CompTIA SY0-701 Dumps

Automatically generating WAF rules when applications are deployed is a hallmark of Infrastructure as Code (IaC). IaC allows infrastructure components—including firewalls, WAF policies, and load balancers—to be defined and deployed via code templates rather than manual configuration. In DevSecOps, IaC enables security controls to be embedded into deployment pipelines, ensuring that protections such as WAF rules are created instantly and consistently whenever new application versions are released.

Security+ SY0-701 highlights IaC as a method for automating infrastructure provisioning, standardizing security controls, and reducing configuration drift. This allows development and security teams to collaborate more effectively by treating security policies as code.

IoT (B) refers to smart devices, IoC (C) refers to indicators of compromise, and IaaS (D) refers to cloud compute infrastructure—not automated security policy creation.

Thus, the correct answer is A: IaC.

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.

Hardening access to a new database system requires implementing controls that restrict and secure how administrators and applications connect to the database. A jump server (A) is a hardened intermediary system used to manage access to sensitive systems such as databases. By forcing administrators to authenticate through a controlled, monitored jump host instead of connecting directly, organizations reduce attack surfaces and prevent unauthorized lateral movement. Security+ SY0-701 identifies jump servers as critical in securing high-value systems.

A host-based firewall (E) provides system-level traffic filtering directly on the database server. It allows only trusted IPs, ports, and services to communicate with the database, significantly reducing exposure. This is an essential hardening measure because databases should only accept connections from specific application servers or administrative hosts.

NIDS (B) monitors traffic but does not harden access. Monitoring (C) provides visibility but does not restrict access. A proxy server (D) is not typically used for database access. A WAF (F) protects web applications, not internal database systems.

Thus, A (Jump server) and E (Host-based firewall) are the correct hardening controls.

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.

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

Effective security governance requires clear assignment of roles and responsibilities, such as owners, controllers, and custodians, to ensure accountability for security-related tasks and data management within the organization. This establishes clear lines of responsibility and authority, which is fundamental to governance frameworks.

Detailed Explanation:A simulated failover tests the disaster recovery site's ability to handle a full transition of services. This ensures all systems can function as expected during an actual disaster. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Disaster Recovery and Business Continuity Planning"​​.

To ensure that sensitive data, such as Personally Identifiable Information (PII), is not modified, the bank should implement file integrity monitoring (FIM). FIM tracks changes to files and provides alerts if unauthorized modifications are detected, ensuring data integrity.

Full disk encryption protects data at rest but does not prevent or monitor modifications.

Network access control (NAC) manages access to the network but doesn't monitor file changes.

User behavior analytics (UBA) detects suspicious user activities but is not focused on file integrity​​​.

Detailed Explanation:

Retention policies dictate how long data must be stored to comply with local and international regulations. Non-compliance can result in legal and financial penalties. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Retention and Legal Requirements"​​.

Detailed Explanation:

Daily vulnerability scans help identify missing patches or updates across endpoints, allowing security teams to ensure compliance with patch management policies. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Vulnerability Management"​​.

A buffer overflow is a 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. A register is a small storage area in the CPU that holds temporary data or instructions. An attacker can exploit a buffer overflow to overwrite a register with a malicious address that points to a shellcode, which is a piece of code that gives the attacker control over the system. By doing so, the attacker can bypass the normal execution flow of the application and execute arbitrary commands.

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】.

An application allow list is a security technique that specifies which applications are permitted to run on a system or a network. An application allow list can block unknown programs from executing by only allowing the execution of programs that are explicitly authorized and verified. An application allow list can prevent malware, unauthorized software, or unwanted applications from running and compromising the security of the system or the network12.

The other options are not the best ways to block unknown programs from executing:

Access control list: This is a security technique that specifies which users or groups are granted or denied access to a resource or an object. An access control list can control the permissions and privileges of users or groups, but it does not directly block unknown programs from executing13.

Host-based firewall: This is a security device that monitors and filters the incoming and outgoing network traffic on a single host or system. A host-based firewall can block or allow networkconnections based on predefined rules, but it does not directly block unknown programs from executing1 .

DLP solution: This is a security system that detects and prevents the unauthorized transmission or leakage of sensitive data. A DLP solution can protect the confidentiality and integrity of data, but it does not directly block unknown programs from executing1 .

References = 1: CompTIA Security+ SY0-701 Certification Study Guide, page 972: Application Whitelisting – CompTIA Security+ SY0-701 – 3.5, video by Professor Messer3: CompTIA Security+ SY0-701 Certification Study Guide, page 98. : CompTIA Security+ SY0-701 Certification Study Guide, page 99. : CompTIA Security+ SY0-701 Certification Study Guide, page 100.

A version control tool, such as Git, is specifically designed to track changes in code, configuration scripts, IaC templates, and deployment files. In the context of creating new virtual servers—often built using Infrastructure as Code (IaC) or automated orchestration—version control allows teams to maintain historical records, compare changes, revert mistakes, ensure code integrity, and enable collaborative development.

Security+ SY0-701 emphasizes the use of version control in secure development practices to ensure traceability, accountability, and change visibility. It supports secure DevOps workflows by ensuring that no unauthorized or insecure code modifications are introduced into production environments.

A change management ticketing system (A) documents approval requests but does not track code-level modifications. A behavioral analyzer (B) evaluates anomalous behavior, not code changes. A collaboration platform (C) enables communication but lacks code versioning capability.

Therefore, the most appropriate tool is D: Version control tool.

Hashing is the process of converting plaintext passwords into a fixed-length, irreversible string using a mathematical algorithm (hash function). This makes each password unique based on its content, and even a small change in the password will produce a different hash. The primary purpose is to ensure that the actual passwords are not stored directly and cannot be easily recovered from the hash, even if the hash is compromised.

AES-256 is a symmetric encryption algorithm widely used to protect data at rest by converting plaintext into ciphertext that is unreadable without the proper key. It provides strong confidentiality and is a standard for encrypting stored data.

TLS 1.2 (A) secures data in transit, not at rest. Masking (C) obscures data but typically for display or limited use and is reversible. Salting (D) is used alongside hashing to protect passwords and data integrity but does not encrypt data.

Encryption with AES-256 is recognized as a best practice for securing stored data in the Security+ Cryptography and General Security Concepts domains【6:Chapter 7†CompTIA Security+ Study Guide】.

To identify the impacted host in a command-and-control (C2) server incident, the following logs should be analyzed:

DHCP logs: These logs record IP address assignments. By reviewing DHCP logs, an organization can determine which host was assigned a specific IP address during the time of the attack.

Firewall logs: Firewall logs will show traffic patterns, including connections to external C2 servers. Analyzing these logs helps to identify the IP address and port numbers of the communicating host.

Application, Authentication, and Database logs are less relevant in this context because they focus on internal processes and authentication events rather than network traffic involved in a C2 attack​​​.

Detailed Explanation:Standard operating procedures (SOPs) outline the steps to be followed to maintain a secure baseline, such as testing and deploying patches while minimizing risk to the system. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Patch Management and Baseline Compliance"​​.

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.

Group policies can inadvertently introduce misconfigurations, such as enabling insecure settings or failing to disable legacy protocols, increasing vulnerabilities.

Zero-day (B) are previously unknown vulnerabilities, malicious updates (C) are attacker-controlled, and supply chain (D) risks come from third-party components.

Misconfiguration vulnerabilities are commonly introduced during changes and are emphasized in Security Operations【6:Chapter 14†CompTIA Security+ Study Guide】.

Change management procedures provide structured steps to approve, test, document, and deploy software changes, ensuring controlled and auditable version releases that minimize risks and disruptions.

Business continuity planning (A) relates to operational continuity, quantified risk analysis (B) assesses risks quantitatively, and static code analysis (C) finds coding defects but does not control release processes.

Change management is fundamental to software lifecycle governance in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Preparation is the phase in the incident response process when a security analyst reviews roles and responsibilities, as well as the policies and procedures for handling incidents. Preparation also involves gathering and maintaining the necessary tools, resources, and contacts for responding to incidents. Preparation can help a security analyst to be ready and proactive when an incident occurs, as well as to reduce the impact and duration of the incident.

Some of the activities that a security analyst performs during the preparation phase are:

Defining the roles and responsibilities of the incident response team members, such as the incident manager, the incident coordinator, the technical lead, the communications lead, and the legal advisor.

Establishing the incident response plan, which outlines the objectives, scope, authority, and procedures for responding to incidents, as well as the escalation and reporting mechanisms.

Developing the incident response policy, which defines the types and categories of incidents, the severity levels, the notification and reporting requirements, and the roles and responsibilities of the stakeholders.

Creating the incident response playbook, which provides the step-by-step guidance and checklists for handling specific types of incidents, such as denial-of-service, ransomware, phishing, or data breach.

Acquiring and testing the incident response tools, such as network and host-based scanners, malware analysis tools, forensic tools, backup and recovery tools, and communication and collaboration tools.

Identifying and securing the incident response resources, such as the incident response team, the incident response location, the evidence storage, and the external support.

Building and maintaining the incident response contacts, such as the internal and external stakeholders, the law enforcement agencies, the regulatory bodies, and the media.

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.

The scenario suggests that only the employees who used the kiosks inside the building had their credentials compromised. Since the time-keeping website is accessible from the internet, it is possible that a malicious actor exploited an unpatched vulnerability in the site, allowing them to inject malicious code that captured the credentials of those who logged in from the kiosks. This is a common attack vector for stealing credentials from web applications.

A Cybersecurity Framework (CSF) provides a structured approach to standardizing and aligning security programs across different organizations. By both companies adopting the same CSF, they can ensure that their security measures, policies, and practices are consistent, which is essential during a merger when aligning two different security programs.

