PCI SSC QSA_New_V4 Dumps

 Stateful Inspection

PCI DSS Requirement 1.2 specifies the need for stateful inspection to track the state of active connections. This ensures that only valid responses to communication initiated by trusted networks are allowed.

Invalid or unsolicited response traffic is blocked to prevent exploitation of vulnerabilities​​.

 Key Functionality of Stateful Firewalls

Stateful firewalls maintain session information and only allow traffic that matches an existing session or expected response.

 Incorrect Options

Option A: Administrative access restrictions are important but unrelated to stateful responses.

Option C: Baseline configurations are a different security control.

Option D: Logging and correlation are for threat detection, not stateful response.

According toRequirement 2.2.6,default passwords must be changed before systems are installed on the network. The use of default credentials (such as "admin/admin") presents a major security risk and is a well-known vector for breaches.

Option A:❌Incorrect. Changing within 30 days is not soon enough per PCI DSS.

Option B:❌Incorrect. Resetting to default would defeat the purpose of secure configuration.

Option C:✅Correct. The requirement is to change default passwordsprior to network connection.

Option D:❌Incorrect. Password expiration policies are a separate topic under Requirement 8.

PerRequirement 10.6.1, PCI DSS mandates that time-synchronization technology be used, andsystems must be synchronized to a central time serverthat itself receives time from an approved external source. This ensures logs can be accurately correlated.

Option A:Incorrect. Time inconsistency arises if each system operates independently.

Option B:Incorrect. Time configuration must berestricted to authorised personnel only.

Option C:Correct. Time should be sourced from a centralised server which is in sync with reliable external sources.

Option D:Incorrect. Each system peering independently can cause inconsistencies.

 Requirement Context:

PCI DSS Requirement 12.5 mandates that security policies and operational procedures are not only documented but also distributed to relevant parties to ensure clarity and compliance.

 Importance of Distribution and Awareness:

All affected parties, including employees, contractors, and third parties with access to the cardholder data environment (CDE), must receive and understand the policies. This ensures they adhere to the security measures​​.

 Review and Updates:

Security policies must be kept up to date and reviewed at least annually or after significant changes in the environment. While other options such as encryption or restricted access are important for security, the critical focus is on distribution and awareness to ensure operational effectiveness​​.

 Testing and Validation:

During assessments, QSAs validate the implementation by examining training records, communication logs, and acknowledgment forms signed by affected parties​​.

 Relevant PCI DSS v4.0 Guidance:

Section 12.5.1 of PCI DSS v4.0 outlines that the dissemination of policies must ensure that all personnel understand their roles in securing the environment​​.

 Key Management Requirements:

PCI DSS Requirement 3.5 specifies the protection of cryptographic keys, including encryption, storage in secure cryptographic devices (SCDs), or as key components to ensure security and prevent unauthorized access​​.

 Clarifications on Cryptographic Key Protection:

A/B:Public keys and key strength requirements are not specified in this context.

D:Separation of duties mandates that key-encrypting and data-encrypting keys must not be assigned to the same custodian.

 Testing and Validation:

QSAs verify compliance by examining key management practices, storage mechanisms, and access controls for cryptographic keys during the assessment​.

According toRequirement 12.10.1, an effectiveincident response plan (IRP)must include steps to detect, respond to, and contain incidents such asunauthorised wireless access points. PCI DSS11.2.1also mandates quarterly rogue AP detection.

Option A:❌Incorrect. Notification to PCI SSC is not required; notification goes toacquirers/payment brands.

Option B:✅Correct. The IRP must includeresponse to unauthorised wireless access detection.

Option C:❌Incorrect. Records must beretained, not deleted.

Option D:❌Incorrect. Retaliatory or offensive actions arenot allowed or recommended.

Requirement 4.2.1.1states that PAN must beprotected with strong cryptographywhenever transmitted overopen or public networks, includingprivate wirelesswhere security is not assured. While not allprivate wired networksrequire encryption,wirelessis generally considered untrusted.

Option A:✅Correct. PAN must be encrypted overprivate wireless networksdue to potential interception risks.

Option B:❌Incorrect. Privatewirednetworks typically don’t require encryption unless they’re untrusted.

Option C & D:❌Incorrect. PANalways requires protectionover public networks.

