA does not specify the details of each individual project, but rather sets the framework for future projects that will be governed by separate statements of work (SOWs). A SLA is a servicelevel agreement, which is a type of contract that defines the quality and performance standards for a security service provided by a security company to a client. A SLA usually includes the metrics, targets, responsibilities, and penalties for measuring and ensuring the service level. A BPA is a business partnership agreement, which is a type of contract that establishes the roles and expectations for a strategic alliance between two or more security companies that collaborate to provide a joint service to a client. A BPA usually covers the objectives, benefits, risks, and obligations of the partnership. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 387. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.2: Compliance and Controls, video: Contracts and Agreements (5:12).

Detailed Explanation:An unskilled attacker, often referred to as a script kiddie, is likely to engage in website defacement. This type of attack typically requires minimal expertise and is often conducted for notoriety. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Threats, Section: "Threat Actors and Motivations"​​.

Typosquatting is a social engineering and cybersquatting technique in which attackers register domain names similar to legitimate ones, hoping users will make a typographical error and visit their malicious website instead.

Detailed Explanation:Mean Time to Repair (MTTR) is a key metric in risk management, reflecting the time required to repair a failed component, such as a generator, and restore operations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Business Continuity Metrics"​​.

Containment (C)is thefirst critical stepduring a security incident tostop the spreadof the attack. This could include isolating affected systems, disabling accounts, or blocking malicious traffic.

According to theIncident Response Lifecycle, the order is typically:Identification → Containment → Eradication → Recovery → Lessons Learned.

Baseline configuration is the process of standardizing the configuration settings for a system or network. In this scenario, the organization needs to standardize the operating system configurations before deploying them across the network. Establishing a baseline configuration ensures that all systems adhere to the organization's security policies and operational requirements.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of system hardening and configuration management​​.

A tabletop exercise is a discussion-based simulation where incident response (IR) team members walk through hypothetical security scenarios to understand roles, responsibilities, escalation paths, and communication processes. According to Security+ SY0-701, tabletop exercises are ideal for familiarizing participants with the incident response process and improving organizational readiness without the pressure or resource demands of full-scale simulations.

These exercises highlight:

IR workflow clarity

Decision-making processes

Coordination between technical and non-technical teams

Communication procedures

Identification of gaps in policies or documentation

Option B (rules of engagement) is part of penetration testing planning, not tabletop exercises. Option C refers to real breach analysis, not simulations. Option D refers to forensic operations, not tabletop objectives.

Thus, A is correct.

SASE stands for Secure Access Service Edge. It is a cloud-based service that combines network and security functions into a single integrated solution. SASE can help reduce traffic on the VPN and internet circuit by providing secure and optimized access to the data center and cloud applications for remote employees. SASE can also monitor and enforce security policies on the remote employee internet traffic, regardless of their location or device. SASE can offer benefits such as lower costs, improved performance, scalability, and flexibility compared to traditional VPN solutions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457-458 1

Detailed Explanation:Privileged access management (PAM) solutions effectively mitigate pass-the-hash attacks by enforcing least privilege and session management for administrative accounts. These tools restrict how and when credentials can be accessed, thereby reducing attack surfaces. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Vulnerabilities, Section: "Mitigation Techniques"​​.

Firmware is a type of software that is embedded in a hardware device, such as a router, a printer, or a BIOS chip. Firmware controls the basic functions and operations of the device, and it can be updated or modified by the manufacturer or the user. Firmware version is a hardware-specific vulnerability, as it can expose the device to security risks if it is outdated, corrupted, or tampered with. An attacker can exploit firmware vulnerabilities to gain unauthorized access, modify device settings, install malware, or cause damage to the device or the network. Therefore, it is important to keep firmware updated and verify its integrity and authenticity. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 67. CompTIA Security+ SY0-701 Exam Objectives, Domain 2.1, page 10.

Social engineering is the practice of manipulating people into performing actions or divulging confidential information, often by impersonating someone else or creating a sense of urgency or trust. The suspicious caller in this scenario was trying to use social engineering to trick the user into giving away credit card information by pretending to be the CFO and asking for a payment. The user recognized this as a potential scam and reported it to the IT help desk. The other topics are not relevant to this situation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 19 1

A red team is a group of security professionals who perform offensive security assessments covering penetration testing and social engineering. A red team simulates real-world attacks and exploits the vulnerabilities of a target organization, system, or network. A red team aims to test the effectiveness of the security controls, policies, and procedures of the target, as well as the awareness and response of the staff and the blue team. A red team can be hired as an external consultant or formed internally within the organization. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 18.

Software as a Service (SaaS) is the cloud model that best meets the goal of outsourcing the management, including patching, of firmware, operating systems, and applications to the cloud vendor. In a SaaS environment, the cloud provider is responsible for maintaining and updating the entire software stack, allowing the organization to focus on using the software rather than managing its infrastructure.

References = CompTIA Security+ SY0-701 study materials, particularly the domains related to cloud security models​​.

Compensating controls are alternative security measures that are implemented when the primary controls are not feasible, cost-effective, or sufficient to mitigate the risk. In this case, the organization used compensating controls to protect the legacy system from potential attacks by disabling unneeded services and placing a firewall in front of it. This reduced the attack surface and the likelihood of exploitation.

Container image hardening best practices include removing default or unnecessary applications (A) to reduce the attack surface and disabling insecure protocols like Telnet (C) to prevent exploitation. Minimizing software components reduces vulnerabilities and limits potential exploits.

Installing a Network Intrusion Prevention System (NIPS) (B) is a network security measure, not typically embedded in a container image. Reconfiguring DNS (D), adding an SFTP server (E), or deleting public certificates (F) are unrelated or could disrupt container functionality.

These practices are part of securing containerized environments covered under Security Architecture topics in SY0-701【6:Chapter 10†CompTIA Security+ Study Guide】.

Bug bounty programs invite vetted external researchers to report software vulnerabilities in exchange for rewards. According to Security+ SY0-701, two major benefits are:

(1) Reduction in the number of zero-day vulnerabilities (B) – Ethical hackers can discover unknown vulnerabilities before malicious attackers do. These vulnerabilities are often zero-days because they are unknown to vendors at the time of discovery. Bug bounty programs surface these issues early, helping organizations mitigate severe risks proactively.

(2) Quicker discovery of vulnerabilities (E) – A distributed network of global security researchers can identify vulnerabilities far faster than an internal team alone. This accelerates detection, increases coverage, and lowers attacker dwell time.

Option A (Transference of risk) is incorrect because bug bounties do not transfer risk—they help identify vulnerabilities. C (Security awareness) relates to internal training, not bug bounties. D (Reduced cost) is misleading; bug bounties can be expensive depending on payout structure. F (Patch management) does not directly improve through bug bounty programs.

Therefore, the correct benefits are B and E.

A third-party audit provides an independent assessment of the SaaS vendor’s security controls, compliance, and practices. This documentation helps verify that the vendor meets security standards and follows best practices.

Secure Access Service Edge (SASE) is the technology best suited for preventing remote users from accessing malicious URLs. According to the CompTIA Security+ SY0-701 framework, SASE integrates cloud-native security capabilities such as DNS filtering, secure web gateways, CASB, and URL categorization, all delivered inline. This means every URL request from a remote user is checked in real time for reputation, content, and category before access is granted.

This solution is specifically designed for remote workforces because security enforcement happens in the cloud, regardless of user location—eliminating reliance on on-premise proxies or VPN routing. SASE also enables consistent policy application and real-time enforcement across distributed networks.

A VPN (A) only encrypts traffic; it does not perform URL reputation checks. IDS (C) detects malicious activity but does not block URL access. SD-WAN (D) optimizes WAN routing but is not focused on content filtering or URL reputation.

Therefore, SASE is the correct and most effective solution for inline URL inspection and preventing remote users from reaching malicious sites.

The company should request a certification from the vendor that confirms the storage array has been disposed of securely and in compliance with the company’s policies and standards. A certification provides evidence that the vendor has followed the proper procedures and methods to destroy the classified data and prevent unauthorized access or recovery. A certification may also include details such as the date, time, location, and method of disposal, as well as the names and signatures of the personnel involved. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3, page 1441

When investigating abnormal outbound traffic originating from a specific endpoint, endpoint logs are the most appropriate first data source to review. According to CompTIA Security+ SY0-701, endpoint logs provide detailed visibility into process execution, user actions, service creation, network connections initiated by applications, and security agent detections. This context is critical for determining which process initiated the encrypted traffic and why it is using non-standard ports.

Because the traffic is encrypted, packet captures (D) would reveal limited payload information and are more resource-intensive. Endpoint logs can quickly identify suspicious executables, command-line arguments, parent-child process relationships, and persistence mechanisms that indicate malware or command-and-control activity. Modern EDR tools rely heavily on endpoint telemetry for exactly this reason.

Application logs (A) may be useful later but are limited to specific applications. Vulnerability scans (B) identify weaknesses, not active malicious behavior.

Security+ SY0-701 emphasizes starting investigations as close to the suspected source as possible. Since the activity originates from a corporate endpoint, endpoint logs provide the fastest and most relevant confirmation of whether the traffic is malicious.

To reduce risky behaviors such as clicking suspicious emails, the first and most effective step is to implement a phishing awareness campaign that educates users about recognizing phishing attempts, the risks involved, and safe practices. Awareness training can significantly reduce successful phishing attacks by changing user behavior.

Updating policies (A) is important but does not directly affect user behavior immediately. Password management solutions (B) help with credential security but do not reduce phishing click rates. Issuing warning letters (C) is punitive and less effective than proactive education.

This approach aligns with Security Program Management principles emphasizing training and awareness as primary controls against phishing risks【6:Chapter 16†CompTIA Security+ Study Guide】.

Non-compliance with internal policies, such as corporate security policies, falls under internal non-compliance. These are rules created and enforced within the organization to maintain security standards.

External non-compliance (A) refers to violations of outside regulations or laws. Standards (B) are generally established best practices or industry guidelines, and regulation (C) refers to legal or governmental requirements.

Internal compliance management is a key focus area in the Security Program Management domain of SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

An insider threat is a type of attack that originates from someone who has legitimate access to an organization’s network, systems, or data. In this case, the domain user who encrypted the files on the database server is an example of an insider threat, as they abused their access privileges to cause harm to the organization. Insider threats can be motivated by various factors, such as financial gain, revenge, espionage, or sabotage.

A supply chain vendor is a third-party entity that provides goods or services to an organization, such as a SaaS provider. A supply chain vendor can pose a risk to the new system if the vendor has poor security practices, breaches, or compromises that could affect the confidentiality, integrity, or availability of the system or its data. The organization should perform due diligence and establish a service level agreement with the vendor to mitigate this risk. The other options are not specific to the scenario of using a SaaS provider, but rather general risks that could apply to any system.

Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into a website, which are then executed in the user’s web browser, potentially leading to data theft or session hijacking.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.

Organizational risk tolerance is the primary factor determining how quickly and aggressively vulnerabilities should be remediated. Security+ SY0-701 explains that organizations have different appetites for risk depending on business needs, regulatory expectations, operational constraints, and financial impact.

A company with low risk tolerance may prioritize almost every vulnerability and remediate quickly.

A company with high risk tolerance may delay or accept some lower-impact risks.

This consideration directly influences patch prioritization, resource allocation, and mitigation timelines.

Option A—executive reporting—does not influence technical prioritization.

Option C—open-source intelligence—helps identify vulnerabilities but does not determine urgency.

Option D—the source of the reported risk—is irrelevant; what matters is severity and business impact.

Thus, B: The overall organizational risk tolerance is the key factor for prioritizing remediation.