Metadata is data that describes other data, such as its format, origin, creation date, author, and other attributes. Video files, like other types of files, can contain metadata that can provide useful information for forensic analysis. For example, metadata can reveal the camera model, location, date and time, and software used to create or edit the video file. To query the file’s metadata, a security analyst can use various tools, such as MediaInfo1, ffprobe2, or hexdump3, to extract anddisplay the metadata from the video file. By querying the file’s metadata, the security analyst can most likely identify both the creation date and the file’s creator, as well as other relevant information. Obtaining the file’s SHA-256 hash, checking endpoint logs, or using hexdump on the file’s contents are other possible actions, but they are not the most appropriate to answer the question. The file’s SHA-256 hash is a cryptographic value that can be used to verify the integrity or uniqueness of the file, but it does not reveal any information about the file’s creation date or creator. Checking endpoint logs can provide some clues about the file’s origin or activity, but it may not be reliable or accurate, especially if the logs are tampered with or incomplete. Using hexdump on the file’s contents can show the raw binary data of the file, but it may not be easy or feasible to interpret the metadata from the hex output, especially if the file is large or encrypted. References: 1: How do I get the meta-data of a video file? 2: How to check if an mp4 file contains malware? 3: [Hexdump - Wikipedia]

Memory injection vulnerabilities allow unauthorized code or commands to be executed within a software program, leading to abnormal behavior such as generating outbound traffic over random high ports. This issue often arises from software not properly validating or encoding input, which can be exploited by attackers to inject malicious code.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

Packet capture data can be very large and may not need to be stored for extended periods compared to other logs essential for security audits.

 A cold site is a type of backup data center that has the necessary infrastructure to support IT operations, but does not have any pre-configured hardware or software. A cold site is the cheapest option among the backup data center types, but it also has the longest recovery time objective (RTO) and recovery point objective (RPO) values. A cold site is suitable for scenarios where the cost-benefit is the primary requirement and the RTO and RPO values are not very stringent. A cold site can take up to two days or more to restore the normal operations after a disaster. References = CompTIA Security+ SY0-701 Certification Study Guide, page 387; Backup Types – SY0-601 CompTIA Security+ : 2.5, video at 4:50.

 An acceptable use policy (AUP) is a set of rules that govern how users can access and use a corporate network or the internet. The AUP helps companies minimize their exposure to cyber security threats and limit other risks. The AUP also serves as a notice to users about what they are not allowed to do and protects the company against misuse of their network. Users usually have to acknowledge that they understand and agree to the rules before accessing the network1.

An AUP best represents a preventive security control type, because it aims to deter or stop potential security incidents from occurring in the first place. A preventive control is proactive and anticipates possible threats and vulnerabilities, and implements measures to prevent themfrom exploiting or harming the system or the data. A preventive control can be physical, technical, or administrative in nature2.

Some examples of preventive controls are:

Locks, fences, or guards that prevent unauthorized physical access to a facility or a device

Firewalls, antivirus software, or encryption that prevent unauthorized logical access to a network or a system

Policies, procedures, or training that prevent unauthorized or inappropriate actions or behaviors by users or employees

An AUP is an example of an administrative preventive control, because it defines the policies and procedures that users must follow to ensure the security and proper use of the network and the IT resources. An AUP can prevent users from engaging in activities that could compromise the security, performance, or availability of the network or the system, such as:

Downloading or installing unauthorized or malicious software

Accessing or sharing sensitive or confidential information without authorization or encryption

Using the network or the system for personal, illegal, or unethical purposes

Bypassing or disabling security controls or mechanisms

Connecting unsecured or unapproved devices to the network

By enforcing an AUP, a company can prevent or reduce the likelihood of security breaches, data loss, legal liability, or reputational damage caused by user actions or inactions3.

Segmentation is a technique that divides a network into smaller subnetworks or segments, each with its own security policies and controls. Segmentation can help mitigate network access vulnerabilities in legacy loT devices by isolating them from other devices and systems, reducing their attack surface and limiting the potential impact of a breach. Segmentation can also improve network performance and efficiency by reducing congestion and traffic. Patching, insurance, and replacement are other possible strategies to deal with network access vulnerabilities, but they may not be feasible or effective in the short term. Patching may not be available or compatible for legacy loT devices, insurance may not cover the costs or damages of a cyberattack, and replacement may be expensive and time-consuming. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 142-143

 Sanitization is the process of removing sensitive data from a storage device or a system before it is disposed of or reused. Sanitization can be done by using software tools or hardware devices that overwrite the data with random patterns or zeros, making it unrecoverable. Sanitization is different from destruction, which is the physical damage of the storage device to render it unusable. Sanitization is also different from enumeration, which is the identification of network resources or devices, and inventory, which is the tracking of assets and their locations. The policy of securely wiping hard drives before sending decommissioned systems to recycling is an example of sanitization, as it ensures that no confidential data can be retrieved from the recycled devices. References = Secure Data Destruction – SY0-601 CompTIA Security+ : 2.7, video at 1:00; CompTIA Security+ SY0-701 Certification Study Guide, page 387.

A training curriculum plan for a security awareness program should address the following factors:

The threat vectors based on the industry in which the organization operates. This will help the employees to understand the specific risks and challenges that their organization faces, and how to protect themselves and the organization from cyberattacks. For example, a healthcareorganization may face different threat vectors than a financial organization, such as ransomware, data breaches, or medical device hacking1.

The cadence and duration of training events. This will help the employees to retain the information and skills they learn, and to keep up with the changing security landscape. The training events should be frequent enough to reinforce the key concepts and behaviors, but not too long or too short to lose the attention or interest of the employees. For example, a security awareness program may include monthly newsletters, quarterly webinars, annual workshops, or periodic quizzes2.

OCSP stands for Online Certificate Status Protocol. It is a protocol that allows applications to check the revocation status of a certificate in real-time. It works by sending a query to an OCSP responder, which is a server that maintains a database of revoked certificates. The OCSP responder returns a response that indicates whether the certificate is valid, revoked, or unknown. OCSP is faster and more efficient than downloading and parsing Certificate Revocation Lists (CRLs), which are large files that contain the serial numbers of all revoked certificates issued by a Certificate Authority (CA). References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 337 1

A Certificate Signing Request (CSR) is a request sent to a certificate authority (CA) to issue an SSL certificate. The CSR contains information like the public key, which will be part of the certificate.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.

Intellectual property is a type of data that consists of ideas, inventions, designs, or other creative works that have commercial value and are protected by law. Employees in the research and development business unit are most likely to use intellectual property data in their day-to-day work activities, as they are involved in creating new products or services for the company. Intellectual property data needs to be protected from unauthorized use, disclosure, or theft, as it can give the company a competitive advantage in the market. Therefore, these employees receive extensive training to ensure they understand how to best protect this type of data. References = CompTIA Security+ SY0-701 Certification Study Guide, page 90; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 1.2 - Security Concepts, 7:57 - 9:03.

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.

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.

References = 

When a zero-day vulnerability is discovered in mission-critical systems that require high availability, immediate patching is often not possible due to lack of available patches or the risk of disrupting critical operations. In such cases, the best practice is to implement compensating controls (such as increased monitoring, access controls, network segmentation, or web application firewalls) to mitigate risk until a patch or permanent solution can be safely applied.

A disaster recovery plan (DRP) is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. A DRP typically includes the following elements:

A risk assessment that identifies the potential threats and impacts to the organization’s critical assets and processes.

A business impact analysis that prioritizes the recovery of the most essential functions and data.

A recovery strategy that defines the roles and responsibilities of the recovery team, the resources and tools needed, and the steps to follow to restore the system.

A testing and maintenance plan that ensures the DRP is updated and validated regularly. A DRP is required for an organization to properly manage its restore process in the event of system failure, as it provides a clear and structured framework for recovering from a disaster and minimizing the downtime and data loss. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325.

Encryption is a method of transforming data in a way that makes it unreadable without a secret key necessary to decrypt the data back into plaintext. Encryption is one of the most common and effective ways to protect data at rest, as it prevents unauthorized access, modification, or theft of the data. Encryption can be applied to different types of data at rest, such as block storage, object storage, databases, archives, and so on. Hashing, tokenization, and segmentation are not methods of rendering data at rest unreadable, but rather of protecting data in other ways. Hashing is a one-way function that generates a fixed-length output, called a hash or digest, from an input, such that the input cannot be recovered from the output. Hashing is used to verify the integrity and authenticity of data, but not to encrypt it. Tokenization is a process that replaces sensitive data with non-sensitive substitutes, called tokens, that have no meaning or value on their own. Tokenization is used to reduce the exposure and compliance scope of sensitive data, but not to encrypt it. Segmentation is a technique that divides a network or a system into smaller, isolated units, called segments, that have different levels of access and security. Segmentation is used to limit the attack surface and contain the impact of a breach, but not to encrypt data at rest. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, pages 77-781; Protecting data at rest - Security Pillar3

A warm site offers a compromise between cost and recovery speed. It includes hardware and network infrastructure partially configured, allowing quicker recovery than a cold site but at lower cost than a hot site.

Hot sites (A) enable rapid recovery but at high cost. Cold sites (B) are low cost but slow to recover. Manual (C) refers to manual processes, typically slower.

Warm sites balance recovery time and cost in disaster recovery planning【6:Chapter 9†CompTIA Security+ Study Guide】.

Multifactor authentication (MFA) requires users to provide two or more of the following categories:

Something you know (password/PIN)

Something you have (token/smart card)

Something you are (biometrics)

Authentication tokens (A) qualify as something you have, such as hardware tokens, OTP apps, or smart cards.

Biometrics (C) qualify as something you are, such as fingerprint scans, facial recognition, or iris scans. Using these two together easily establishes MFA.

