QSA_New_V4 Exam Dumps : Qualified Security Assessor V4 Exam

Customized Approach Overview:

Under PCI DSS v4.0, entities can use a Customized Approach to meet requirements by implementing controls tailored to their environment. This allows flexibility while still achieving the intent of the security requirement.

Role of Assessors:

Assessors (QSAs) are responsible for evaluating both the implementation of customized controls and ensuring these controls fulfill the security objectives of the PCI DSS requirements​​.

QSAs must document the evaluation, evidence reviewed, and results in the Report on Compliance (ROC).

Controls Matrix and Targeted Risk Analysis (TRA):

The Controls Matrix and TRA are key components of the Customized Approach. QSAs assist in verifying the accuracy and completeness of these tools during assessments​​.

Documenting in the ROC:

The ROC must include a narrative explaining the assessor’s findings regarding the customized control, validation methods, and any evidence collected​.

Relevant PCI DSS v4.0 Guidance:

Appendix D and E of the PCI DSS v4.0 ROC Template emphasize that QSAs can evaluate and confirm adherence to the Customized Approach provided this is documented comprehensively in the ROC​.

Intent of Risk Ranking

PCI DSS Requirement 6.3.2 requires that entities assign a risk ranking to vulnerabilities to prioritize remediation efforts.

This ensures that the most critical vulnerabilities are addressed in a timely manner, reducing the risk to the CDE​​.

Practical Implementation

Vulnerabilities are assessed based on potential impact and likelihood of exploitation, typically using industry-standard frameworks like CVSS.

High-risk vulnerabilities may require immediate attention, while lower-priority issues are remediated per schedule.

Incorrect Options

Option A: PCI DSS does not mandate a 30-day remediation window for all vulnerabilities; remediation timelines depend on risk.

Option B: Quarterly ASV scans are still required even with risk ranking.

Option D: Installing patches quarterly does not align with the dynamic prioritization of risks.

Physical Security Requirements:

PCI DSS Requirement 9.1.1 mandates that physical access control systems (like badge readers) must be protected against tampering or disabling to ensure continuous security​​.

Current Implementation:

The merchant’s badge access-control system provides essential logging of access events but must also be protected against tampering to comply with PCI DSS.

Invalid Options:

B:Video cameras are recommended but not explicitly required if access controls effectively ensure security.

C:Secure deletion of access-control logs is not a PCI DSS requirement; logs must be retained as per retention policies.

D:Motion-sensing alarms are not mandatory under PCI DSS physical security requirements.