Alerts generated by SIEM (Security Information and Event Management) tools are detective controls, as they identify and notify about suspicious activities but do not prevent or correct the events themselves.

Preventive controls stop incidents before they occur, corrective controls remediate issues, and compensating controls are alternatives used when primary controls aren’t feasible.

Detective controls are foundational in Security Operations for incident detection and response【6:Chapter 14†CompTIA Security+ Study Guide】.

Detailed Explanation:Load balancing improves application availability by distributing traffic across multiple servers. If one server fails, traffic is automatically routed to other available servers with minimal intervention. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "High Availability Solutions"​​.

AnAPI (B)or Application Programming Interface is the best option when you want toautomate data exchangebetween systems. APIs provide structured, secure, and efficient ways for systems to communicate and are widely used in automation and orchestration tasks.

SOAR (A)is used for broader security orchestration and may use APIs under the hood but is more complex.

SFTP (C)is for manual/automated file transfers.

RDP (D)is for remote desktop access, not data automation.

This is referenced inDomain 1.5: Explain the importance of automation and orchestration in cybersecurityunder“Application programming interfaces (APIs).”

According to the shared responsibility model, the client and the cloud provider have different roles and responsibilities for securing the cloud environment, depending on the service model. In an IaaS (Infrastructure as a Service) model, the cloud provider is responsible for securing the physical infrastructure, such as the servers, storage, and network devices, while the client is responsible for securing the operating systems, applications, and data that run on the cloud infrastructure. Therefore, the client is responsible for securing the company’s database in an IaaS model for a cloud environment, as the database is an application that stores data. The client can use various security controls, such as encryption, access control, backup, and auditing, to protect the database from unauthorized access, modification, or loss. The third-party vendor and the DBA (Database Administrator) are not roles defined by the shared responsibility model, but they may be involved in the implementation or management of the database security. References = CompTIA Security+ SY0-701 Certification Study Guide, page 263-264; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 3.1 - Cloud and Virtualization, 5:00 - 7:40.

A security awareness program is a set of activities and initiatives that aim to educate and inform the users and employees of an organization about the security policies, procedures, and best practices. A security awareness program can help to reduce the human factor in security risks, such as social engineering, phishing, malware, data breaches, and insider threats. A security awareness program should include various elements of communication, such as newsletters, posters, videos, webinars, quizzes, games, simulations, and feedback mechanisms, to deliver the security messages and reinforce the security culture. One of the most likely elements of communication to be included in a security awareness program is reporting phishing attempts or other suspicious activities, as this can help to raise the awareness of the users and employees about the common types of cyberattacks and how to respond to them. Reporting phishing attempts or other suspicious activities can also help to alert the security team and enable them to take appropriate actions to prevent or mitigate the impact of the attacks. Therefore, this is the best answer among the given options.

The other options are not as likely to be included as elements of communication in a security awareness program, because they are either technical or operational tasks that are not directly related to the security awareness of the users and employees. Detecting insider threats using anomalous behavior recognition is a technical task that involves using security tools or systems to monitor and analyze the activities and behaviors of the users and employees and identify any deviations or anomalies that may indicate malicious or unauthorized actions. This task is usually performed by the security team or the security operations center, and it does not require the communication or participation of the users and employees. Verifying information when modifying wire transfer data is an operational task that involves using verification methods, such as phone calls, emails, or digital signatures, to confirm the authenticity and accuracy of the information related to wire transfers, such as the account number, the amount, or the recipient. This task is usually performed by the financial or accounting department, and it does not involve the security awareness of the users and employees. Performing social engineering as part of third-party penetration testing is a technical task that involves using deception or manipulation techniques, such as phishing, vishing, or impersonation, to test the security posture and the vulnerability of the users and employees to social engineering attacks. This task is usuallyperformed by external security professionals or consultants, and it does not require the communication or consent of the users and employees. Therefore, these options are not the best answer for this question. References = Security Awareness and Training – CompTIA Security+ SY0-701: 5.2, video at 0:00; CompTIA Security+ SY0-701 Certification Study Guide, page 263.

The scenario described, where client files are only accessible to employees who "need to know" the information, reflects the concept of confidentiality. Confidentiality ensures that sensitive information is only accessible to those who are authorized to view it, preventing unauthorized access.

Availability ensures that data is accessible when needed but doesn’t focus on restricting access.

Integrity ensures that data remains accurate and unaltered but doesn’t pertain to access control.

Non-repudiation ensures that actions cannot be denied after they are performed, but this concept is unrelated to access control​​.

Shadow IT refers to software, hardware, cloud services, or applications deployed without approval from the IT or security department. In this scenario, a high school department is using an unvetted simulation program—classic Shadow IT behavior.

Security+ SY0-701 explains that Shadow IT:

Introduces unknown vulnerabilities

Bypasses security controls

Creates compliance risks

Leads to data exposure

Interferes with standard configuration management

Espionage (A) involves intelligence gathering, not unauthorized software use. Data exfiltration (B) involves data theft, not unauthorized software deployment. Zero-day (D) refers to unknown vulnerabilities, not unapproved systems.

Thus, Shadow IT is the correct answer.

A Virtual Private Network (VPN) is the best solution to allow remote employees secure access to company resources without interception concerns. A VPN establishes an encrypted tunnel over the internet, ensuring that data transferred between remote employees and the company is secure from eavesdropping.

Proxy server helps with web content filtering and anonymization but does not provide encrypted access.

NGFW (Next-Generation Firewall) enhances security but is not the primary tool for enabling remote access.

Security zone is a network segmentation technique but does not provide remote access capabilities​​​.

Serverless architecture allows companies to deploy code without managing the underlying infrastructure. This approach significantly reduces the time and expense involved in code deployment because developers can focus solely on writing code, while the cloud provider manages the servers, scaling, and maintenance. Serverless computing also enables automatic scaling and pay-per-execution billing, which further optimizes costs.

References =

CompTIA Security+ SY0-701 Course Content: The course covers cloud technologies, including serverless architectures, which are highlighted as a method to streamline and reduce costs associated with code deployment​​​.

When multiple Wireless Access Points (WAPs) are using similar frequencies with high power settings, it can cause channel overlap, leading to interference and connectivity issues. This is likely the reason why mobile users are unable to access the internet in the lobby. Evaluating and adjusting the channel settings on the WAPs to avoid overlap is crucial to resolving the connectivity problems.

References = CompTIA Security+ SY0-701 study materials, particularly the domain on Wireless and Mobile Security, which covers WLAN deployment considerations​​.

Port security is the best mitigation technique for preventing an attacker from flooding the MAC address table of network switches. Port security can limit the number of MAC addresses learned on a port, preventing an attacker from overwhelming the switch's MAC table (a form of MAC flooding attack). When the allowed number of MAC addresses is exceeded, port security can block additional devices or trigger alerts.

Load balancer distributes network traffic but does not address MAC flooding attacks.

IPS (Intrusion Prevention System) detects and prevents attacks but isn't specifically designed for MAC flooding mitigation.

NGFW (Next-Generation Firewall) offers advanced traffic inspection but is not directly involved in MAC table security​​​.

Data masking replaces sensitive data with realistic but fictional data, preserving format and usability while protecting confidential information during testing in environments like UAT (User Acceptance Testing).

Tokenization (B) replaces data with tokens but is more common for payment data in production. Obfuscation (C) scrambles data but is less structured than masking. Encryption (D) protects data confidentiality but may not be practical for testing.

Data masking is a best practice for protecting sensitive data in non-production environments covered in the General Security Concepts domain【6:Chapter 7†CompTIA Security+ Study Guide】.

Data classification is the process of assigning labels or tags to data based on its sensitivity, value, and risk. Data classification is the first step in a data loss prevention (DLP) solution, as it helps to identify what data needs to be protected and how. By applying classifications to the data, the security administrator can define appropriate policies and rules for the DLP solution to prevent the exfiltration of sensitive customer data. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 8: Data Protection, page 323. CompTIA Security+ Practice Tests: Exam SY0-701, 3rd Edition, Chapter 8: Data Protection, page 327.

SOAR (Security Orchestration, Automation, and Response) is designed to automate repetitive security tasks, orchestrate workflows, and reduce manual effort in identifying and containing threats. CompTIA Security+ SY0-701 describes SOAR as an advanced tool that integrates with SIEM, EDR, firewalls, and ticketing systems to automate detection, enrichment, and response actions.

By using SOAR playbooks, security teams can automate:

Initial threat triage

Log correlation

Host isolation

Indicator lookups

Ticket creation and escalation

This significantly reduces the number of manual steps an analyst must perform, achieving the manager’s goal of streamlining threat-handling procedures.

A SIEM (B) centralizes logs and alerts but still requires manual investigation unless paired with SOAR. DMARC (C) protects email domains from spoofing but does not automate threat response. NIDS (D) detects threats on the network but does not automate containment.

SOAR’s ability to automate identification and response makes A the correct answer.

When hosting an on-premises software application in a cloud-based service, ensuring visualization and isolation of resources is crucial for maintaining security best practices. This involves using virtualization techniques to create isolated environments (e.g., virtual machines or containers) for different applications and services, reducing the risk of cross-tenant attacks or resource leakage.

Network segmentation is important but pertains more to securing network traffic rather than isolating computing resources.

Data encryption is also essential but doesn’t specifically address resource isolation in a cloud environment.

Strong authentication policies are critical for access control but do not address the need for isolating resources within the cloud environment​​.

A Security Information and Event Management (SIEM) solution collects, aggregates, and correlates logs from multiple sources to detect anomalies and generate alerts. SIEMs are essential for security monitoring and incident detection.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.

Memory injectionoccurs whenmalicious code is written into the memory space of a running process, allowing it to execute without writing anything to disk. This is often used infileless malware attacks, making detection harder.

A (privilege escalation)describes a race condition, not memory injection.

B (unexpected data causing execution)describes abuffer overflow attack, not memory injection.

D (overwriting an executable)is apersistence technique, but it is not an example of in-memory injection.

Detailed Explanation:Firewall logs provide details of all network traffic, including connections to and from IoT devices. They are typically the first source of evidence for identifying the time of an exploit. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Log Analysis for Incident Response"​​.

Comprehensive and Detailed Explanation From Exact Extract:

A responsibility matrix, often referred to in cloud computing as the Shared Responsibility Model, defines the exact roles, duties, and expectations between a cloud service provider (CSP) and the customer. This includes who is responsible for configuration, maintenance, patching, logging, updates, identity management, network security, and data protection.

According to the SY0-701 exam objectives, cloud models such as SaaS, PaaS, and IaaS all divide responsibilities differently. The responsibility matrix clarifies these boundaries so that neither party assumes the other is handling a critical security task. Misunderstandings in these areas can create dangerous security gaps, such as unpatched virtual machines, misconfigured storage buckets, or weak access controls.

A Service-Level Agreement (A) focuses on uptime, performance, and service expectations—not shared security roles. A Memorandum of Understanding (C) describes high-level cooperation between organizations, while an NDA (D) protects confidential information.

The responsibility matrix is emphasized under Security Program Management, specifically in managing third-party relationships and cloud provider governance, ensuring both parties understand their obligations and reducing the risk of misconfigurations or operational vulnerabilities.

 Analysis is the incident response activity that describes the process of understanding the source of an incident. Analysis involves collecting and examining evidence, identifying the root cause, determining the scope and impact, and assessing the threat actor’s motives and capabilities. Analysis helps the incident response team to formulate an appropriate response strategy, as well as to prevent or mitigate future incidents. Analysis is usually performed after detection and before containment, eradication, recovery, and lessons learned. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 6, page 223. CompTIA Security+ SY0-701 Exam Objectives, Domain 4.2, page 13.