Least privilege (B) is an authorization principle, not an MFA factor. LDAP (D) is a directory service protocol, not an MFA mechanism. Password vaulting (E) assists with credential storage but does not implement MFA. SAML (F) is a federation protocol used for Single Sign-On (SSO), not inherently MFA.

Thus, the correct MFA components are A: Authentication tokens and C: Biometrics.

When addressing the risk of supply chain compromise (such as the introduction of malicious hardware or firmware during procurement), the acquisition process should be reviewed first. Ensuring that the process for purchasing, inspecting, and validating new equipment includes appropriate vendor vetting and secure handling practices is the first step in mitigating supply chain risks.

Input validation (D)is the most effective way to preventinjection attacks, such asSQL injection, XSS, etc. It ensures that only correctly formatted and expected inputs are processed by the application.

This is clearly identified underDomain 2.3: Application security techniques, whereinput validationis listed as aprimary defense against injection attacks.

Benchmarks provide standardized security configuration baselines or templates (such as CIS Benchmarks) for systems including firewalls. Using benchmarks helps MSSPs apply consistent and secure configurations across many clients efficiently.

SNMP (A) is for network device management, Netflow (C) is for traffic analysis, and SCAP (D) is a framework for vulnerability and compliance management but not directly for template creation.

Benchmarks are fundamental for configuration management in Security Operations【6:Chapter 14†CompTIA Security+ Study Guide】.

A change management procedure is a set of steps and guidelines that a security administrator should adhere to when setting up a new set of firewall rules. A firewall is a device or software that can filter, block, or allow network traffic based on predefined rules or policies. A firewall rule is a statement that defines the criteria and action for a firewall to apply to a packet or a connection. For example, a firewall rule can allow or deny traffic based on the source and destination IP addresses, ports, protocols, or applications. Setting up a new set of firewall rules is a type of change that can affect the security, performance, and functionality of the network. Therefore, a change management procedure is necessary to ensure that the change is planned, tested, approved, implemented, documented, and reviewed in a controlled and consistent manner. A change management procedure typically includes the following elements:

A change request that describes the purpose, scope, impact, and benefits of the change, as well as the roles and responsibilities of the change owner, implementer, and approver.

A change assessment that evaluates the feasibility, risks, costs, and dependencies of the change, as well as the alternatives and contingency plans.

A change approval that authorizes the change to proceed to the implementation stage, based on the criteria and thresholds defined by the change policy.

A change implementation that executes the change according to the plan and schedule, and verifies the results and outcomes of the change.

A change documentation that records the details and status of the change, as well as the lessons learned and best practices.

A change review that monitors and measures the performance and effectiveness of the change, and identifies any issues or gaps that need to be addressed or improved.

A change management procedure is important for a security administrator to adhere to when setting up a new set of firewall rules, as it can help to achieve the following objectives:

Enhance the security posture and compliance of the network by ensuring that the firewall rules are aligned with the security policies and standards, and that they do not introduce any vulnerabilities or conflicts.

Minimize the disruption and downtime of the network by ensuring that the firewall rules are tested and validated before deployment, and that they do not affect the availability or functionality of the network services or applications.

Improve the efficiency and quality of the network by ensuring that the firewall rules are optimized and updated according to the changing needs and demands of the network users and stakeholders, and that they do not cause any performance or compatibility issues.

Increase the accountability and transparency of the network by ensuring that the firewall rules are documented and reviewed regularly, and that they are traceable and auditable by the relevant authorities and parties.

The other options are not correct because they are not related to the process of setting up a new set of firewall rules. A disaster recovery plan is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. An incident response procedure is a set of steps and guidelines that aim to contain, analyze, eradicate, and recover from a security incident, such as a cyberattack, data breach, or malware infection. A business continuity plan is a set of strategies and actions that aim to maintain the essential functions and operations of an organization during and after a disruptive event, such as a pandemic, power outage, or civil unrest. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 1.3: Security Operations, video: Change Management (5:45).

 A user provisioning script is an automation technique that uses a predefined set of instructions or commands to create, modify, or delete user accounts and assign appropriate access or permissions. A user provisioning script can help to streamline account creation by reducing manual errors, ensuring consistency and compliance, and saving time and resources12.

The other options are not automation techniques that can streamline account creation:

Guard rail script: This is a script that monitors and enforces the security policies and rules on a system or a network. A guard rail script can help to prevent unauthorized or malicious actions, such as changing security settings, accessing restricted resources, or installing unwanted software3.

Ticketing workflow: This is a process that tracks and manages the requests, issues, or incidents that are reported by users or customers. A ticketing workflow can help to improve the communication, collaboration, and resolution of problems, but it does not automate the account creation process4.

Escalation script: This is a script that triggers an alert or a notification when a certain condition or threshold is met or exceeded. An escalation script can help to inform the relevant parties or authorities of a critical situation, such as a security breach, a performance degradation, or a service outage.

 Password spraying is a type of brute force attack that tries common passwords across several accounts to find a match. It is a mass trial-and-error approach that can bypass account lockout protocols. It can give hackers access to personal or business accounts and information. It is not a targeted attack, but a high-volume attack tactic that uses a dictionary or a list of popular or weak passwords12.

The logs show that the attacker is using the same password ("password123") to attempt to log in to different accounts ("admin", "user1", "user2", etc.) on the same web server. This is a typical pattern of password spraying, as the attacker is hoping that at least one of the accounts has a weak password that matches the one they are trying. The attacker is also using a tool called Hydra, which is one of the most popular brute force tools, often used in cracking passwords for network authentication3.

Account forgery is not the correct answer, because it involves creating fake accounts or credentials to impersonate legitimate users or entities. There is no evidence of account forgery in the logs, as the attacker is not creating any new accounts or using forged credentials.

Pass-the-hash is not the correct answer, because it involves stealing a hashed user credential and using it to create a new authenticated session on the same network. Pass-the-hash does not require the attacker to know or crack the password, as they use the stored version of the password to initiate a new session4. The logs show that the attacker is using plain text passwords, not hashes, to try to log in to the web server.

Brute-force is not the correct answer, because it is a broader term that encompasses different types of attacks that involve trying different variations of symbols or words until the correct password is found. Password spraying is a specific type of brute force attack that uses a single common password against multiple accounts5. The logs show that the attacker is using password spraying, not brute force in general, to try to gain access to the web server. References = 1: Password spraying: An overview of password spraying attacks … - Norton, 2: Security: Credential Stuffing vs. Password Spraying - Baeldung, 3: Brute ForceAttack: A definition + 6 types to know | Norton, 4: What is a Pass-the-Hash Attack? - CrowdStrike, 5: What is a Brute Force Attack? | Definition, Types & How It Works - Fortinet

A tabletop exercise is a simulation-based activity where incident response team members and relevant stakeholders walk through a hypothetical security incident in a discussion-based format. This exercise helps validate response plans, roles, and communication channels without actual system disruption.

Lessons learned (A) is a post-incident review, digital forensics (B) is evidence collection after an incident, and root cause analysis (D) investigates the underlying cause after an event.

Tabletop exercises are standard practices within the Security Operations domain to prepare teams for real incidents【6:Chapter 14†CompTIA Security+ Study Guide】.

Risk appetiterefers to thelevel of risk an organization is willing to acceptbefore implementing security measures. When expanding access controls, the company must assess how much risk is acceptable in terms ofdata exposure, unauthorized access, and compliance obligations.

Software-defined networking (SDN) enables microsegmentation by allowing administrators to create fine-grained, dynamic network segments at the software layer independent of physical network topology. This capability isolates workloads and controls traffic flows between segments, enhancing security within data centers and cloud environments.

Next-generation firewalls (A) provide advanced filtering and inspection but do not inherently deliver the granular segmentation flexibility of SDN. Embedded systems (C) and air-gapped systems (D) refer to specific hardware or physical isolation techniques but do not implement microsegmentation as a network control method.

The concept of microsegmentation through SDN is detailed in the Security Architecture domain of the SY0-701 exam【6:Chapter 3†CompTIA Security+ Study Guide】.

Improving security awareness training directly addresses user behavior by teaching employees how to better recognize legitimate emails versus actual phishing attempts. Enhanced training can reduce the number of false positives by helping users more accurately identify true phishing attempts, lowering unnecessary reports and thus help desk workload.

A hot site is a fully operational offsite facility that is equipped with hardware, software, and up-to-date data, and is ready to take over operations immediately if the primary site fails. This allows for minimal downtime and quick failover, meeting the requirement for rapid recovery.

Classification is the process of assigning a level of sensitivity and handling requirements to data, which informs its lifecycle management, retention, and disposal methods. In regulated industries such as banking, proper data classification ensures that data subject to legal or regulatory requirements is destroyed according to those requirements at the end of its retention period. This directly guides how the data should be handled and disposed of.

The employee notices that the links in the email do not correspond to the company's official URLs, indicating that this is likely a social engineering attack. Social engineering involves manipulating individuals into divulging confidential information or performing actions that may compromise security. Phishing emails, like the one described, often contain fraudulent links to trick the recipient into providing sensitive information or downloading malware.

Business email refers to business email compromise (BEC), which typically involves impersonating a high-level executive to defraud the company.

Unsecured network is unrelated to the email content.

Default credentials do not apply here, as the issue is with suspicious links, not login credentials​​.

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.

Secure Real-Time Transport Protocol (SRTP) is a security protocol used to encrypt and authenticate the streaming of audio and video over IP networks. It ensures that the video streams from the IP cameras are both encrypted to prevent unauthorized access and authenticated to verify the integrity of the stream, making it the ideal choice for securing video surveillance.