Requirement 9.6.1mandates theclassification of mediaso that appropriatehandling, storage, and disposalprocedures are applied based on thesensitivity of the data. This ensures that media storing cardholder data is not treated the same as media containing non-sensitive content.

Option A:✅Correct. Classifying media enablesrisk-appropriate protections.

Option B:❌Incorrect. Movement schedules are not mandated.

Option C:❌Incorrect. Labeling is a recommended control but not the primary intent.

Option D:❌Incorrect. Destruction must bebased on data classification, not uniform timing.

PCI DSSRequirement 8.4.2requiresmulti-factor authentication (MFA)to consist of two or moreindependent authentication factors. MFA must alsonot involve shared credentials, so each certificate must be tied to a specific individual.

Option A:❌Incorrect. MFA must apply toall applicable users, not just admins.

Option B:✅Correct. This meets PCI DSS: unique credentials per user and non-shared certificates.

Option C:❌Incorrect. Retaining certificates post-employment is a risk, not a compliance action.

Option D:❌Incorrect. PCI DSS doesn’t mandate 90-day certificate rotation; rather, secure usage and revocation are key.

Scope definition in PCI DSS v4.0.1 (Section 4)includesany system that can impact the security of the CDE. Time synchronization servers such asNTParecritical to log integrity(Requirement 10.6), and if they provide services to CDE systems,they are in scopeeven if they do not directly process cardholder data.

Option A:❌Incorrect. Scope is broader than just databases.

Option B:❌Incorrect. Time serversimpact log security, so they are in scope.

Option C:❌Incorrect. PCI DSS scope includes systems thataffect the securityof CDE, not just those storing card data.

Option D:✅Correct. Internal NTP servers providing services to the CDE arein scope.

PerSection 11 and 12of PCI DSS v4.0.1, assessors arerequired to use the official PCI SSC ROC Reporting Template. This ensures uniformity and completeness across all assessments. The same requirement applies to bothmerchants and service providersundergoing afull assessment (ROC).

Option A:✅Correct. PCI SSC mandates use of its official ROC template.

Option B:❌Incorrect. Custom assessor templates arenot permitted.

Option C:❌Incorrect. Assessorsmust notcreate their own templates.

Option D:❌Incorrect. The ROC template is used forbothmerchants and service providers, where applicable.

Under theCustomized Approach, assessors are responsible forderiving and documenting the testing proceduresinAppendix E of the Report on Compliance (ROC). The assessor must ensure the controlmeets the requirement objectiveand validate it throughcustom testing.

Option A:❌Incorrect. Ongoing monitoring is the entity’s responsibility, not the assessor’s.

Option B:✅Correct. The assessor must derive anddocument testingin Appendix E.

Option C:❌Incorrect. The entity documents control details; the assessor documents test results.

Option D:❌Incorrect. Theentitymust perform the targeted risk analysis, not the assessor.

According toRequirement 3.5.1.2, whendisk-level encryptionis used (e.g., full disk encryption), access control must beseparate from the operating systemto prevent unauthorised users from bypassing controls by booting the system.

Option A:✅Correct. Disk encryption must useindependent authentication mechanisms.

Option B:❌Incorrect. Sharing authentication with the OSviolates independence.

Option C:❌Incorrect. Association with local accounts may not ensure separate access control.

Option D:❌Incorrect. Key storage within user accounts is not secure or compliant.

 PCI DSS Reporting Expectations:

When documenting that a requirement is "In Place," the ROC must clearly describe how compliance was validated by the assessor. This involves detailing the evidence observed, such as system configurations, documentation, and personnel interviews​.

 ROC Documentation Guidelines:

The ROC Reporting Template specifies that each "In Place" response must include evidence demonstrating compliance with the requirement, such as testing observations and validation of implemented controls​.

 Eliminating Incorrect Options:

A:Project plans are not sufficient to demonstrate current compliance.

C/D:Responses discussing non-implementation or non-compliance are irrelevant when the requirement is "In Place."

 PCI DSS v4.0 ROC Template Guidance:

Appendix sections in the ROC provide specific instructions for assessors to document the testing performed, evidence reviewed, and results​.