A hash is an algorithm used to verify data integrity by generating a fixed-size string of characters from input data. If even a single bit of the input data changes, the hash value will change, allowing users to detect any modification to the data. Hashing algorithms like SHA-256 and MD5 are commonly used to ensure data has not been altered.

Detailed Explanation:A Memorandum of Agreement (MOA) outlines terms of cooperation, including restrictions on sharing intellectual property. A breach indicates the terms of the agreement were violated, compromising confidentiality or usage terms. Reference: CompTIASecurity+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Third-Party Risk Management"​​.

Tokenization replaces sensitive financial data—such as credit card numbers, account numbers, or customer identifiers—with harmless tokens that retain usability but reveal nothing if leaked. This is widely used in the financial industry, particularly in PCI-DSS-regulated systems.

Hashing (B) is one-way and not reversible, making it unsuitable for financial transactions that need original data retrieved. Salting (C) is used to protect hashed passwords, not to mask financial data. Steganography (D) hides data inside media files but is not used for payment processing.

Security+ SY0-701 identifies tokenization as the preferred method for protecting structured sensitive data while maintaining operational functionality.

Thus, the correct answer is A: Tokenization.

Comprehensive and Detailed In-Depth Explanation:

Aload balancerdistributes incoming traffic evenly across multiple servers to prevent any single server from becoming overloaded. This ensureshigh availability, scalability, and optimal performanceof the company's website.

Server multiprocessing (A)refers to the use of multiple processors within a single server but does not distribute traffic across multiple servers.

A warm site (B)is a disaster recovery strategy, not a method for balancing real-time traffic.

A proxy server (D)acts as an intermediary between users and web services but does not distribute server load.

Using aload balancerallows forefficient traffic management and prevents server overload.

A false positive is an alert that incorrectly identifies benign activity as malicious. Over time, if an alerting system generates too many false positives, security teams are likely to ignore these alerts, resulting in "alert fatigue." This increases the risk of missing genuine threats.

True positives and true negatives are accurate and should be acted upon.

False negatives are more dangerous because they fail to identify real threats, but they are not "ignored" since they do not trigger alerts​​.

Impossible travel (A)refers to logins fromgeographically distant locations within a time period that makes travel between them physically impossible. In this case, a user logging in fromChicago and Rome within a short timeframetriggers this anomaly.

This is a strong indicator of acompromised accountorstolen credentialsbeing used elsewhere.

An image backup, also known as a full system backup, captures the entire contents of a system, including the operating system, applications, settings, and all data. This type of backup allows for a complete recovery of the system in case of a disaster, as it includes everything needed to restore the system to its previous state. This makes it the ideal choice for a systems administrator who needs to ensure the ability to recover the entire system, including the OS.

Applying the latest OS updates, patches, and endpoint definitions is the most effective way to prevent known exploits, which are attacks leveraging previously discovered vulnerabilities for which fixes are available.

AMaster Service Agreement (MSA)establishesthe general terms and conditionsfor ongoing business engagements. This allows companies toreuse the same termsacross multiple contracts, revisiting them periodically for updates.

NDA (B)protects confidential information but does not define service terms.

MOU (C)is a non-binding agreement, often used for partnerships, not formal service contracts.

SLA (D)focuses onservice performance expectations, not overall contract terms.

A vulnerability scan is the most effective method for identifying legacy systems within an environment. Vulnerability scanners assess hosts for outdated operating systems, unsupported software versions, missing patches, deprecated services, and known Common Vulnerabilities and Exposures (CVEs). CompTIA Security+ SY0-701 highlights vulnerability scanning as a foundational security operation used to gain visibility into system age, patch status, and configuration weaknesses.

Legacy systems often stand out in scan results because they run end-of-life operating systems, use deprecated protocols, or lack current security updates. These indicators allow security teams to quickly flag systems that require isolation, compensating controls, or replacement.

Bug bounty programs (A) rely on external researchers and are not designed to inventory internal assets. Package monitoring (C) tracks software behavior and changes but does not identify system age or support status. Dynamic analysis (D) evaluates running applications for vulnerabilities, not infrastructure lifecycle status.

Because vulnerability scans provide broad visibility into system versions and supportability, the correct answer is B: Vulnerability scan.

Many IoT devices connect to the network via wireless access points. Reviewing these logs would reveal when the IoT device first connected, as well as any suspicious or anomalous traffic patterns associated with the exploit’s initiation.

An Access Control List (ACL) is a technical mechanism used to explicitly define permissions for files, folders, or other resources. ACLs specify which users or system processes are granted access to objects and what operations are allowed on given objects. This allows the administrator to centrally and granularly manage file permissions for a group or team.

An AI tool developed internally for automating a ticketing system represents intellectual property (IP). Security+ SY0-701 defines IP as proprietary creations developed by an organization, such as software, machine learning models, algorithms, and trade secrets. This type of data must be protected because it provides competitive advantage and is often contractually bound.

The scenario notes the tool is developed under a specific contract, meaning it is bound by ownership, licensing, and confidentiality agreements. Protecting IP is critical to prevent theft, unauthorized reuse, or compromise that could affect legal obligations or business value.

Classified (A) refers to government-protected national security information. Regulated information (B) includes data covered by laws such as HIPAA or PCI-DSS. Open source (C) refers to publicly shared code, which this AI tool is not.

Thus, the correct category for this data is D: Intellectual property.

Detailed Explanation:

Tokenization replaces sensitive data with non-sensitive surrogate values that retain the necessary format but are meaningless without access to the original data. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Data Masking and Tokenization"​​.

Monitoring outbound traffic is essential for detecting unauthorized data exfiltration from a system. A new vulnerability that allows malware to move data unauthorizedly would typically attempt to send this data out of the network. By monitoring outbound traffic, security tools can detect unusual data transfers, trigger alerts, and help prevent the exfiltration of sensitive information.

The principle of least privilege is a security concept that limits access to resources to the minimum level needed for a user, a program, or a device to perform a legitimate function. It is a cybersecurity best practice that protects high-value data and assets from compromise or insider threat. Least privilege can be applied to different abstraction layers of a computing environment, such as processes, systems, or connected devices. However, it is rarely implemented in practice.

In this scenario, the IT manager is setting up the principle of least privilege by restricting access to the administrator console of the help desk software to only two authorized users: the IT manager and the help desk lead. This way, the IT manager can prevent unauthorized or accidental changes to the software configuration, data, or functionality by other help desk staff. The other help desk staff will only have access to the normal user interface of the software, which is sufficient for them to perform their job functions.

The other options are not correct. Hardening is the process of securing a system by reducing its surface of vulnerability, such as by removing unnecessary software, changing default passwords, or disabling unnecessary services. Employee monitoring is the surveillance of workers’ activity, such as by tracking web browsing, application use, keystrokes, or screenshots. Configuration enforcement is the process of ensuring that a system adheres to a predefined set of security settings, such as by applying a patch, a policy, or a template.

Virtual Desktop Infrastructure (VDI) allows a company to host desktop environments on a centralized server. Offshore teams can access these virtual desktops remotely, ensuring that sensitive data stays within the company’s infrastructure without the need to provide physical devices to the team. This solution is ideal for maintaining data security while enabling remote work, as all data processing occurs on the company's secure servers.

CompTIA Security+ SY0-701 Course Content: VDI is discussed as a method for securely managing remote access to company resources without compromising data security​​.

Comprehensive and Detailed In-Depth Explanation:

AWeb Application Firewall (WAF)is designed toprotect web applications from attackssuch asCross-Site Scripting (XSS)by filtering and monitoring HTTP traffic between the internet and a web application.

Next-Generation Firewalls (NGFW) (A)provide advanced network security but are not specifically designed to protect web applications from XSS attacks.

Unified Threat Management (UTM) (B)provides multiple security functions but lacks the specialized application-layer protection needed to mitigate XSS.

Network Access Control (NAC) (D)controls device access to the network but does not prevent web-based attacks.

AWAF is the best solutionfor protecting web servers fromXSS, SQL injection, and other web-based threats.

Recovery Time Objective (RTO)defines themaximum acceptable downtimebefore business operationsmust be restored. It helps organizations set expectations for recovery speed and prioritize system restoration accordingly.

A (likelihood of an incident and cost)relates to risk assessment, not RTO.

B (roles and responsibilities)falls underincident response planning, not RTO.

C (state of restored systems)is covered byRecovery Point Objective (RPO), not RTO.

Badge access and access control vestibule are two of the best ways to ensure only authorized personnel can access a secure facility. Badge access requires the personnel to present a valid and authenticated badge to a reader or scanner that grants or denies access based on predefined rules and permissions. Access control vestibule is a physical security measure that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure area. The personnel must enter the vestibule and wait for the first door to close and lock before the second door can be opened. This prevents tailgating or piggybacking by unauthorized individuals. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 4, pages 197-1981

RBAC stands for Role-Based Access Control, which is a method of restricting access to data and resources based on the roles or responsibilities of users. RBAC simplifies the management of permissions by assigning roles to users and granting access rights to roles, rather than to individual users. RBAC can help enforce the principle of least privilege and reduce the risk of unauthorized access or data leakage. The other options are not as suitable for the scenario asRBAC, as they either do not prevent access based on responsibilities, or do not apply a simplified format. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 133 1

Comprehensive and Detailed Explanation From Exact Extract:

End-of-life (EOL) systems no longer receive security patches, vendor support, or vulnerability updates. Because of this, they are highly susceptible to exploitation, especially if attackers can reach them over a network. When the system is business-critical and cannot be decommissioned, the most effective strategy is isolation, also known as network segmentation, air-gapping, or restrictive network zoning. Isolation removes direct exposure to external and internal threats by limiting communication paths to only essential systems and users.

According to the Security+ SY0-701 guidance, isolating legacy systems helps reduce the attack surface when patching is no longer possible. Monitoring (A) is useful for detection but does not prevent exploitation. Decommissioning (C) would be ideal but is not possible for business-critical systems, as stated in the question. Encryption (D) protects data confidentiality but does not stop an attacker from exploiting vulnerabilities in an unpatched OS or application.

Isolation is a recommended compensating control for legacy and unsupported systems in SY0-701’s Security Architecture & Resilience domain, which emphasizes micro-segmentation, firewalls, and restricted access to minimize risk when systems cannot be replaced or patched.

Comprehensive and Detailed Explanation From Exact Extract:

VM escape occurs when an attacker inside a virtual machine breaks out of the guest OS and gains access to the underlying host hypervisor or other virtual machines. In this scenario, the penetration tester executes a script to inject a malicious payload that allows access to the host filesystem—this is the textbook definition of VM escape.

The SY0-701 exam specifically identifies VM escape as one of the most critical virtualization vulnerabilities, as it defeats isolation and can compromise entire virtual environments. This typically results from flaws in hypervisor software, improper sandboxing, or insecure VM tools.

Cross-site scripting (B) affects web applications and browsers, not hypervisors. Malicious updates (C) involve tampered patch delivery. SQL injection (D) targets databases through application input fields.

Because the attacker moved from a VM to the host system, the correct classification is VM escape, a high-severity virtualization vulnerability.

To establish an encrypted connection (such as HTTPS/TLS) with an externally facing web server, the server must deploy a public key as part of its digital certificate. Clients use the server’s public key to initiate secure communication, which is validated by certificate authorities. The server holds the matching private key, but it is the public key that must be made available for encrypted connections to be established.