VM escape is a vulnerability where an attacker breaks out of a virtual machine guest environment to access the host hypervisor, gaining control over other guests or the host system itself.

Cross-site scripting (A) and SQL injection (B) are application-layer attacks. Race condition (C) is a timing-related vulnerability.

VM escape is a critical threat in virtualized environments discussed under Threats and Vulnerabilities in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

SQL injection is a type of attack that exploits a database misconfiguration or a flaw in the application code that interacts with the database. An attacker can inject malicious SQL statements into the user input fields or the URL parameters that are sent to the database server. These statements can then execute unauthorized commands, such as reading, modifying, deleting, or creating data, or even taking over the database server. SQL injection can compromise the confidentiality, integrity, and availability of the data and the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215 1

Confidentiality is the security concept that ensures data is protected from unauthorized access or disclosure. The principle of least privilege is a technique that grants users or systems the minimum level of access or permissions that they need to perform their tasks, and nothing more. By applying the principle of least privilege to a human resources fileshare, the permissions can be restricted to only those who have a legitimate need to access the sensitive data, such as HR staff, managers, or auditors. This can prevent unauthorized users, such as hackers, employees, or contractors, from accessing, copying, modifying, or deleting the data. Therefore, the principle of least privilege can enhance the confidentiality of the data on the fileshare. Integrity, availability, and non-repudiation are other security concepts, but they are not the best reason for permissions on a human resources fileshare to follow the principle of least privilege. Integrity is the security concept that ensures data is accurate and consistent, and protected from unauthorized modification or corruption. Availability is the security concept that ensures data is accessible and usable by authorized users or systems when needed. Non-repudiation is the security concept that ensures the authenticity and accountability of data and actions, and prevents the denial of involvement or responsibility. While these concepts are also important for data security, they are not directly related to the level of access or permissions granted to users or systems. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 16-17, 372-373

Change management is the formal process designed to control, document, approve, and track modifications to systems, internal processes, assets, and security controls. This control mechanism helps prevent unauthorized or unintended changes that could introduce vulnerabilities or disrupt operations.

Playbooks are documented procedures for responding to incidents, incident response manages security incidents, and acceptable use policies define acceptable user behavior but do not directly control changes.

By enforcing proper change management, organizations maintain the integrity and security of their infrastructure, which is a critical topic covered in the Security Program Management and Oversight domain of SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】

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.

To mitigate the risk of sensitive data being exfiltrated from the environment, the IT manager should implement a Data Loss Prevention (DLP) solution. DLP monitors and controls the movement of sensitive data, ensuring that unauthorized transfers are blocked and potential data breaches are prevented.

XDR (Extended Detection and Response) is useful for threat detection across multiple environments but doesn't specifically address data exfiltration.

SPF (Sender Policy Framework) helps prevent email spoofing, not data exfiltration.

DMARC (Domain-based Message Authentication, Reporting & Conformance) also addresses email security and spoofing, not data exfiltration​​.

Comprehensive and Detailed In-Depth Explanation:

Operating system (OS) vulnerabilitiescan allow attackers to exploit system functions that affect multiple applications, leading towidespread compromise.

B (patch cycle concerns)is valid but not the primary concern—many OS vendors provide regular patches.

C (user trust in OS features)is a risk, but the more significant issue is thatOS vulnerabilities often affect multiple system components.

D (ease of exploitation)is not always true, as application and human-related vulnerabilities can be equally exploitable.

Thus,the main concern is that an OS exploit can impact multiple system functions, leading to broader security risks.

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.

An air gap is the practice of physically isolating a secure network from any external or unsecured networks, effectively preventing any external communication or data leakage. It is the strongest method to prevent data exfiltration in sensitive environments.

Containerization (B) and virtualization (C) are technologies for isolating applications or systems logically but do not guarantee physical separation. Decentralization (D) distributes resources but doesn’t prevent data leakage.

Air gaps are critical in highly secure environments and covered under Resilience and Physical Security in SY0-701【6:Chapter 9†CompTIA Security+ Study Guide】.

Infrastructure as Code (IaC)enables automated provisioning and configuration of infrastructure, making environmentsrepeatable, consistent, and scalable. The ability tobetter manage and replicate configurations (B)ensures that security settings are not missed and reduces misconfigurations.

According to theCompTIA Security+ SY0-701exam objectives underDomain 4.1 (Explain the security implications of different architecture models),IaCprovides the ability to"automatically enforce security controls"and manageconsistent configuration states, reducing human error.

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.

Wiping involves securely erasing data by overwriting the hard drive, ensuring the information is unrecoverable. It is cost-effective compared to physical destruction methods like shredding.

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

Acknowledgement and attestationinvolveformal confirmationthat an application is no longer in scope for compliance, auditing, or reporting requirements. This typically includes documentation signed by relevant stakeholders confirming that the software no longer processes, stores, or transmits relevant data.

Data inventory and retention (A)is related to managing data assets, not software scope confirmation.

Right to be forgotten (B)pertains toprivacy laws (e.g., GDPR), allowing individuals to request data deletion.

Due care and due diligence (C)focus on security best practices rather than software applicability.

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"​​.

The correct answer is C. Password, authentication token, thumbprint. This combination of authentication factors satisfies the manager’s goal of implementing multifactor authentication that uses something you know, something you have, and something you are.

Something you know is a type of authentication factor that relies on the user’s knowledge of a secret or personal information, such as a password, a PIN, or a security question. A password is a common example of something you know that can be used to access a VPN12

Something you have is a type of authentication factor that relies on the user’s possession of a physical object or device, such as a smart card, a token, or a smartphone. An authentication token is a common example of something you have that can be used to generate a one-time password (OTP) or a code that can be used to access a VPN12

Something you are is a type of authentication factor that relies on the user’s biometric characteristics, such as a fingerprint, a face, or an iris. A thumbprint is a common example of something you are that can be used to scan and verify the user’s identity to access a VPN12

Purple is the team that combines both offensive and defensive testing techniques to protect an organization’s critical systems. Purple is not a separate team, but rather a collaboration between the red team and the blue team. The red team is the offensive team that simulates attacks and exploits vulnerabilities in the organization’s systems. The blue team is the defensive team that monitors and protects the organization’s systems from real and simulated threats. The purple team exists to ensure and maximize the effectiveness of the red and blue teams by integrating the defensive tactics and controls from the blue team with the threats and vulnerabilities found by the red team into a single narrative that improves the overall security posture of the organization. Red, blue, and yellow are other types of teams involved in security testing, but they do not combine both offensive and defensive techniques. The yellow team is the team that builds software solutions, scripts, and other programs that the blue team uses in the security testing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1331; Penetration Testing: Understanding Red, Blue, & Purple Teams3

The right to be forgotten refers to an individual’s legal right, under regulations such as GDPR, to request the deletion of all personal data held about them by an organization. This gives individuals control over their digital footprint and privacy.

After completing a vulnerability assessment and remediating the identified vulnerabilities, the next step is to rescan the network to verify that the vulnerabilities have been successfully fixed and no new vulnerabilities have been introduced. A vulnerability assessment is a process of identifying and evaluating the weaknesses and exposures in a network, system, or application that could be exploited by attackers. A vulnerability assessment typically involves using automated tools, such as scanners, to scan the network and generate a report of the findings. The report may include information such as the severity, impact, and remediation of the vulnerabilities. The operations team is responsible for applying the appropriate patches, updates, or configurations to address the vulnerabilities and reduce the risk to the network. A rescan is necessary to confirm that the remediation actions have been effective and that the network is secure.

Conducting an audit, initiating a penetration test, or submitting a report are not the next steps after completing a vulnerability assessment and remediating the vulnerabilities. An audit is a process of reviewing and verifying the compliance of the network with the established policies, standards, and regulations. An audit may be performed by internal or external auditors, and it may use the results of the vulnerability assessment as part of the evidence. However, an audit is not a mandatory step after a vulnerability assessment, and it does not validate the effectiveness of the remediation actions.

A penetration test is a process of simulating a real-world attack on the network to test the security defenses and identify any gaps or weaknesses. A penetration test may use the results of the vulnerability assessment as a starting point, but it goes beyond scanning and involves exploiting the vulnerabilities to gain access or cause damage. A penetration test may be performed after a vulnerability assessment, but only with the proper authorization, scope, and rules of engagement. A penetration test is not a substitute for a rescan, as it does not verify that the vulnerabilities have been fixed.

Submitting a report is a step that is done after the vulnerability assessment, but before the remediation. The report is a document that summarizes the findings and recommendations of the vulnerability assessment, and it is used to communicate the results to the stakeholders and the operations team. The report may also include a follow-up plan and a timeline for the remediation actions. However, submitting a report is not the final step after the remediation, as it does not confirm that the network is secure.

An Acceptable Use Policy (AUP) defines what users are permitted and prohibited from doing on an organization's systems, including website access. Accessing unauthorized sites is a common violation of the AUP.

Comprehensive and Detailed In-Depth Explanation:

Input validationensures that only properly formatted and expected input is accepted by an application,preventing injection attacks such as SQL injection and command injection. Properly validating and sanitizing user inputs can mitigate these types of attacks.

Authentication (A)helps verify user identity but does not prevent injection attacks.

Secure cookies (B)protect session data but do not stop injection-based exploits.

Static code analysis (C)can help identify vulnerabilities but does not activelypreventinjection attacks in real-time.

Implementingstrong input validationcanprevent malicious code from being executed, reducing the risk of injection attacks.

The presence of another device providing internet access that bypasses the content filtering system indicates the existence of a rogue access point. Rogue access points are unauthorized devices that can create a backdoor into the network, allowing users to bypass security controls like content filtering. This presents a significant security risk as it can expose the network to unauthorized access and potential data breaches.