Requirement 6.4.3.1clarifies that if live PANs are to be used in testing, the test environment mustmeet all applicable PCI DSS controls. Thus,testing with live PAN is only allowed if the test environment is within the CDEand fully secured.

Option A:❌Incorrect. Testing should not happen in production.

Option B:❌Incorrect. It must be within the CDE if live PAN is involved.

Option C:✅Correct. Live PANs can be used inpre-production environments within the CDE.

Option D:❌Incorrect. There’s no requirement to test only within QSA environments.

UnderAppendix D – Customized Approach, it is clearly stated that theentity is responsiblefor completing theControls Matrixand theTargeted Risk Analysis (TRA). The assessor may assist in completion, but accountability for content lies with the entity.

Option A:Incorrect. QSAs may assist but are not solely responsible.

Option B:Incorrect. This overstates who is responsible; only the entity is ultimately accountable.

Option C:Correct. The entity being assessed is responsible for completing the Controls Matrix and TRA.

Option D:Incorrect. Card brands or acquirers are not involved in document creation.

Requirement 11.5.1mandates that organisations deployintrusion-detection or prevention toolstomonitor traffic and generate alertsfor suspicious activity. The goal is tonotify personnel quicklyof a possible breach.

Option A:❌Incorrect. IDS/IPS isnot requiredon every component — only where it adds value.

Option B:✅Correct. IDS/IPS must be configured toalert on potential compromises.

Option C:❌Incorrect. Segmentation is a separate concern under Requirement 1.

Option D:❌Incorrect. IDS is not for discovering cardholder data.

Requirement 5.2.1.1clarifies thatanti-malware solutions are requiredonall in-scope systems,unlessthe system is evaluated asnot at risk for malware(e.g., Linux-based appliances with no Internet access). These risk evaluations must be documented and justified (5.2.3.1).

Option A:❌Incorrect. PCI DSS allows exceptions for systems not at risk.

Option B:❌Incorrect. Anti-malware applies to systems, not portable media per se.

Option C:❌Incorrect. Anti-malware scope is broader than just PAN-storing systems.

Option D:✅Correct. Systems not at risk can be excluded if justified and documented.

 Visitor Management Requirements:

PCI DSS Requirement 9.3 specifies that visitors must be escorted at all times in areas where cardholder data is present to prevent unauthorized access or breaches​​.

 Invalid Options:

B:Visitor badges must be distinguishable from employee badges.

C:Visitor logs are necessary but do not need detailed personal information like addresses.

D:Retaining visitor identification for 30 days is not a requirement.

 PAN Transmission Protection

PCI DSS Requirement 4.1 mandates strong cryptography for PAN during transmission over both public and private wireless networks to prevent unauthorized interception​​.

 Incorrect Options

Options B and D: PAN protection is not required for private wired networks.

Option C: PAN must be protected during transmission over public wireless networks.

 Scope of Anti-Malware Requirements

PCI DSS Requirement 5 mandates the use of anti-malware solutions on all in-scope systems unless the system is specifically documented as not being at risk from malware.

Examples of systems not at risk include those using operating systems that do not support anti-malware tools, provided proper justifications and alternative controls are implemented​​.

 Assessment Considerations

QSAs must verify and document why a system is considered "not at risk."

Systems storing, processing, or transmitting cardholder data or that could impact the CDE are generally in-scope for anti-malware​​.

 Incorrect Options

Option A: While CDE systems and connected systems require protection, the requirement applies specifically to systems at risk from malware.

Option B: Portable electronic storage is not explicitly called out for universal anti-malware but must be controlled in line with overall security policies.

Option C: Systems storing PAN are only a subset of in-scope systems.

 Purpose of Classifying Media

PCI DSS v4.0 emphasizes the need to classify media based on the sensitivity of the data it contains. Media classification ensures appropriate handling, storage, and destruction processes​​.

 Media Protection Requirements

Media containing cardholder data must be securely stored, transferred, and destroyed when no longer needed.

Classification informs the level of protection required, such as encryption, physical security, or controlled access​​.

 Incorrect Options

Option B: Moving media quarterly is not a requirement.

Option C: Labeling as "Confidential" is insufficient without a comprehensive protection strategy.

Option D: Destruction schedules should depend on retention requirements and data sensitivity, not a universal timeline.