A host-based firewall is a software application that runs on an individual endpoint and filters the incoming and outgoing network traffic based on a set of rules. A host-based firewall can help to mitigate the threat posed by suspicious connections between internal endpoints by blocking or allowing the traffic based on the source, destination, port, protocol, or application. A host-based firewall is different from a web application firewall, which is a type of firewall that protects web applications from common web-based attacks, such as SQL injection, cross-site scripting, and session hijacking. A host-based firewall is also different from an access control list, which is a list of rules that control the access to network resources, such as files, folders, printers, or routers. A host-based firewall is also different from an application allow list, which is a list of applications that are authorized to run on an endpoint, preventing unauthorized or maliciousapplications from executing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 254

Typosquatting(also known asURL hijacking) is a type of attack where cybercriminals register domain names similar to legitimate sites but with slight misspellings (e.g., comptiatraning.com instead of comptiatraining.com). Attackers use these fake sites tosteal credentials or distribute malware. Since the user manually entered the URL and reached an unexpected website,this strongly indicates a typosquatting attack.

A honeypot is a decoy system or account designed to attract attackers and detect malicious activity. Creating a user account as a trap fits this definition.

Honeytoken (A) is a decoy data element, honeynet (B) is a network of honeypots, and honeyfile (D) is a decoy file.

Honeypots are important tools in Security Operations and incident detection【6:Chapter 14†CompTIA Security+ Study Guide】

 Non-repudiation is the ability to prove that a message or document was sent or signed by a particular person, and that the person cannot deny sending or signing it. Non-repudiation can be achieved by using cryptographic techniques, such as hashing and digital signatures, that can verify the authenticity and integrity of the message or document. Non-repudiation can be useful for legal, financial, or contractual purposes, as it can provide evidence of the origin and content of the message or document. References = Non-repudiation – CompTIA Security+ SY0-701 – 1.2, CompTIA Security+ SY0-301: 6.1 – Non-repudiation, CompTIA Security+ (SY0-701) Certification Exam Objectives, Domain 1.2, page 2.

A Mobile Device Management (MDM) platform protects organizational mobile devices by enforcing security policies, restricting unauthorized configuration changes, and detecting compromised devices. One of the major vulnerabilities MDM mitigates is jailbreaking, which occurs when a user removes manufacturer restrictions to gain unrestricted access to the file system and install unapproved apps.

Security+ SY0-701 explains that jailbroken devices:

Bypass built-in security protections

Are more susceptible to malware

Can be used for data exfiltration

Violate corporate mobile security policies

MDM solutions detect jailbroken or rooted devices and automatically block them from accessing corporate resources, enforce compliance rules, and remotely wipe devices if necessary.

TPM (A) is a hardware security chip unrelated to MDM. Buffer overflow (B) and SQL injection (D) are software development vulnerabilities, not mobile device policy issues.

Thus, the correct answer is C: Jailbreaking.

Attestation refers to providing formal evidence or proof that a particular process or activity has been completed according to standards or requirements. In this context, attestation involves demonstrating to customers or stakeholders that software developers have received appropriate training on secure coding practices.

Assurance generally refers to confidence or guarantees about the security posture but does not specifically mean proving or certifying training. Due diligence is the effort made to ensure compliance or safety, but it is not the act of proving training has occurred. A contract is a legal agreement, which may include requirements for training but is not the act of proving training itself.

The importance of attestation in compliance and governance processes is discussed in the Security Program Management and Oversight domain in SY0-701 materials【7:Chapter 5†CompTIA Security+ Practice Tests】.

When the government bans a vendor, the legal concern is sanctions—laws that restrict purchasing, using, or importing products from certain companies or countries. The general counsel’s job is to ensure the organization is not violating federal restrictions, export controls, trade compliance laws, or sanctions lists such as OFAC or government procurement bans.

Security+ SY0-701 notes that legal and regulatory compliance is a critical part of risk management, especially when handling prohibited vendors or technologies. Continued use of banned devices could expose the organization to legal penalties, fines, or federal investigation.

Data sovereignty (B) refers to data storage location laws, not hardware bans. Cost of replacement (C) is an operational concern, not a legal one. Loss of license (D) typically applies to software, not network hardware.

Therefore, the general counsel’s primary concern is A: Sanctions.

Recovery Point Objective (RPO) defines the maximum acceptable amount of data loss measured in time. It directly impacts how frequently backups should occur to ensure data can be restored to a point no older than the RPO after a disruption.

Recovery Time Objective (RTO) (A) defines how quickly systems must be restored but does not dictate backup frequency. Mean Time To Repair (MTTR) (C) and Mean Time Between Failures (MTBF) (D) relate to system repair and reliability metrics, not backup schedules.

Understanding and defining RPO is a key part of the Business Impact Analysis (BIA) process covered in the Risk Management domain【6:Chapter 17†CompTIA Security+ Study Guide】.

DLP stands for Data Loss Prevention, which is a tool that can assist with detecting and preventing the unauthorized transmission or leakage of sensitive data, such as a customer’s PII (Personally Identifiable Information). DLP can monitor, filter, and block data in motion (such as emails), data at rest (such as files), and data in use (such as applications). DLP can also alert the sender, the recipient, or the administrator of the data breach, and apply remediation actions, such as encryption, quarantine, or deletion. DLP can help an organization comply with data protection regulations, such as GDPR, HIPAA, or PCI DSS, and protect its reputation and assets. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 78. CompTIA Security+ SY0-701 Exam Objectives, Domain 2.5, page 11.

Encrypting hard drives is a direct implementation of confidentiality, one of the three pillars of the CIA Triad emphasized in CompTIA Security+ SY0-701. Full disk encryption ensures that if a laptop, workstation, or server drive is stolen or accessed without authorization, the data remains unreadable without the decryption key.

This controls unauthorized disclosure and protects sensitive business, financial, and personal information. Drive encryption is widely required for compliance frameworks such as HIPAA, PCI-DSS, and GDPR.

Integrity (A) refers to preventing unauthorized modification of data, which encryption alone does not guarantee. Authentication (B) confirms user identity, such as passwords or biometrics, but is unrelated to data-at-rest protection. Zero Trust (C) is an architectural model requiring constant verification; it is not a control for hard drive encryption.

Since the sole purpose of encrypting storage is to ensure data confidentiality, the correct answer is D.

Comprehensive and Detailed Explanation From Exact Extract:

The scenario describes attackers registering a similar-looking domain to trick users into visiting a malicious site. This matches the definition of typosquatting, also known as URL hijacking or domain spoofing. Typosquatting relies on users mistyping legitimate URLs or failing to notice slight visual differences (e.g., “dropbx.com” instead of “dropbox.com”). Attackers use these domains to distribute malware, steal credentials, or redirect users to phishing pages.

Watering-hole attacks (A) infect legitimate websites frequented by a specific target group, which does not match this scenario. Brand impersonation (B) involves mimicking a company’s identity—often combined with email phishing—but the question specifically mentions creating a similar-looking domain, which is characteristic of typosquatting. Phishing (C) may use these malicious domains, but phishing is a broader social-engineering attack, whereas typosquatting precisely describes the domain manipulation technique.

Security+ SY0-701 emphasizes typosquatting under Social Engineering & Web-based Threats, highlighting how attackers exploit user errors to redirect traffic to malicious destinations. Reducing this risk involves user training, DNS filtering, domain monitoring, and certificate validation.

Cyber insurance is a type of insurance that covers the financial losses and liabilities that result from cyberattacks, such as data breaches, ransomware, denial-of-service, phishing, or malware. Cyber insurance can help a company recover from the costs of restoring data, repairing systems, paying ransoms, compensating customers, or facing legal actions. Cyber insurance is one of the possible strategies that a company can use to address the items listed on the risk register. A riskregister is a document that records the identified risks, their probability, impact, and mitigation strategies for a project or an organization. The four common risk mitigation strategies are:

Accept: The company acknowledges the risk and decides to accept the consequences without taking any action to reduce or eliminate the risk. This strategy is usually chosen when the risk is low or the cost of mitigation is too high.

Transfer: The company transfers the risk to a third party, such as an insurance company, a vendor, or a partner. This strategy is usually chosen when the risk is high or the company lacks the resources or expertise to handle the risk.

Mitigate: The company implements controls or measures to reduce the likelihood or impact of the risk. This strategy is usually chosen when the risk is moderate or the cost of mitigation is reasonable.

Avoid: The company eliminates the risk by changing the scope, plan, or design of the project or the organization. This strategy is usually chosen when the risk is unacceptable or the cost of mitigation is too high.

By purchasing cyber insurance, the company is transferring the risk to the insurance company, which will cover the financial losses and liabilities in case of a cyberattack. Therefore, the correct answer is B. Transfer. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 377. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.1: Risk Management, video: Risk Mitigation Strategies (5:37).

A tabletop exercise is a discussion-based simulation in which stakeholders review and talk through their roles, responsibilities, and actions in response to a hypothetical incident. This allows participants to evaluate and improve response plans without actual disruption.

Salting involves adding a unique value (salt) to each password before hashing it. This means that even if two users have the same password, the added salts ensure their hash values are different. This protects against attacks that exploit identical hash values, such as rainbow table attacks.

The security analyst is creating a "secure configuration guide," which is a set of instructions or guidelines used to configure devices securely before deployment. This guide ensures that thedevices are set up according to best practices to minimize vulnerabilities and protect against potential security threats.

This situation is an example of smishing, which is a type of phishing that uses text messages (SMS) to entice individuals into providing personal or sensitive information to cybercriminals. The best responses to this situation are to add a smishing exercise to the annual company training and to issue a general email warning to the company. A smishing exercise can help raise awareness and educate employees on how to recognize and avoid smishing attacks. An email warning can alert employees to the fraudulent text message and remind them to verify the identity and legitimacy of any requests for information or money. References = What Is Phishing | Cybersecurity | CompTIA, Phishing – SY0-601 CompTIA Security+ : 1.1 - Professor Messer IT Certification Training Courses

File Integrity Monitoring (FIM) is specifically designed to detect and prevent unauthorized changes to critical system files, configuration files, registry entries, binaries, and logs. According to CompTIA Security+ SY0-701, FIM creates a cryptographic baseline (usually via hashing) of protected system files. Any attempt to modify, add, or delete protected files immediately triggers an alert, enabling rapid detection of tampering—whether caused by malware, insider threats, or misconfigurations.

NIDS (A) monitors network traffic, not system-level modifications. DLP (B) prevents unauthorized data exfiltration, not system-file tampering. NAC (C) controls device access to the network but does not protect system files.

FIM is a core tool for ensuring system integrity in compliance frameworks such as PCI-DSS, which explicitly requires organizations to monitor critical system files. By preventing unauthorized changes to system-level data and alerting administrators to suspicious activity, FIM provides a strong defensive mechanism against malware, ransomware, and configuration drift.

Thus, FIM is the correct answer.

Infrastructure as Code (IaC) enables organizations to automate the provisioning, configuration, and deployment of servers through machine-readable scripts rather than manual processes. SY0-701 emphasizes IaC as a key component of DevOps and secure deployment pipelines. By using IaC, server builds become repeatable, standardized, version-controlled, and much faster.

This directly addresses the company's goals:

Better control: IaC ensures predictable, consistent configuration across all servers.

Standardization: Scripts eliminate drift by applying identical configurations.

Lower build time: Automation significantly accelerates server creation and eliminates manual intervention.

IoT (A) refers to Internet-connected smart devices and is unrelated to server deployment. PaaS (C) offers development platforms but does not automate infrastructure builds. ICS (D) refers to industrial control systems, not IT server architecture.

Therefore, the only correct architecture that meets all objectives is IaC, a foundational technology for modern automated infrastructure.