References =

CompTIA Security+ SY0-701 Course Content: Rogue access points are highlighted as a major security risk, allowing unauthorized access to the network and bypassing security measures​​.

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 =

Application allow listing is the most effective technique to prevent bloatware, unauthorized software, or unnecessary applications from running on devices. Allow lists work by permitting only pre-approved, trusted applications to execute, blocking everything else by default. This is a recommended best practice in Security+ SY0-701 for reducing attack surface, preventing malware, and maintaining lean, hardened system images.

Bloatware often comes pre-installed on devices or is unintentionally installed by users. An allow list ensures only authorized applications required for business functions can run, thereby eliminating bloatware risks.

Disabling ports/protocols (A) hardens network access but does not prevent software installation. Default password changes (C) improve authentication security but are unrelated to software control. Access control permissions (D) restrict who can access what but do not prevent installation of unnecessary apps.

Thus, the correct answer is B: Application allow list.

Rules of engagement are the detailed guidelines and constraints regarding the execution of information security testing, such as penetration testing. They define the scope, objectives, methods, and boundaries of the test, as well as the roles and responsibilities of the testers and the clients. Rules of engagement help to ensure that the test is conducted in a legal, ethical, and professional manner, and that the results are accurate and reliable. Rules of engagement typically include the following elements:

The type and scope of the test, such as black box, white box, or gray box, and the target systems, networks, applications, or data.

The client contact details and the communication channels for reporting issues, incidents, or emergencies during the test.

The testing team credentials and the authorized tools and techniques that they can use.

The sensitive data handling and encryption requirements, such as how to store, transmit, or dispose of any data obtained during the test.

The status meeting and report schedules, formats, and recipients, as well as the confidentiality and non-disclosure agreements for the test results.

The timeline and duration of the test, and the hours of operation and testing windows.

The professional and ethical behavior expectations for the testers, such as avoiding unnecessary damage, disruption, or disclosure of information.

Supply chain analysis, right to audit clause, and due diligence are not related to the terms of a test with a third-party penetration tester. Supply chain analysis is the process of evaluating the security and risk posture of the suppliers and partners in a business network. Right to audit clause is a provision in a contract that gives one party the right to audit another party to verify their compliance with the contract terms and conditions. Due diligence is the process of identifying and addressing the cyber risks that a potential vendor or partner brings to an organization.

Availability is the ability of a system or service to be accessible and usable when needed. For a web application that allows individuals to digitally report health emergencies, availability is the most important consideration during development, because any downtime or delay could have serious consequences for the health and safety of the users. The web application should be designed to handle high traffic, prevent denial-of-service attacks, and have backup and recovery plans in case of failures2.

 A business email compromise (BEC) attack is a type of phishing attack that targets employees who have access to company funds or sensitive information. The attacker impersonates a trusted person, such as an executive, a vendor, or a client, and requests a fraudulent payment, a wire transfer, or confidential data. The attacker often uses social engineering techniques, such as urgency, pressure, or familiarity, to convince the victim to comply with the request12.

In this scenario, option A describes a possible BEC attack, where an employee receives a gift card request in an email that has an executive’s name in the display field of the email. The email may look like it is coming from the executive, but the actual email address may be spoofed or compromised. The attacker may claim that the gift cards are needed for a business purpose, such as rewarding employees or clients, and ask the employee to purchase them and send the codes. This is a common tactic used by BEC attackers to steal money from unsuspecting victims34.

Option B describes a possible ransomware attack, where malicious software encrypts the files on a device and demands a ransom for the decryption key. Option C describes a possible credential harvesting attack, where an attacker tries to obtain the login information of a privileged account by posing as a legitimate authority. Option D describes a possible phishing attack, where an attacker tries to lure the victim to a fake website that mimics the company’s email portal and capture their credentials. These are all types of cyberattacks, but they are not examples of BEC attacks. References = 1: Business Email Compromise - CompTIA Security+ SY0-701 - 2.2 2: CompTIA Security+ SY0-701 Certification Study Guide 3: Business Email Compromise: The 12 Billion Dollar Scam 4: TOTAL: CompTIA Security+ Cert (SY0-701) | Udemy

Comprehensive and Detailed Explanation From Exact Extract:

Hashing is the process used to verify file integrity. When transferring a file between devices, a hash value (such as SHA-256) is generated before the transfer and then recomputed afterward. If the two hash values match, the file has not been altered, corrupted, or tampered with during transmission.

Authentication (A) verifies identity, not file integrity. Obfuscation (B) hides meaning but does not detect modification. Encryption (D) protects confidentiality but does not guarantee integrity unless combined with hashing or digital signatures.

CompTIA Security+ SY0-701 covers hashing under cryptographic functions used for integrity verification. Hash algorithms ensure that even a single byte change results in a completely different hash value (the avalanche effect). This makes hashing the standard method for verifying the integrity of transferred files, software downloads, backups, and system images.

Virtualization (D)allows multiple systems and services to be hosted onfewer physical machines, therebyreducing the total number of physical devicesand consequently thehardware attack surface. This also allows for better patching, monitoring, and control.

The fewer devices you manage physically, the fewer entry points there are for attackers to exploit hardware-level vulnerabilities.

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.

Tokenization is widely used in the financial industry to mask sensitive information such as credit card numbers, bank account details, or payment tokens. Tokenization replaces sensitive data with harmless surrogate values (tokens) that maintain format and usability but reveal nothing if intercepted.

Security+ SY0-701 highlights tokenization as a preferred method for PCI-DSS-regulated environments because:

It reduces exposure of actual sensitive data

It lowers compliance scope

Tokens can be mapped back to real data only through a secure token vault

It prevents attackers from accessing meaningful information

Hashing (B) is one-way and cannot be reversed, making it unsuitable for financial transactions that require retrieving original values. Salting (C) enhances password hashing security but does not mask data. Steganography (D) hides data inside images or media files, not used for structured data protection.

Thus, the correct answer is A: Tokenization.

A bastion host is a hardened system placed at a network boundary to absorb attacks and limit exposure. When deployed to mitigate risks from zero-day vulnerabilities, it acts as a compensating control. CompTIA Security+ SY0-701 defines compensating controls as alternative safeguards used when primary controls are insufficient or unavailable—such as when no patch exists for a zero-day.

Detective controls (B) identify issues but do not reduce exposure. Operational controls (C) refer to procedural or human-driven processes. Physical controls (D) secure physical environments (e.g., locks, cameras).

Because a bastion host compensates for the lack of a patch, the correct answer is A: Compensating.

Full disk encryption (FDE) is a technique that encrypts all the data on a hard drive, including the operating system, applications, and files. FDE protects the data from unauthorized access in case the laptop is lost, stolen, or disposed of without proper sanitization. FDE requires the user to enter a password, a PIN, a smart card, or a biometric factor to unlock the drive and boot the system. FDE can be implemented by using software solutions, such as BitLocker, FileVault, or VeraCrypt, or by using hardware solutions, such as self-encrypting drives (SEDs) or TrustedPlatform Modules (TPMs). FDE is a recommended encryption technique for laptops and other mobile devices that store sensitive data.

Partition encryption is a technique that encrypts only a specific partition or volume on a hard drive, leaving the rest of the drive unencrypted. Partition encryption is less secure than FDE, as it does not protect the entire drive and may leave traces of data on unencrypted areas. Partition encryption is also less convenient than FDE, as it requires the user to mount and unmount the encrypted partition manually.

Asymmetric encryption is a technique that uses a pair of keys, one public and one private, to encrypt and decrypt data. Asymmetric encryption is mainly used for securing communication, such as email, web, or VPN, rather than for encrypting data at rest. Asymmetric encryption is also slower and more computationally intensive than symmetric encryption, which is the type of encryption used by FDE and partition encryption.

Database encryption is a technique that encrypts data stored in a database, such as tables, columns, rows, or cells. Database encryption can be done at the application level, the database level, or the file system level. Database encryption is useful for protecting data from unauthorized access by database administrators, hackers, or malware, but it does not protect the data from physical theft or loss of the device that hosts the database.

References = Data Encryption – CompTIA Security+ SY0-401: 4.4, CompTIA Security+ Cheat Sheet and PDF | Zero To Mastery, CompTIA Security+ SY0-601 Certification Course - Cybr, Application Hardening – SY0-601 CompTIA Security+ : 3.2.

To enhance security for a system running an end-of-life operating system, placing the system in an isolated VLAN is the most effective approach. By isolating the system from the rest of the network, you can limit its exposure to potential threats while maintaining its functionality. This segmentation helps protect the rest of the network from any vulnerabilities in the outdated system.

Installing HIDS (Host-based Intrusion Detection System) can help detect intrusions but won't mitigate the risks posed by an unsupported OS.

Decommissioning may not be feasible if the system is critical.

Encrypting the system's hard drive protects data at rest but doesn't address vulnerabilities from an outdated OS​​​.

Detailed Explanation:This scenario highlights the need for training on the secure use of removable media. Users should learn to avoid using untrusted external storage devices to prevent malware infections. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Removable Media Controls and User Awareness Training"​​.

Detailed Explanation:Authorization refers to the process of granting or denying specific rights to a user after verifying their identity through authentication. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 1: General Security Concepts, Section: "Authentication, Authorization, and Accounting (AAA)"​​.

Active reconnaissance is a type of reconnaissance that involves sending packets or requests to a target and analyzing the responses. Active reconnaissance can reveal information such as open ports, services, operating systems, and vulnerabilities. However, active reconnaissance is also more likely to be detected by the target or its security devices, such as firewalls or intrusion detection systems. Port and service scans are examples of active reconnaissance techniques, as they involve probing the target for specific information. References = CompTIA Security+ Certification Exam Objectives, Domain 1.1: Given a scenario, conduct reconnaissance using appropriate techniques and tools. CompTIA Security+ Study Guide (SY0-701), Chapter 2: Reconnaissance and Intelligence Gathering, page 47. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 1.