The correct answer is immutability, which is a critical concept in backup security and ransomware resilience as covered in the CompTIA Security+ SY0-701 study guide. Immutability ensures that backup data, once written, cannot be altered, modified, or deleted for a defined period of time. This protection is essential in ransomware recovery scenarios because modern ransomware often attempts to encrypt or delete backups to prevent recovery.

Immutable backups are typically implemented using write-once-read-many (WORM) storage or immutable cloud storage configurations. When immutability is enforced, even administrators or attackers with elevated privileges cannot modify the backup contents during the retention window. As a result, organizations can be confident that their backups remain in a known-good, unaltered state, free from ransomware infection or tampering.

The other options do not provide the same guarantee. Destruction refers to permanently deleting data, which would eliminate backups rather than protect them. Sanitization is the process of securely erasing data from storage media and is unrelated to preserving clean backups. Retention defines how long backups are kept but does not protect them from being modified or encrypted during that period.

From a Security+ SY0-701 perspective, immutability is closely tied to resilience, recovery, and data protection strategies. It supports business continuity by ensuring that organizations can reliably restore systems after an attack. Immutable backups are a cornerstone of modern ransomware defense strategies because they prevent attackers from corrupting recovery data. Therefore, immutability is the best and most effective control to guarantee that backups used for recovery are not infected.

A service level agreement (SLA) is a type of agreement that defines the expectations and responsibilities between a service provider and a customer. It usually includes the quality, availability, and performance metrics of the service, as well as the time frame in which the provider needs to respond to service requests, incidents, or complaints. An SLA can help ensure that the customer receives the desired level of service and that the provider is accountable for meeting the agreed-upon standards.

To analyze malware behavior in detail, the best approach is toexecute the malware in a sandbox (D)andcapture its network activity. This providesreal-time analysisof how the malware behaves, spreads, and communicates.

This method is highlighted inDomain 2.1under"Analyzing indicators of compromise"and usingsandboxing and packet captureto study malware.

Key escrow is a method of storing encryption keys in a secure location, such as a trusted third party or a hardware security module (HSM). Key escrow is important for FDE because it allows the recovery of encrypted data in case of lost or forgotten passwords, device theft, or hardware failure. Key escrow also enables authorized access to encrypted data for legal or forensic purposes.

TPM presence is a feature of some laptops that have a dedicated chip for storing encryption keys and other security information. TPM presence is important for FDE because it enhances the security and performance of encryption by generating and protecting the keys within the chip, rather than relying on software or external devices. TPM presence also enables features such as secure boot, remote attestation, and device authentication. 

A high-availability network is a network that is designed to minimize downtime and ensure continuous operation of critical services and applications. To achieve this goal, a high-availability network must consider two important factors: ease of recovery and attack surface.

Ease of recovery refers to the ability of a network to quickly restore normal functionality after a failure, disruption, or disaster. A high-availability network should have mechanisms such as redundancy, failover, backup, and restore to ensure that any single point of failure does not cause a complete network outage. A high-availability network should also have procedures and policies for incident response, disaster recovery, and business continuity to minimize the impact of any network issue on the organization’s operations and reputation.

Attack surface refers to the exposure of a network to potential threats and vulnerabilities. A high-availability network should have measures such as encryption, authentication, authorization,firewall, intrusion detection and prevention, and patch management to protect the network from unauthorized access, data breaches, malware, denial-of-service attacks, and other cyberattacks. A high-availability network should also have processes and tools for risk assessment, threat intelligence, vulnerability scanning, and penetration testing to identify and mitigate any weaknesses or gaps in the network security.

The correct answer is having privileged access to client systems and becoming a target for attackers, which directly reflects a major risk discussed in the Security+ SY0-701 domain of Security Program Management and Oversight, specifically within third-party and supply chain risk management. Supply chain service providers often require elevated or privileged access to an organization’s systems to perform maintenance, monitoring, software updates, or support services. This level of access significantly expands the organization’s attack surface.

When a vendor has privileged access, attackers may target the service provider as an indirect path into the primary organization. This type of compromise is especially dangerous because malicious activity may appear legitimate, using trusted credentials and authorized connections. The Security+ study guide emphasizes that third-party compromises can bypass traditional perimeter defenses, making them particularly difficult to detect and contain. As a result, vendors can unintentionally introduce vulnerabilities even if the organization’s internal security controls are strong.

The other options do not directly introduce a security vulnerability. Delayed hardware shipments affect availability and project timelines but do not create a security weakness. Outsourcing customer service may introduce privacy or compliance concerns, but it does not inherently create a technical vulnerability unless combined with poor access controls. Failing to encrypt internal databases is an internal security failure, not a supply chain issue caused by a service provider.

From a Security+ perspective, managing this risk requires strong contractual controls, least-privilege access, continuous monitoring, and audit rights. Organizations must treat vendors as extensions of their own environment. Therefore, privileged access held by a supply chain provider—and the increased likelihood of that provider being targeted—is the most accurate explanation of how a supply chain service provider can introduce a security vulnerability.

"Network segmentation is a security practice that divides a network into smaller, isolated segments to limit access and reduce the attack surface. Firewalls are commonly used to enforce segmentation by creating rules that allow or deny traffic based on source, destination, and port. Tomeet compliance requirements, such as restricting access to internal servers, firewall rules can be configured to block all external traffic while permitting only authorized internal systems to communicate with the segmented servers. This ensures that sensitive resources are isolated from unauthorized access."

Recurring training is a type of security awareness training that is conducted periodically to refresh and update the knowledge and skills of the users. Recurring training can help improve the situational and environmental awareness of existing users as they transition from remote to in-office work, as it can cover the latest threats, best practices, and policies that are relevant to their work environment. Modifying the content of recurring training can ensure that the users are aware of the current security landscape and the expectations of their roles. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 5, page 232.

Code signing is a technique that uses cryptography to verify the authenticity and integrity of the code created by the company. Code signing involves applying a digital signature to the code using a private key that only the company possesses. The digital signature can be verified by anyone who has the corresponding public key, which can be distributed through a trusted certificate authority. Code signing can prevent unauthorized modifications, tampering, or malware injection into the code, and it can also assure the users that the code is from a legitimate source. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 74.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Incident Response and Containment"​​.

The scenario describes an attacker who obtained credentials from a compromised system's memory and used them without cracking to move laterally within the network. This technique is known as a "pass-the-hash" attack, where the attacker captures hashed credentials (e.g., NTLM hashes) and uses them to authenticate and gain access to other systems without needing to know the plaintext password. This is a common attack method in environments where weak security practices or outdated protocols are in use.

A buffer overflow is a type of software vulnerability that occurs when an application writes more data to a memory buffer than it can hold, causing the excess data to overwrite adjacent memory locations. This can lead to unexpected behavior, such as crashes, errors, or code execution. A buffer overflow can be exploited by an attacker to inject malicious code or commands into the application, which can compromise the security and functionality of the system. An organization’s internet-facing website was compromised when an attacker exploited a buffer overflow. To best protect against similar attacks in the future, the organization should deploy a web application firewall (WAF). A WAF is a type of firewall that monitors and filters the traffic between a web application and the internet. A WAF can detect and block common web attacks, such as buffer overflows, SQL injections, cross-site scripting (XSS), and more. A WAF can also enforce security policies and rules, such as input validation, output encoding, and encryption. A WAF can provide a layer of protection for the web application, preventing attackers from exploiting its vulnerabilities and compromising its data. References = Buffer Overflows – CompTIA Security+ SY0-701 – 2.3, Web Application Firewalls – CompTIA Security+ SY0-701 – 2.4, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]

Smishing is a type of phishing attack that uses text messages or common messaging apps to trick victims into clicking on malicious links or providing personal information. The scenario in the question describes a smishing attack that uses pretexting, which is a form of social engineering that involves impersonating someone else to gain trust or access. The unknown number claims to be the company’s CEO and asks the employee to purchase gift cards, which is a common scam tactic. Vishing is a similar type of attack that uses phone calls or voicemails, while phishing is a broader term that covers any email-based attack. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 771; Smishing vs. Phishing: Understanding the Differences2

The company should implement Security Assertion Markup Language (SAML) to integrate the vendor's security tool with their existing user directory. SAML is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP), enabling Single Sign-On (SSO). This allows the company to use its existing directory services for authentication, avoiding the need to manage a separate set of user credentials for the new tool.

Detailed Explanation:

Corrective controls, such as auditing and versioning, help prevent unauthorized changes to financial data, ensuring data integrity and compliance with regulations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Controls for Financial Systems"​​.

To identify the exactcommand or input usedduring a SQL injection attack, theapplication log (B)is the most relevant. It records inputs, errors, and processing activities within the application layer.

UnderDomain 2.1, CompTIA emphasizes reviewingapplication logsto detect indicators of malicious activity, includingweb application attackslike SQL injection.

A VPN is a virtual private network that creates a secure tunnel between two or more devices over a public network. A VPN can encrypt and authenticate the data, as well as hide the IP addresses and locations of the devices. A jump server is a server that acts as an intermediary between a user and a target server, such as a production server. A jump server can provide an additional layer of security and access control, as well as logging and auditing capabilities. A firewall is a device or software that filters and blocks unwanted network traffic based on predefined rules. A firewall can protect the internal network from external threats and limit the exposure of sensitive services and ports. A security analyst should recommend setting up a VPN and placing the jump server inside the firewall to improve the security of the remote desktop access to the production network. This way, the remote desktop service will not be exposed to the public network, and only authorized users with VPN credentials can access the jump server and then the production server. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 8: Secure Protocols and Services, page 382-383 1; Chapter 9: Network Security, page 441-442 1

Input validation is a security technique that checks the user input for any malicious or unexpected data before processing it by the application. Input validation can prevent various types of attacks, such as injection, cross-site scripting, buffer overflow, and command execution, that exploit the vulnerabilities in the application code. Input validation can be performed on both the client-side and the server-side, using methods such as whitelisting, blacklisting, filtering, sanitizing, escaping, and encoding. By including regular expressions in the source code to remove special characters from the variables set by the forms in the web application, the organization adopted input validation as a security technique. Regular expressions are patterns that match a specific set of characters or strings, and can be used to filter out any unwanted or harmful input. Special characters, such as $, |, ;, &, `, and ?, can be used by attackers to injectcommands or scripts into the application, and cause damage or data theft. By removing these characters from the input, the organization can reduce the risk of such attacks.

Identify embedded keys, code debugging, and static code analysis are not the security techniques that the organization adopted by making this addition to the policy. Identify embedded keys is a process of finding and removing any hard-coded keys or credentials from the source code, as these can pose a security risk if exposed or compromised. Code debugging is a process of finding and fixing any errors or bugs in the source code, which can affect the functionality or performance of the application. Static code analysis is a process of analyzing the source code without executing it, to identify any vulnerabilities, flaws, or coding standards violations. These techniques are not related to the use of regular expressions to remove special characters from the input.

A reflected denial of service (RDoS) attack is a type of DDoS attack that uses spoofed source IP addresses to send requests to a third-party server, which then sends responses to the victim server. The attacker exploits the difference in size between the request and the response, which can amplify the amount of traffic sent to the victim server. The attacker also hides their identity by using the victim’s IP address as the source. A RDoS attack can target DNS servers by sending forged DNS queries that generate large DNS responses. This can flood the network interface of the DNS server and prevent it from serving legitimate requests from end users. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215-216 1

The most important security concern when using legacy systems is the lack of vendor support. Without support from the vendor, systems may not receive critical security patches and updates, leaving them vulnerable to exploitation. This lack of support can result in increased risk of security breaches, as vulnerabilities discovered in the software may never be addressed.

References = CompTIA Security+ SY0-701 study materials, particularly in the context of risk management and the challenges posed by legacy systems​​.

If email filtering tools are not tuned based on reported emails, malicious emails will continue to bypass filters. Effective filtering depends on feedback and updating rules with real threat data.

Flagging legitimate emails (A) would cause false positives, shadow IT (C) and forwarding personal emails (D) are less relevant to the filtering bypass.

Tuning email filters is part of continuous Security Operations processes【6:Chapter 14†CompTIA Security+ Study Guide】.

Shadow IT is the term used to describe the use of unauthorized or unapproved IT resources within an organization. The marketing department set up its own project management software without telling the appropriate departments, such as IT, security, or compliance. This could pose a risk to the organization’s security posture, data integrity, and regulatory compliance1.

An intrusion prevention system (IPS) is a security device that monitors network traffic and blocks or modifies malicious packets based on predefined rules or signatures. An IPS can prevent attacks that exploit known vulnerabilities in older browser versions by detecting and dropping the malicious packets before they reach the target system. An IPS can also perform other functions, such as rate limiting, encryption, or redirection. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3: Securing Networks, page 132.

Quantitative risk analysis involves assigning numeric values to risk components, such as potential financial losses. Estimating the replacement cost of a physical server is part of calculating the potential impact and exposure during this process.

Disaster recovery tests (B) validate recovery procedures, physical security controls review (C) assesses physical protections, and threat modeling (D) identifies potential threats and attack vectors.

Quantitative analysis is a key part of risk management addressed in the SY0-701 Risk Management domain【6:Chapter 17†CompTIA Security+ Study Guide】

Integrating each SaaS solution with an Identity Provider (IdP) is the most effective way to address the security issue. This approach allows for Single Sign-On (SSO) capabilities, where users can access multiple SaaS applications with a single set of credentials while maintaining strong password policies across all services. It simplifies the user experience and ensures consistent security enforcement across different SaaS platforms.

The chmod command is used to change file permissions on Unix and Linux systems. If the /etc/shadow file has permissions beyond the baseline recommendation, the systems administrator should use chmod to modify the file's permissions, ensuring it adheres to the security baseline and limits access to authorized users only.

A Host-Based Intrusion Prevention System (HIPS) provides preventive and detective security controls. Security+ SY0-701 explains that:

As a preventive control (B), HIPS actively blocks malicious behavior, stops unauthorized changes, prevents exploit execution, and enforces host-level protection. It prevents malware, intrusions, and unauthorized actions before they occur.

As a detective control (F), HIPS monitors host activity, detects suspicious patterns, logs events, and alerts administrators when threats are observed.

Directive controls (A) involve policy, not technical tools. Physical controls (C) include barriers and locks. Corrective controls (D) restore systems after incidents. Compensating controls (E) are alternatives when primary controls aren't available.

Therefore, the correct answers are B (Preventive) and F (Detective).

Automated vulnerability scanningis thefirst step in identifying system weaknesses. These scans systematically check for outdated software, misconfigurations, and known vulnerabilities in a network.

Penetration testing (B)is conducted after vulnerabilities are identified.

Threat hunting (C)focuses on detecting unknown threats, not listing vulnerabilities.

Comprehensive and Detailed Explanation From Exact Extract:

Key escrow is the process of storing encryption keys (or copies of them) with a trusted third party so data can be recovered if the primary decryption key is lost. In Security+ SY0-701, escrow is emphasized as a required safeguard for organizations that rely heavily on encryption, especially for regulated data or systems requiring guaranteed recoverability.

A CSR (A) is a Certificate Signing Request and does not store keys. Salting (B) is used with hashing to prevent password attacks and does not assist in data recovery. A root of trust (C) ensures secure hardware initialization but does not store backup decryption keys.

Key escrow directly addresses scenarios where encryption keys are misplaced, corrupted, deleted, or lost due to employee departure or system failure. Without escrow, encrypted data could become permanently inaccessible.

Thus, the correct answer is Escrow, the only mechanism specifically designed to allow recovery when decryption keys are unavailable.

The correct answer is Compensating because a bastion host is being used as an alternative safeguard to reduce risk when a primary control cannot yet be fully implemented. In the context of the Security+ SY0-701 objectives, compensating controls are designed to provide protection when standard preventive controls are not available, effective, or feasible—such as during a zero-day exploit where no vendor patch or permanent fix exists.

A zero-day exploit represents a vulnerability that is actively being exploited before developers or vendors have released a fix. Since patching is not immediately possible, organizations must rely on compensating controls to limit exposure and reduce the likelihood or impact of exploitation. A bastion host is a hardened system placed in a network segment—often in a demilitarized zone (DMZ)—that acts as a controlled access point between untrusted and trusted networks. By routing access through this tightly secured host, the analyst reduces the attack surface and restricts direct access to internal systems that may be vulnerable to the zero-day.

Option B, Detective, is incorrect because detective controls are focused on identifying or alerting on malicious activity after it occurs, such as logging, monitoring, or intrusion detection systems. Option C, Operational, refers to processes and procedures carried out by people, such as incident response or change management, rather than a technical safeguard. Option D, Physical, applies to tangible protections like locks, cameras, or fencing, which are not relevant in this network-based scenario.

The SY0-701 study guide emphasizes the importance of layered security and adaptive risk management. When preventive controls fail or are temporarily unavailable, compensating controls like bastion hosts, network segmentation, and access restrictions allow organizations to maintain security posture and continuity of operations while longer-term solutions are developed.

File Integrity Monitoring (FIM) detects unauthorized changes to files, including deletions, modifications, and permission alterations. When protecting shared data, FIM creates baseline hashes of files and monitors them for unexpected changes. Any deviation triggers alerts, enabling rapid investigation and remediation.

Security+ SY0-701 identifies FIM as a crucial tool for:

Integrity monitoring

Detecting unauthorized file deletion

Identifying malicious or accidental permission changes

Supporting compliance (PCI-DSS, HIPAA, etc.)

DLP (A) protects against data leakage but does not detect permission misconfiguration or deleted files. EDR (B) monitors endpoint activity but is not optimized for shared file integrity. ACL (D) defines permissions but does not track changes.

Thus, C (FIM) is the correct solution.

Detailed Explanation:MAC filtering allows network administrators to control device access by specifying allowed MAC addresses. This prevents unauthorized devices, such as a laptop plugged into a network port, from gaining access. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Threats and Vulnerabilities, Section: "Network Access Control Methods"​​.

Comprehensive and Detailed Explanation From Exact Extract:

If MFA is in place yet attackers still breach the system, the compromise most likely resulted from social engineering, specifically pretexting. Pretexting occurs when an attacker fabricates a convincing scenario (a “pretext”) to trick the victim into revealing authentication information, such as OTP codes, MFA prompts, or login details. Even strong MFA cannot prevent an attack when a human is tricked into voluntarily providing the code.

Smishing (A) involves fraudulent SMS messages, but no messaging is mentioned in the scenario. Typosquatting (B) involves deceptive URLs that appear similar to legitimate sites and is unrelated to MFA compromise. Espionage (C) refers to stealing sensitive or national-security-related information, not bypassing MFA protections.

Security+ SY0-701 details pretexting under Social Engineering Attacks, emphasizing that MFA does not fully mitigate human manipulation. Attackers frequently impersonate IT staff, vendors, or automated systems to convince victims to “verify” or “confirm” credentials. This perfectly matches a breach where MFA was present but still circumvented through deception.

The scenario shows MD5 hashed password values. The most likely reason the security administrator is focusing on these values is to protect against pass-the-hash attacks. In this type of attack, an attacker can use a captured hash to authenticate without needing to know the actual plaintext password. By managing and monitoring these hashes, the administrator can implement strategies to mitigate this type of threat.

Code signing (D)usescryptographic digital signaturesto confirm theintegrity and authenticityof software code. It ensures that the code hasnot been alteredafter being signed, providing assurance that the application is trustworthy.

This aligns withCompTIA Security+ SY0-701 Domain 2.3: Application security techniques, which includescode signingas a method to validatecode integrity.

Monolithic code architecture significantly limits an organization’s ability to benefit from containerization. Containers are designed to package and run small, modular, loosely coupled services, often following a microservices architecture. CompTIA Security+ SY0-701 explains that containers enhance security by reducing attack surface, improving isolation, and allowing granular patching—but only when applications are designed to support this model.

Monolithic applications bundle all components (UI, business logic, database access) into a single large codebase. This makes it difficult to isolate functions into separate containers, apply least privilege, or patch individual components without redeploying the entire application. As a result, security improvements such as rapid updates, minimal images, and fine-grained access controls are harder to achieve.

Regulatory compliance (A) may add requirements but does not inherently block container use. Patch availability (B) affects maintenance but not architecture suitability. Kernel version (C) can be a constraint, but modern container platforms manage kernel compatibility effectively.

Because containers are best suited for modular applications, monolithic code is the primary limitation, making D the correct answer.

A tabletop exercise is the most effective way to quickly assess a cybersecurity team’s readiness to respond to a threat scenario. CompTIA Security+ SY0-701 describes tabletop exercises as discussion-based simulations where incident response team members walk through a realistic scenario to evaluate procedures, decision-making, communication, and coordination. These exercises are specifically designed to be conducted in a short timeframe while still providing meaningful insight into preparedness.

Executing a tabletop exercise allows management to observe how the team identifies threats, escalates incidents, assigns roles, and follows the incident response plan. Documenting performance results helps formalize findings, identify gaps, and improve playbooks and procedures without the complexity of a live incident or full-scale simulation.

Option A is informal and does not test real-time decision-making. Option B focuses on vulnerability discovery, not response readiness. Option D can be effective but is time-consuming and not suited for rapid assessment.

Therefore, C: Execute a tabletop exercise and document the performance results is the correct answer.

"Group Policy Objects (GPOs) are a feature of Microsoft Windows Active Directory that allow administrators to centrally manage and configure settings across multiple systems in an efficient manner. When a vulnerability such as SMBv1 (Server Message Block version 1) is identified onmultiple servers, GPOs can be used to disable this outdated and insecure protocol across all affected systems simultaneously. By creating a GPO to enforce a policy that disables SMBv1, the organization can ensure consistent remediation without manually configuring each server individually, making it the most efficient solution for domain-joined environments."

Mitigate is the risk management strategy that involves reducing the likelihood or impact of a risk. If a legacy application is critical to business operations and there are preventative controls that are not yet implemented, the enterprise should adopt the mitigate strategy first to address the existing vulnerabilities and gaps in the application. This could involve applying patches, updates, or configuration changes to the application, or adding additional layers of security controls around the application. Accept, transfer, and avoid are other risk management strategies, but they are not the best options for this scenario. Accept means acknowledging the risk and accepting the consequences without taking any action. Transfer means shifting the risk to a third party, such as an insurance company or a vendor. Avoid means eliminating the risk by removing the source or changing the process. These strategies may not be feasible or desirable for a legacy application that is critical to business operations and has no preventative controls in place. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1221; A Risk-Based Framework for Legacy System Migration and Deprecation2

Within an organization's Software Development Life Cycle (SDLC), an Information Security Policy is a vital component. It outlines the rules and procedures for ensuring that the organization’s IT assets and data are protected throughout the development process. Ensuring secure coding practices, access controls, and regular security testing is fundamental in preventing vulnerabilities in applications.

Other options like service-level agreements and branch protection requirements are less likely to be integral to SDLC processes. Penetration testing methodology, while useful, is generally considered outside the scope of the SDLC​​.