A non-disclosure agreement (NDA) restricts employees from sharing proprietary or confidential information when they leave the company. Legal consequences may result from violating an NDA.

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"​​.

Poor input validation in databases typically leads to SQL Injection (SQLi) vulnerabilities, where attackers manipulate input fields to execute arbitrary SQL commands and gain unauthorized data access or control.

XSS (A) affects web applications' output rendering, command injection (B) affects OS commands, and buffer overflow (C) affects memory management, so they don't directly relate to database input validation.

SQLi is a critical vulnerability extensively covered in the Application Security domain【6:Chapter 6†CompTIA Security+ Study Guide】.

CVSS (Common Vulnerability Scoring System) provides a standardized way to rate the severity of software vulnerabilities. Organizations use CVSS scores to prioritize which vulnerabilities to address first, focusing on those with the highest risk.

Comprehensive and Detailed Explanation From Exact Extract:

A playbook is a step-by-step, just-in-time reference used by Security Operations Center (SOC) analysts when responding to security alerts, incidents, and suspicious activities. Playbooks provide documented procedures for common scenarios such as malware detection, phishing investigations, ransomware response, and account compromise.

According to the CompTIA Security+ SY0-701 exam framework, playbooks support incident response by reducing analyst guesswork and ensuring consistency. They include details such as triage steps, required tools, escalation paths, log sources, and containment actions. This makes playbooks the most suitable document for immediate reference during live investigations.

Change management policies (A) govern system or configuration changes, not SOC operations. Risk profiles (B) provide organizational risk overviews, not incident-response steps. SIEM profiles (D) define correlation rules or dashboards but are not procedural guides.

Therefore, the correct answer is playbooks, which enable efficient, standardized, and repeatable responses to operational security events.

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.

Classification is the process of assigning labels to files or data based on sensitivity, business value, or regulatory requirements. Proper classification guides handling, access controls, and protection measures.

Verification (A) and certification (B) are validation processes, and inventory (D) is a listing of assets.

Data classification is a foundational data governance control in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

A data retention policy is a set of rules that defines how long data should be stored and when it should be deleted or archived. An administrator assists the legal and compliance team with ensuring information about customer transactions is archived for the proper time period by following the data retention policy of the organization. This policy helps the organization to comply with legal and regulatory requirements, optimize storage space, and protect data privacy and security.

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​​.

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 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.

References = CompTIA Security+ SY0-701 study materials, focusing on system hardening and file permissions management​​.

Detailed Explanation:Access control lists (ACLs) allow administrators to fine-tune file permissions by specifying which users or groups have access to a file and defining the level of access. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Access Control Mechanisms"​​.

 Labeling all laptops with asset inventory stickers and associating them with employee IDs can provide several security benefits for a company. Two of these benefits are:

A. If a security incident occurs on the device, the correct employee can be notified. An asset inventory sticker is a label that contains a unique identifier for a laptop, such as a serial number, a barcode, or a QR code. By associating this identifier with an employee ID, the security team can easily track and locate the owner of the laptop in case of a security incident, such as a malware infection, a data breach, or a theft. This way, the security team can notify the correct employee about the incident, and provide them with the necessary instructions or actions to take,such as changing passwords, scanning for viruses, or reporting the loss. This can help to contain the incident, minimize the damage, and prevent further escalation.

F. Company data can be accounted for when the employee leaves the organization. When an employee leaves the organization, the company needs to ensure that all the company data and assets are returned or deleted from the employee’s laptop. By labeling the laptop with an asset inventory sticker and associating it with an employee ID, the company can easily identify and verify the laptop that belongs to the departing employee, and perform the appropriate data backup, wipe, or transfer procedures. This can help to protect the company data from unauthorized access, disclosure, or misuse by the former employee or any other party.

The other options are not correct because they are not related to the security benefits of labeling laptops with asset inventory stickers and associating them with employee IDs. B. The security team will be able to send user awareness training to the appropriate device. User awareness training is a type of security education that aims to improve the knowledge and behavior of users regarding security threats and best practices. The security team can send user awareness training to the appropriate device by using the email address, username, or IP address of the device, not the asset inventory sticker or the employee ID. C. Users can be mapped to their devices when configuring software MFA tokens. Software MFA tokens are a type of multi-factor authentication that uses a software application to generate a one-time password or a push notification for verifying the identity of a user. Users can be mapped to their devices when configuring software MFA tokens by using the device ID, phone number, or email address of the device, not the asset inventory sticker or the employee ID. D. User-based firewall policies can be correctly targeted to the appropriate laptops. User-based firewall policies are a type of firewall rules that apply to specific users or groups of users, regardless of the device or location they use to access the network. User-based firewall policies can be correctly targeted to the appropriate laptops by using the username, domain, or certificate of the user, not the asset inventory sticker or the employee ID. E. When conducting penetration testing, the security team will be able to target the desired laptops. Penetration testing is a type of security assessment that simulates a real-world attack on a network or system to identify and exploit vulnerabilities. When conducting penetration testing, the security team will be able to target the desired laptops by using the IP address, hostname, or MAC address of the laptop, not the asset inventory sticker or the employee ID. References = CompTIA Security+ Study Guide (SY0-701), Chapter 1: General Security Concepts, page 17. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 1.4: Asset Management, video: Asset Inventory (6:12).

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​​​.

An engineer should recommend the decommissioning of a network device when the device poses a security risk or a compliance violation to the enterprise environment. A device that cannot meet the encryption standards or receive authorized updates is vulnerable to attacks and breaches, and may expose sensitive data or compromise network integrity. Therefore, such a device should be removed from the network and replaced with a more secure and updated one.

Secure Shell (SSH) is a protocol used for secure command-line access to remote systems, while Secure File Transfer Protocol (SFTP) is an extension of SSH used specifically for securely transferring files. Both SSH and SFTP ensure that data is encrypted during transmission, protecting it from interception or tampering.

Web-based administration is a feature that allows users to configure and manage routers through a web browser interface. While this feature can provide convenience and ease of use, it can also pose a security risk, especially if the web interface is exposed to the internet or uses weak authentication or encryption methods. Web-based administration can be exploited by attackers to gain unauthorized access to the router’s settings, firmware, or data, or to launch attacks such as cross-site scripting (XSS) or cross-site request forgery (CSRF). Therefore, disabling web-based administration is a good practice to harden the routers within the corporate network. Console access, routing protocols, and VLANs are other features that can be configured on routers, but they are not the most appropriate to disable for hardening purposes. Console access is a physical connection to the router that requires direct access to the device, which can be secured by locking the router in a cabinet or using a strong password. Routing protocols are essential for routers to exchange routing information and maintain network connectivity, and they can be secured by using authentication or encryption mechanisms. VLANs are logical segments of a network that can enhance network performance and security by isolating traffic and devices, and they can be secured by using VLAN access control lists (VACLs) or private VLANs (PVLANs).

Installing a host-based content filtering solution on the endpoints ensures that web traffic is filtered locally even when the VPN connection to the on-premises proxy fails, maintaining protection for remote users.

Network access control (A) manages device network access, local gateway configuration (B) does not solve protection if VPN fails, and public NAT (C) exposes internal resources and increases risk.

Endpoint filtering complements VPN for resilient web security, covered in Security Architecture and Operations【6:Chapter 11†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.

Detailed Explanation:Rules of engagement specify the agreed-upon boundaries, scope, and procedures for a penetration test to ensure compliance and avoid disruption to the environment. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Penetration Testing Procedures"​​.

A Statement of Work (SOW) is a formal document detailing the scope, deliverables, timeline, and estimated hours for services such as penetration testing engagements.

BPA (Blanket Purchase Agreement) covers recurring purchases, SLA (Service Level Agreement) defines service quality expectations, and NDA (Non-Disclosure Agreement) protects confidentiality, none of which specify hours or detailed scope.

SOWs are fundamental in managing third-party risk and engagements, covered under Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】.

Access control lists (ACLs) are rules that specify which users or groups can access which resources on a file server. They can help restrict access to confidential data by granting or denying permissions based on the identity or role of the user. In this case, the administrator can use ACLs to quickly modify the access rights of the users and prevent them from accessing the data they are not authorized to see. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308 1

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.

The scenario describes a large number of unsolicited emails sent to multiple users. This is characteristic of phishing, which SY0-701 defines as mass-distributed fraudulent messages designed to trick recipients into clicking malicious links, downloading malware, or divulging sensitive information.

Phishing campaigns typically involve:

High volume

Non-targeted messaging

Use of spoofed addresses or fake content

Delivery through email systems

A watering-hole attack (A) compromises a legitimate website frequented by targets—not email. Typosquatting (B) relies on malicious websites with deceptive URLs. Business Email Compromise (C) involves highly targeted spear-phishing or impersonation attacks, not bulk email blasts.

Because this incident involves “hundreds of messages” delivered to “multiple users,” it clearly matches the characteristics of a phishing attack, not a sophisticated targeted attack type.

Phishing is the most common form of social engineering and is emphasized heavily in the Security+ exam due to its frequency and effectiveness.

Infrastructure as code (IaC) is a method of using code and automation to manage and provision cloud resources, such as servers, networks, storage, and applications. IaC allows for easy deployment, scalability, consistency, and repeatability of cloud environments. IaC is also a key component of DevSecOps, which integrates security into the development and operations processes. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 6: Cloud and Virtualization Concepts, page 294.

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"​​.