A two-person integrity security control is implemented to minimize the risk of errors or unauthorized actions. This control ensures that at least two individuals are involved in critical operations, which helps to verify the accuracy of the process and prevents unauthorized users from acting alone. It's a security measure commonly used in sensitive operations, like financial transactions or access to critical systems, to ensure accountability and accuracy.

The correct answer is Zero Trust because it directly aligns with all three stated requirements: creating secure zones, enforcing consistent access control policies across the organization, and reducing the overall threat surface. In the Security+ SY0-701 framework, Zero Trust is a modern security architecture model based on the principle of never trust, always verify. It assumes that threats may already exist inside or outside the network and therefore requires continuous validation of users, devices, and sessions.

Zero Trust architectures segment environments into secure zones, often using microsegmentation, to prevent lateral movement by attackers. This directly reduces the scope of threats by limiting what an attacker can access even if one component is compromised. Enforcing company-wide access control policies is another core Zero Trust principle, as access decisions are centrally governed and based on identity, device posture, context, and least privilege rather than network location.

Option B, AAA (Authentication, Authorization, and Accounting), is an access control framework, but it does not inherently define secure zones or reduce threat scope through segmentation. Option C, Non-repudiation, ensures actions cannot be denied later and is primarily related to auditing and accountability, not access control architecture. Option D, CIA, refers to confidentiality, integrity, and availability—fundamental security goals rather than an implementation model.

The SY0-701 study guide emphasizes Zero Trust as a strategic approach to minimizing attack surfaces, enforcing least privilege, and protecting enterprise resources regardless of user location or network boundaries. By continuously validating access and restricting trust, Zero Trust architectures significantly reduce risk and improve resilience against both internal and external threats.

In summary, the combination of secure zones, centralized access control enforcement, and reduced threat exposure clearly indicates the implementation of a Zero Trust architecture.

Implementing playbooks as part of a SOAR (Security Orchestration, Automation, and Response) platform enables the automation of routine security tasks and the standardized response to common alerts. Playbooks help filter and validate alerts, reducing the number of false positives that analysts need to manually investigate. SOAR tools are specifically designed to improve efficiency, consistency, and accuracy in incident response, allowing analysts to focus on genuine threats rather than being overwhelmed by noise.

A tabletop exercise simulates incident scenarios to test and validate the effectiveness of an organization's Incident Response Plan (IRP), identifying gaps and areas needing updates. It promotes team readiness without disrupting operations.

Addressing audit findings (A), collecting remediation times (B), and calculating ROI (D) are separate activities and not the primary purpose of tabletop exercises.

This practice is an integral part of Security Operations and Incident Response training in SY0-701【6:Chapter 14†CompTIA Security+ Study Guide】.

The best methods for hardening end user devices are Full Disk Encryption (FDE) and Endpoint Protection. FDE (A) protects data at rest on laptops and workstations, ensuring that data remains unreadable if devices are lost or stolen—an explicit best practice in Security+ SY0-701.

Endpoint protection (D), including EDR/anti-malware, hardens devices by preventing, detecting, and responding to malicious activity at the host level. Together, these controls provide strong baseline protection for confidentiality and threat prevention.

Group-level permissions (B) and account lockout (C) are important access controls but do not comprehensively harden devices against malware and data exposure. Proxy servers (E) and segmentation (F) are network controls rather than endpoint hardening measures.

Therefore, the correct selections are A: Full disk encryption and D: Endpoint protection.

Explanation (Security+ SY0-701 aligned):

Deception technologies—such as honeypots, honeynets, honeyfiles, and honeytokens—are designed to intentionally lure attackers into controlled, monitored environments. Their primary purpose is not to block attacks outright or replace preventive controls, but to observe attacker behavior, techniques, and tools in a safe way. This allows organizations to collect high-value threat intelligence without exposing real production systems or sensitive data.

In the Security+ SY0-701 objectives (General Security Concepts), deception and disruption technologies are highlighted as tools that increase attacker cost and uncertainty while improving defender visibility. When an attacker interacts with a honeypot or accesses a honeyfile, it generates a strong indicator of malicious intent because legitimate users should never touch these resources. This makes deception technologies extremely valuable for early detection and analysis of attacks.

Why the other options are incorrect:

A. Preventing malware installation is the role of endpoint protection platforms (EPP/EDR), not deception technologies.

B. Blocking all external traffic before it reaches critical systems describes perimeter defenses like firewalls or gateways, not deception.

D. Detecting insider threats by monitoring privileged accounts is handled by IAM controls, logging, and UEBA, not deception systems.

In short, deception technologies are proactive detection and intelligence-gathering tools. They don’t stop attackers at the gate; instead, they trick attackers into revealing themselves and their methods, giving defenders insight that strengthens the overall security strategy.

Explanation (Security+ SY0-701 aligned):

To ensure an organization can review the controls and performance of a service provider or vendor, it should include a right-to-audit clause in its contract. A right-to-audit clause explicitly grants the customer the legal authority to inspect, assess, or audit the vendor’s security controls, processes, and compliance posture. This is a key concept under Security Program Management and Oversight, particularly within third-party risk management.

In the SY0-701 objectives, third-party risk management emphasizes the importance of contractual controls that allow organizations to verify that vendors are meeting security, privacy, and compliance obligations. A right-to-audit clause enables activities such as reviewing policies, examining control effectiveness, validating compliance with standards (for example, SOC reports), and confirming that agreed-upon safeguards are actually in place. Without this clause, the organization may have no formal mechanism to independently verify vendor claims.

Why the other options are incorrect:

A. Service-level agreement (SLA): SLAs define performance metrics like uptime, response time, and availability. They do not usually grant audit authority over security controls.

B. Memorandum of agreement (MOA): An MOA outlines general responsibilities and cooperation between parties but typically lacks enforceable audit rights.

D. Supply chain analysis: This is a risk assessment activity, not a contractual mechanism that provides audit access.

From a Security+ perspective, the right-to-audit clause is the most effective and direct way to ensure ongoing visibility and assurance over vendor security controls and performance.

Compliance attestation (B)ensures that devices meetpredefined security policies(e.g., encryption enabled, updated antivirus, latest OS patches) before being allowed access to corporate resources. This is commonly enforced usingMobile Device Management (MDM)systems.

By using compliance checks via MDM, only secure,policy-compliantdevices are promoted from quarantine to trusted network segments.

Threat hunting is the process of proactively searching for signs of malicious activity or compromise in a network, rather than waiting for alerts or indicators of compromise (IOCs) to appear. Threat hunting can help identify new tactics, techniques, and procedures (TTPs) used by malicious actors, as well as uncover hidden or stealthy threats that may have evaded detection by security tools. Threat hunting requires a combination of skills, tools, and methodologies, such as hypothesis generation, data collection and analysis, threat intelligence, and incident response. Threat hunting can also help improve the security posture of an organization by providing feedback and recommendations for security improvements. References = CompTIA Security+ Certification Exam Objectives, Domain 4.1: Given a scenario, analyze potential indicators of malicious activity. CompTIA Security+ Study Guide (SY0-701), Chapter 4: Threat Detection and Response, page 153. Threat Hunting – SY0-701 CompTIA Security+ : 4.1, Video 3:18. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 3.

Geographic dispersion is a strategy that involves distributing the servers or data centers across different geographic locations. Geographic dispersion can help the company to mitigate the risk of weather events causing damage to the server room and downtime, as well as improve the availability, performance, and resilience of the network. Geographic dispersion can also enhance the disaster recovery and business continuity capabilities of the company, as it can provide backup and failover options in case of a regional outage or disruption12.

The other options are not the best ways to address the company’s concern:

Clustering servers: This is a technique that involves grouping multiple servers together to act as a single system. Clustering servers can help to improve the performance, scalability, and fault tolerance of the network, but it does not protect the servers from physical damage or downtime caused by weather events, especially if the servers are located in the same room or building3.

Load balancers: These are devices or software that distribute the network traffic or workload among multiple servers or resources. Load balancers can help to optimize the utilization,efficiency, and reliability of the network, but they do not prevent the servers from being damaged or disrupted by weather events, especially if the servers are located in the same room or building4.

Off-site backups: These are copies of data or files that are stored in a different location than the original source. Off-site backups can help to protect the data from being lost or corrupted by weather events, but they do not prevent the servers from being damaged or disrupted by weather events, nor do they ensure the availability or continuity of the network services.

Brute force is a type of attack that tries to guess the password or other credentials of a user account by using a large number of possible combinations. An attacker can use automated tools or scripts to perform a brute force attack and gain unauthorized access to the account. The domain activity logs show that the user ismith has failed to log in 10 times in a row within a short period of time, which is a strong indicator of a brute force attack. The logs also show that the source IP address of the failed logins is different from the usual IP address of ismith, which suggests that the attacker is using a different device or location to launch the attack. The security analyst should take immediate action to block the attacker’s IP address, reset ismith’s password, and notify ismith of the incident. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 14.

 A bastion host is a special-purpose server that is designed to withstand attacks and provide secure access to internal resources. A bastion host is usually placed on the edge of a network, acting as a gateway or proxy to the internal network. A bastion host can be configured to allowonly certain types of traffic, such as SSH or HTTP, and block all other traffic. A bastion host can also run security software such as firewalls, intrusion detection systems, and antivirus programs to monitor and filter incoming and outgoing traffic. A bastion host can provide administrative access to internal resources by requiring strong authentication and encryption, and by logging all activities for auditing purposes12.

A bastion host is the most secure method among the given options because it minimizes the traffic allowed through the security boundary and provides a single point of control and defense. A bastion host can also isolate the internal network from direct exposure to the internet or other untrusted networks, reducing the attack surface and the risk of compromise3.

Deploying a perimeter network is not the correct answer, because a perimeter network is a network segment that separates the internal network from the external network. A perimeter network usually hosts public-facing services such as web servers, email servers, or DNS servers that need to be accessible from the internet. A perimeter network does not provide administrative access to internal resources, but rather protects them from unauthorized access. A perimeter network can also increase the complexity and cost of network management and security4.

Installing a WAF is not the correct answer, because a WAF is a security tool that protects web applications from common web-based attacks by monitoring, filtering, and blocking HTTP traffic. A WAF can prevent attacks such as cross-site scripting, SQL injection, or file inclusion, among others. A WAF does not provide administrative access to internal resources, but rather protects them from web application vulnerabilities. A WAF is also not a comprehensive solution for network security, as it only operates at the application layer and does not protect against other types of attacks or threats5.

Utilizing single sign-on is not the correct answer, because single sign-on is a method of authentication that allows users to access multiple sites, services, or applications with one username and password. Single sign-on can simplify the sign-in process for users and reduce the number of passwords they have to remember and manage. Single sign-on does not provide administrative access to internal resources, but rather enables access to various resources that the user is authorized to use. Single sign-on can also introduce security risks if the user’s credentials are compromised or if the single sign-on provider is breached6. References = 1: Bastion host - Wikipedia, 2: 14 Best Practices to Secure SSH Bastion Host - goteleport.com, 3: The Importance Of Bastion Hosts In Network Security, 4: What is the network perimeter? | Cloudflare, 5: What is a WAF? | Web Application Firewall explained, 6: [What is single sign-on (SSO)? - Definition from WhatIs.com]

To mitigate the risk of confidential documents being left unattended in Multi-Function Printers (MFPs), implementing an authentication factor that requires in-person action before printing (such as PIN codes or badge scanning) is the most effective measure. This ensures that documents are only printed when the authorized user is present to collect them, reducing the risk of sensitive information being exposed.