Data in transit is data that is moving from one location to another, such as over a network or through the air. Data in transit is vulnerable to interception, modification, or theft by malicious actors. A VPN (virtual private network) is a technology that protects data in transit by creating a secure tunnel between two endpoints and encrypting the data that passes through it2.

Exercising the right to be forgotten involves formally requesting the social media provider to delete all personal data associated with the account, ensuring removal from their servers and backups in accordance with privacy regulations.

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】.

Comprehensive and Detailed Explanation From Exact Extract:

Infrastructure as Code (IaC) is the technology required for automating infrastructure deployment. IaC allows organizations to define and deploy servers, networks, containers, and cloud resources using machine-readable configuration files rather than manual configuration. This leads to faster deployment, consistent environments, repeatability, version control, and lower human error.

CompTIA Security+ SY0-701 highlights IaC as a foundational component of DevOps and modern cloud operations. It supports automated provisioning through tools such as Terraform, Ansible, CloudFormation, and Puppet. IaC also enhances security by enabling automated compliance checks and standardized hardened configurations.

IaaS (B) is a cloud service model, not an automation mechanism. IoC (C) refers to Indicators of Compromise used in threat intelligence. IoT (D) refers to Internet-connected devices and is unrelated to infrastructure deployment.

Therefore, IaC is the required technology for automated, repeatable, secure infrastructure deployments.

Detailed Explanation:Avoidance involves choosing not to engage in activities or markets where certain risks are present. This is a proactive approach to risk management. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Risk Management Strategies"​​.

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.

Failure to comply with right-to-be-forgotten (data privacy) regulations can lead to significant fines imposed by regulatory authorities like GDPR enforcers. Such laws require companies to delete personal data upon user request.

Data breaches (B) are security incidents; revenue loss (C) and blackmail (D) may occur indirectly but fines are the direct legal consequence.

Regulatory compliance and consequences are critical topics in Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】

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

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】

 Root cause analysis is a process of identifying and resolving the underlying factors that led to an incident. By conducting root cause analysis as part of incident response, security professionals can learn from the incident and implement corrective actions to prevent future incidents of the same nature. For example, if the root cause of a data breach was a weak password policy, the security team can enforce a stronger password policy and educate users on the importance of password security. Root cause analysis can also help to improve security processes, policies, and procedures, and to enhance security awareness and culture within the organization. Root cause analysis is not meant to gather loCs (indicators of compromise) for the investigation, as this is a task performed during the identification and analysis phases of incident response. Root cause analysis is also not meant to discover which systems have been affected or to eradicate any trace of malware on the network, as these are tasks performed during the containment and eradicationphases of incident response. References = CompTIA Security+ SY0-701 Certification Study Guide, page 424-425; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 5.1 - Incident Response, 9:55 - 11:18.

VM escape allows an attacker to break out of a virtual machine to access the hypervisor or other adjacent virtual machines on the same host, effectively moving laterally to adjacent systems.

Side loading (B) involves loading malicious code in place of legitimate components. Remote code execution (C) allows running arbitrary code remotely. Resource exhaustion (D) causes denial of service by overusing resources.

VM escape is a known virtualization vulnerability detailed in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Comprehensive and Detailed Explanation From Exact Extract:

Non-repudiation ensures that a sender cannot deny sending a message. Digital signatures provide non-repudiation because they use the sender’s private key, which only the legitimate owner possesses. When the email recipient verifies the digital signature using the sender’s public key, it proves the email was sent by the true owner of the private key and has not been altered.

Confidentiality (B) ensures information is protected from unauthorized access and is usually achieved through encryption. Integrity (C) ensures data has not been modified, while authentication (D) verifies the identity of a user. Although digital signatures also support integrity and authentication, the specific property that prevents denial of sending the email is non-repudiation.

Security+ SY0-701 highlights digital signatures as a cryptographic mechanism used for authentication, integrity, and non-repudiation, especially in email security, PKI systems, and secure messaging.

Thus, the correct answer is Non-repudiation.

SIEM stands for Security Information and Event Management. It is a security alerting and monitoring tool that collects system, application, and network logs from multiple sources in a centralized system. SIEM can analyze the collected data, correlate events, generate alerts, and provide reports and dashboards. SIEM can also integrate with other security tools and support compliance requirements. SIEM helps organizations to detect and respond to cyber threats, improve security posture, and reduce operational costs. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Monitoring and Auditing, page 393. CompTIA Security+ Practice Tests: Exam SY0-701, 3rd Edition, Chapter 10: Monitoring and Auditing, page 397.

Placing a false (decoy) text file in a sensitive location (such as /docs/salaries) is an example of a honeytoken or deception technique. This technique is used to attract insider attackers and monitor their actions when they attempt to access the file.

Password spraying is a type of attack where an attacker tries a small number of commonly used passwords across a large number of accounts. The event logs showing failed login attempts for many user accounts from the same IP address are indicative of a password spraying attack, where the attacker is attempting to gain access by guessing common passwords.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of identity and access management and common attack vectors like password spraying​​.

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.

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​​.

The ability to automatically generate WAF (Web Application Firewall) policies during application deployment is a characteristic of Infrastructure as Code (IaC). IaC allows infrastructure components—such as firewalls, WAF policies, load balancers, and security groups—to be defined, version-controlled, and deployed programmatically.

According to Security+ SY0-701, IaC enhances DevSecOps workflows by embedding security controls directly into deployment pipelines, ensuring consistent, repeatable, and automated application protection. This reduces human error, eliminates configuration drift, and ensures that every new application instance is deployed with the correct WAF rules already in place.

IoT (B) involves connected devices.

IoC (C) refers to Indicators of Compromise.

IaaS (D) provides cloud infrastructure but does not itself automate security policy generation.

Thus, A: IaC is the correct concept enabling automated WAF policy creation.

Systems that control physical industrial processes—such as pumping gas, water control, electrical grids, or manufacturing lines—fall under SCADA (Supervisory Control and Data Acquisition) environments. SCADA systems are part of larger OT (Operational Technology) infrastructures and manage sensors, actuators, valves, flow controls, and telemetry.

CompTIA Security+ SY0-701 explains that SCADA environments typically:

Use legacy protocols (e.g., Modbus, DNP3)

Require high availability

Often run outdated operating systems

Have control systems that cannot easily be patched

Require specialized segmentation and monitoring

This exactly matches the scenario describing a “specialized legacy platform controlling gas flow inside pipes.”

IaaS (A) is cloud infrastructure and unrelated to industrial control. SDN (C) relates to software-defined networking, not physical industrial controls. IoT (D) includes smart devices but is not typically used for large-scale industrial gas control.

Thus, securing SCADA is the correct answer.

The misuse of personally identifiable information (PII) is often mitigated through employee training on privacy legislation and company compliance. Training on privacy legislation educates employees about legal requirements and consequences related to handling PII, such as GDPR or HIPAA. Company compliance training reinforces internal policies and procedures regarding data handling, acceptable use, and the repercussions of violations.

While social engineering and phishing training are important for security awareness, they address external threats rather than insider misuse of data. Risk management is a broader discipline focused on assessing and mitigating organizational risks but does not directly prevent employee misuse through training. Remote work training focuses on secure practices for working outside corporate environments, which is not the core issue here.

This approach aligns with Security Program Management and Oversight principles emphasizing compliance and privacy training to reduce insider threats【6:Chapter 16†CompTIA Security+ Study Guide】.

Changing the default password for the local administrator account on a VPN appliance is a basic security measure that would have most likely prevented the unexpected login to the remote management interface. Default passwords are often easy to guess or publicly available, and attackers can use them to gain unauthorized access to devices and systems. Changing the default password to a strong and unique one reduces the risk of brute-force attacks and credential theft. Using least privilege, assigning individual user IDs, and reviewing logs more frequently are also good security practices, but they are not as effective as changing the default password in preventing the unexpected login. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 116; Local Admin Accounts - Security Risks and Best Practices (Part 1)

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).

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​​.

Comprehensive and Detailed Explanation From Exact Extract:

Tokenization is the most effective method for protecting sensitive data at rest within a database. Tokenization replaces sensitive information—such as credit card numbers, SSNs, or personal identifiers—with meaningless surrogate values (tokens). The actual data is stored securely in a separate token vault, reducing exposure if the primary database is compromised.

Hashing (A) is one-way and protects integrity, not usability, making it inappropriate for data that must later be retrieved. Masking (B) hides data from users but does not secure stored data in the database. Obfuscation (D) makes data harder to understand but is reversible and not intended for strong security.

Security+ SY0-701 identifies tokenization as a key control for data-at-rest protection, especially in regulated industries like finance and healthcare. It prevents attackers from accessing real data even if the database is breached, significantly reducing risk and compliance impact. This aligns with the exam’s emphasis on confidentiality and data protection strategies in stored environments.

When the government bans a vendor, the primary concern for the company’s general counsel is sanctions, which are legal restrictions that prohibit the purchase, use, import, or continued operation of products associated with restricted entities. Security+ SY0-701 stresses that compliance with government regulations and legal mandates is a critical oversight responsibility. Failure to comply may result in severe penalties, including fines, loss of contracting eligibility, and reputational damage.

During a hardware refresh, general counsel will ensure the organization is not violating federal trade sanctions, procurement laws, or export/import restrictions. Even if devices are already purchased, continued use may still violate the sanctions, creating legal liability.

Data sovereignty (B) relates to storage location requirements, not vendor bans. Cost of replacement (C) is an operational and financial concern, not a legal one. Loss of license (D) typically applies to software but is not the primary legal concern tied to a government-issued vendor ban.

Therefore, sanctions are the general counsel’s primary focus.

Shadow IT refers to the use of information technology systems, devices, software, applications, and services without explicit IT department approval. This is the most likely cause of introducing vulnerabilities on a corporate network by deploying unapproved software, as such software may not have been vetted for security compliance, increasing the risk of vulnerabilities.

CompTIA Security+ SY0-701 Course Content: The concept of Shadow IT is discussed as a significant risk due to the introduction of unapproved and potentially vulnerable software into the corporate network​​.

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​​.

"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."

Detailed Explanation:COPE (Corporate-Owned, Personally Enabled) devices allow companies to manage and harden company-owned devices while still enabling limited personal use, reducing security risks while maintaining compatibility with corporate resources. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Mobile Device Deployment Models"​​.

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.

A legal hold (also known as a litigation hold) is a notification sent from an organization’s legal team to employees instructing them not to delete electronically stored information (ESI) or discard paper documents that may be relevant to a new or imminent legal case. A legal hold is intended to preserve evidence and prevent spoliation, which is the intentional or negligent destruction of evidence that could harm a party’s case. A legal hold can be triggered by various events, such as a lawsuit, a regulatory investigation, or a subpoena12

In this scenario, the company’s attorneys have requested that the security team initiate a legal hold in response to the lawsuit filed by the customers after the company was compromised. This means that the security team will most likely be required to retain any communications related to the security breach until further notice. This could include emails, instant messages, reports, logs, memos, or any other documents that could be relevant to the lawsuit. The security team should also inform the relevant custodians (the employees who have access to or control over the ESI) of their preservation obligations and monitor their compliance. The security team should also document the legal hold process and its scope, as well as take steps to protect the ESI from alteration, deletion, or loss34

Port 445 is used by the SMB protocol on Windows systems. Large volumes of unexpected traffic on TCP 445 are commonly associated with worms that exploit SMB vulnerabilities (such as WannaCry or NotPetya). Worms are self-replicating malware that spread rapidly across a network, consuming bandwidth, causing high latency, and often resulting in network outages. This matches the scenario given, where network unavailability and abnormal port 445 traffic are observed.

 The correct answer is A because multifactor authentication (MFA) is a method of verifying a user’s identity by requiring more than one factor, such as something the user knows (e.g., password), something the user has (e.g., token), or something the user is (e.g., biometric). MFA can prevent unauthorized access even if the user’s password is compromised, as the attacker would need to provide another factor to log in. The other options are incorrect because they do not address the root cause of the attack, which is weak authentication. Permissions assignment (B) is the process of granting or denying access to resources based on the user’s role or identity. Access management © is the process of controlling who can access what and under what conditions. Password complexity (D) is the requirement of using strong passwords that are hard to guess or crack, but it does not prevent an attacker from using a stolen password. References =You can learn more about multifactor authentication and other security concepts in the following resources:

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.

Detailed Explanation:

Time-of-day restrictions limit access to corporate systems based on predefined schedules. This ensures employees can only access resources during their assigned work hours. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Access Control Models"​​.

Risk threshold is the maximum amount of risk that an organization is willing to accept for a given activity or decision. It is also known as risk appetite or risk tolerance. Risk threshold helps an organization to prioritize and allocate resources for risk management. Risk indicator, risk level, and risk score are different ways of measuring or expressing the likelihood and impact of a risk, but they do not describe the maximum allowance of accepted risk. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 34; Accepting Risk: Definition, How It Works, and Alternatives

A statement of work (SOW) is a document that defines the scope, objectives, deliverables, timeline, and costs of a project or service. It typically includes an estimate of the number of hours required to complete the engagement, as well as the roles and responsibilities of the parties involved. A SOW is often used for penetration testing projects to ensure that both the client and the vendor have a clear and mutual understanding of what is expected and how the work will be performed. A business partnership agreement (BPA), a service level agreement (SLA), and a non-disclosure agreement (NDA) are different types of contracts that may be related to apenetration testing project, but they do not include an estimate of the number of hours required to complete the engagement. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 492; What to Look For in a Penetration Testing Statement of Work?

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"​​.

An Acceptable Use Policy (AUP) is an example of a managerial control. Managerial controls are policies and procedures that govern an organization's operations, ensuring security through directives and rules. The AUP defines acceptable behavior and usage of company resources, setting guidelines for employees.

Physical controls refer to security measures like locks, fences, or security guards.

Technical controls involve security mechanisms such as firewalls or encryption.

Operational controls are procedures for maintaining security, such as backup and recovery plans​​.

Federation is an access management concept that allows users to authenticate once and access multiple resources or services across different domains or organizations. Federation relies on a trusted third party that stores the user’s credentials and provides them to the requested resources or services without exposing them. Password complexity is a security measure that requires users to create passwords that meet certain criteria, such as length, character types, and uniqueness. Password complexity can help prevent brute-force attacks, password guessing, and credential stuffing by making passwords harder to crack or guess. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308-309 and 312-313 1

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.

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.

LDAP authentication on the printer (C)would require users toauthenticate before printing, enablingsecure print release. This ensures that documents arenot printed until the authorized user is physically present, which directly addresses the issue of missing confidential documents.

As perCompTIA Security+ SY0-701, Domain 3.1 (Access management), integratingauthentication mechanisms like LDAPimproves physical and document security in shared environments.

Cryptojacking is the likely cause in this scenario. It involves malware that hijacks the resources of infected computers to mine cryptocurrency, usually without the user's knowledge. This type of attack doesn't typically degrade performance significantly or result in obvious system failures, which matches the situation described, where the machines showed no signs of degraded performance or excessive failed logins.

Detailed Explanation:The activity described in the table, where multiple connection attempts are made on port 445 (used for SMB services), suggests a brute-force attack. The attacker likely used automated methods to guess credentials, causing multiple failures. Such attempts are ahallmark of brute-force attacks targeting shared resources. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Indicators of Malicious Activity"​​.

The scenario describes an instance where an employee receives a fraudulent invoice from a vendor that is not recognized in the company's vendor management system. This is a classic example of an invoice scam, where attackers attempt to trick organizations into making payments for fake or non-existent services. These scams often rely on social engineering tactics to bypass financial controls.

EDR (Endpoint Detection and Response) solutions monitor endpoint activities in real-time and can prevent malicious files from being downloaded or executed by detecting suspicious behaviors. In this case, EDR would block the download or alert the security team.

DLP (Data Loss Prevention) prevents unauthorized data exfiltration rather than blocking malware downloads. FIM (File Integrity Monitoring) tracks changes to files but doesn’t prevent downloads. NAC (Network Access Control) controls device access to the network but does not directly block file downloads.

EDR's proactive blocking capabilities are covered under the Security Operations domain in SY0-701【6:Chapter 11†CompTIA Security+ Study Guide】.

Comprehensive and Detailed Explanation From Exact Extract:

A fail-open configuration means that if the firewall experiences an outage or failure, traffic is allowed to pass through rather than being blocked. This design decision directly prioritizes availability over other security principles.

The CIA Triad (Confidentiality, Integrity, Availability) is central in SY0-701. A fail-open firewall risks allowing unauthorized or malicious traffic during a failure, sacrificing security controls in order to maintain service uptime. This is typically used in environments where interruptions are unacceptable, such as:

Public-facing websites

Critical customer applications

Healthcare systems

Financial transaction portals

Fail-closed configurations, in contrast, prioritize confidentiality and integrity by blocking traffic when a failure occurs.

Because the organization chose fail-open, it demonstrates that maintaining continuous access to the website is more important than preventing potential exposure. This approach is aligned with the Availability pillar of the CIA model.

The SY0-701 exam emphasizes this design choice under General Security Concepts, specifically in resilience, failover mechanisms, and risk-based decisions when selecting fail-open vs. fail-closed strategies.

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.

When conducting a forensic analysis after an incident, it's essential to prioritize the data collection process based on the "order of volatility." This principle dictates that more volatile data (e.g., data in memory, network connections) should be captured before less volatile data (e.g., disk drives, logs). The idea is to preserve the most transient and potentially valuable evidence first, as it is more likely to be lost or altered quickly.

To determine whether data exfiltration has occurred, the most effective tool is a packet capture (PCAP). Packet captures allow investigators to see exactly what data left the network, including file contents, payloads, headers, protocols, and destination information. PCAP files provide full-fidelity network evidence, enabling analysts to reconstruct sessions and review exfiltrated content byte-by-byte.

Security+ SY0-701 emphasizes PCAP as the gold standard for forensic network investigations, especially when dealing with:

Malware beaconing

Command-and-control (C2) traffic

Data leakage

Unauthorized transmissions

Network logs (C) provide summaries such as IP addresses, ports, and timestamps but do not show actual data contents. Metadata (B) gives descriptive information (e.g., file size, type) but not transmitted payloads. Application logs (A) show application-level events but do not capture network data.

If the analyst needs to confidently determine if sensitive information was exported to the attacker, only packet capture provides the required depth of visibility.

An unknown environment in penetration testing, also known as a black-box test, simulates an actual external attack where the tester has no prior knowledge of the system. This type of penetration test is designed to mimic real-world attack scenarios, where an attacker has little to no information about the target environment. The tester must rely on various reconnaissance and attack techniques to uncover vulnerabilities, much like a real-world attacker would. This approach helps organizations understand their security posture from an external perspective, providing insights into how their defenses would hold up against a true outsider threat.

Detailed Explanation:Host isolation ensures that a device is separated from the network, preventing it from accessing or being accessed by other network resources. This is typically achieved by quarantining the device. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Isolation and Containment"​​.

Dumpster diving is an attack method where attackers search through physical waste, such as discarded documents and printouts, to find sensitive information that has not been properly disposed of. In the context of printing centers, this could involve attackers retrieving printed documents containing confidential data that were improperly discarded without shredding or other secure disposal methods. This emphasizes the importance of proper disposal and physical security measures in cyber hygiene practices.