A cryptographic vulnerability refers to weaknesses caused by the use of outdated or insecure cryptographic algorithms, protocols, or keys. These vulnerabilities make it easier for attackers to compromise encrypted data or communications. Use of deprecated ciphers or insufficient key lengths are typical examples.

To determine whether the connection was successful after a user clicked on a link in a phishing email, the most relevant log source to analyze would be the network logs. These logs would provide information on outbound and inbound traffic, allowing the analyst to see if the user’s system connected to the remote server specified in the phishing link. Network logs can includedetails such as IP addresses, domains accessed, and the success or failure of connections, which are crucial for understanding the impact of the phishing attempt.

Ransomware is a type of malware that encrypts the victim’s files and demands a ransom for the decryption key. The ransomware usually displays a message on the infected system with instructions on how to pay the ransom and recover the files. The .ryk extension is associated with a ransomware variant called Ryuk, which targets large organizations and demands high ransoms1.

Step 1: Analyze the Data and Question

Scenario:

Company data (directory, compensation report, user data) is found on the dark web.

CIO asks you to investigate and implement the most secure protection for employee accounts.

Task:

Identify weak password practices.

Choose the best containment step that keeps evidence on the host uncompromised.

Step 2: Identify Weak Password Practices

Prompt: Select all weak password practices from the list:

Age

Reuse

Length

Expiration

Complexity

Let’s analyze each:

Age: If passwords are used for a long time without change, it's a weak practice (passwords become easier to compromise over time).

Reuse: Reusing passwords across accounts is a serious weak practice (if one gets leaked, all accounts are at risk).

Length: Short passwords are weak; password length matters. If passwords are too short, that’s a weak practice.

Expiration: Forcing frequent expiration can lead to weaker passwords (users pick simple ones), but not expiring passwords at all is also risky. (For most exams, "expiration" by itself isn't usually called a weak practice unless the policy is poorly set.)

Complexity: Lack of complexity (not requiring numbers, symbols, etc.) is a weak practice.

So, select all that are truly weak practices:

Answer for weak password practices (check all that apply):

✔️ Age

✔️ Reuse

✔️ Length

✔️ Complexity

(Expiration is more controversial; on the exam, the main focus is usually on Age, Reuse, Length, and Complexity.)

Step 3: Choose the Best Containment Step

Prompt:

Select the containment step that will leave potential evidence on the host uncompromised:

PIN code

FIDO security key

SMS authentication

OTP token

Containment step means “what security solution can you implement to protect employee accounts going forward, while preserving digital evidence on potentially compromised systems?”

The most secure solution for account protection among these, that also doesn’t interfere with host evidence, is FIDO security key.

Why?

PIN code: Not strong enough; also may be stored locally.

SMS authentication: Can be intercepted; often leaves traces on the host (like SMS logs).

OTP token: Similar risks, some implementations might log to the host.

FIDO security key: Hardware-based, phishing-resistant, no codes sent to the host, and doesn’t alter host evidence—authentication happens off the device.

So, the best answer is:

FIDO security key

Step 4: Solution Recap and Justification

Detailed Solution Recap:

Identify weak password practices:

Weaknesses: passwords are reused, not long enough, lack complexity, and used for a long time.

Select the best security solution:

Implement FIDO security keys for employees.

Most secure among listed options.

Hardware-based; resistant to phishing, interception, and does not leave evidence on the compromised host (which is important for forensics).

Impersonation occurs when an attacker or unauthorized user is granted access (authorized) by masquerading as a legitimate user, effectively bypassing or exploiting the authentication process. This means authorization is mistakenly granted before proper authentication.

Privilege escalation (A) involves gaining higher access after authentication. Race conditions (B) are timing vulnerabilities. Tailgating (C) refers to physical unauthorized access by following an authorized person.

Impersonation is a well-known identity attack vector detailed in the Threats and Vulnerabilities domain of SY0-701【6:Chapter 4†CompTIA Security+ Study Guide】.

Data classification is the process of assigning labels to data based on its sensitivity and business impact. Different organizations and sectors may have different data classification schemes, but a common one is the following1:

Public: Data that can be freely disclosed to anyone without any harm or risk.

Private: Data that is intended for internal use only and may cause some harm or risk if disclosed.

Confidential: Data that is intended for authorized use only and may cause significant harm or risk if disclosed.

Restricted: Data that is intended for very limited use only and may cause severe harm or risk if disclosed.

In this scenario, the company is developing a critical system for the government and storing project information on a fileshare. This data is likely to be classified as confidential and restricted, because it is not meant for public or private use, and it may cause serious damage to national security or public safety if disclosed. The government may also have specific requirements or regulations for handling such data, such as encryption, access control, and auditing2.

Endpoint management software is a tool that allows security engineers to monitor and control the configuration, security, and performance of workstations and servers from a central console. Endpoint management software can help detect and prevent unauthorized changes and software installations, enforce policies and compliance, and provide reports and alerts on the status of the endpoints. The other options are not as effective or comprehensive as endpoint management software for this purpose. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 137 1

The logs show an SQL injection attack. The first step is to verify if new accounts have been created, indicating a successful injection.

=================

 A geolocation policy is a policy that restricts or allows access to data or resources based on the geographic location of the user or device. A geolocation policy can be implemented using various methods, such as IP address filtering, GPS tracking, or geofencing. A geolocation policy can help the company’s legal department to prevent unauthorized access to sensitive documents from individuals in high-risk countries12.

The other options are not effective ways to limit access based on location:

Data masking: This is a technique of obscuring or replacing sensitive data with fictitious or anonymized data. Data masking can protect the privacy and confidentiality of data, but it does not prevent access to data based on location3.

Encryption: This is a process of transforming data into an unreadable format using a secret key or algorithm. Encryption can protect the integrity and confidentiality of data, but it does not prevent access to data based on location. Encryption can also be bypassed by attackers who have the decryption key or method4.

Data sovereignty regulation: This is a set of laws or rules that govern the storage, processing, and transfer of data within a specific jurisdiction or country. Data sovereignty regulation can affect the availability and compliance of data, but it does not prevent access to data based on location. Data sovereignty regulation can also vary depending on the country or region.

When new email servers are deployed, organizations must update their SPF (Sender Policy Framework) records to list the new servers as authorized senders. If the SPF DNS record does not include the new IP addresses, recipient mail systems cannot verify the legitimacy of the messages, causing them to be flagged as spam or rejected.

Security+ SY0-701 identifies SPF as a key email authentication mechanism responsible for preventing:

Email spoofing

Unauthorized sender impersonation

False spam detection

Domain reputation issues

CNAME (A) maps domain aliases but does not authenticate email. SMTP (B) is the mail protocol and does not influence spam classification. DLP (C) prevents data leakage, not spam filtering.

Updating the SPF record resolves legitimacy issues by informing receiving mail servers that the new email servers are trusted.

Thus, the correct answer is D: SPF.

Comprehensive and Detailed In-Depth Explanation:

AnEndpoint Detection and Response (EDR)solution is designed tomonitor, detect, and respond to security incidents on endpoints (such as workstations and servers). Itcollects and analyzes data, detecting suspicious activity and forwarding relevant information for further investigation.

Network Access Control (NAC) (A)enforces network access policies but does not analyze security threats on hosts.

Intrusion Prevention Systems (IPS) (B)detect and block network threats but do not provide deep endpoint analytics.

Security Information and Event Management (SIEM) (C)aggregates logs and provides security analytics but lacks direct endpoint detection and response capabilities.

EDR is the best choicefor analyzing and responding to endpoint security incidents.

An air-gapped system is physically isolated from unsecured networks (like the public Internet), ensuring that there is no direct or indirect network connection. This is the most effective way to prevent Internet-based access to sensitive systems.

Detailed Explanation:

Baseline enforcement ensures that all systems adhere to predefined security configurations, such as approved OS versions and patch levels, improving compliance and reducing vulnerabilities. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "System Baselines and Monitoring"​​.

A host-based firewall controls incoming and outgoing network traffic on a device by enforcing security rules, effectively blocking unwanted or insecure communications. It is specifically designed to protect the device from unauthorized access and malicious traffic.

System hardening (A) reduces vulnerabilities by disabling unnecessary services and patching but does not control communications dynamically. Intrusion detection systems (C) detect suspicious traffic but typically do not block it (unless paired with prevention). Anti-malware (D) protects against malicious software but not directly network communication filtering.

Host-based firewalls are a fundamental component of endpoint security highlighted in the Security Operations domain of SY0-701【6:Chapter 11†CompTIA Security+ Study Guide】.

An Intrusion Prevention System (IPS) is designed to automatically block or mitigate malicious network traffic in real time. Unlike an IDS, which only detects threats, an IPS performs inline traffic inspection and takes active action—such as dropping malicious packets, blocking connections, or updating firewall rules. This matches the requirement for an automated system that responds immediately to inbound threats.

Security+ SY0-701 highlights IPS as a preventive control that detects signature-based, anomaly-based, and behavioral threats, including exploits, malware, and command-and-control activity. IPS systems are essential in defending against fast-moving attacks where human response time is too slow.

UEM (A) manages endpoints but does not block inbound network threats.

WAF (C) protects web applications, not the entire network.

VPN (D) provides secure tunnels but does not prevent malicious inbound traffic.

Thus, B: IPS is the best solution for automatic threat blocking.

Detailed Explanation:Privileged Access Management (PAM) solutions enhance security by enforcing strong authentication, rotation of credentials, and access control for shared accounts. This is especially critical in scenarios like SSO failures. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Privileged Access and Identity Management"​​.

A tabletop exercise is a simulated scenario that tests the organization’s incident response plan and procedures. It involves key stakeholders and decision-makers who discuss their roles and actions in response to a hypothetical incident. It can help identify gaps, weaknesses, and improvement areas in the incident response process. It can also enhance communication, coordination, and collaboration among the participants. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 525 1

ACertificate Revocation List (CRL)is adigitally signed list maintained by a Certificate Authority (CA)that containsrevoked or expired certificates. This prevents clients from trustingcompromised or outdated certificates.

TPM (A)is a hardware security module, unrelated to certificate revocation.

PKI (C)is the overall system managing digital certificates, but it does not store revocation lists.

CSR (D)is a request to obtain a certificate, not to revoke one.

This describes a watering hole attack, where an attacker compromises a website frequently visited by the target group and delivers malicious payloads, such as automatic downloads.

XSS (A) injects scripts into web pages, typosquatting (C) involves fake websites with misspelled URLs, and buffer overflow (D) exploits memory but does not involve website compromise with automatic downloads.

Watering hole attacks are well-known web-based threats covered in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Detailed Explanation:Behavioral analytics tools monitor user actions and detect anomalies that may indicate insider threats, such as unauthorized access or unusual data exfiltration activities. These tools establish baselines for normal behavior and flag deviations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Behavioral Analytics and Monitoring"​​.

To block signature-based attacks, the Intrusion Prevention System (IPS) must be in active mode. In this mode, the IPS can actively monitor and block malicious traffic in real time based on predefined signatures. This is the best mode to prevent known attack types from reaching the internal network.

Monitor mode and sensor mode are typically passive, meaning they only observe and log traffic without actively blocking it.

Audit mode is used for review purposes and does not actively block traffic​​​.

To ensure that all systems requiring the patch are updated, the systems administrator must maintain an accurate asset inventory. This inventory lists all hardware and software assets within the organization, allowing the administrator to identify which systems are affected by the patch and ensuring that none are missed during the update process.

Network enumeration is used to discover devices on a network but doesn't track software that requires patching.

Data certification and procurement process are unrelated to tracking systems for patching purposes​​.
