PCI QSA_New_V4 Exam Dumps

Customized Approach Overview

Appendix E of PCI DSS v4.0 outlines the customized approach, which allows entities to demonstrate their control effectiveness using methods that differ from the defined approach.

Assessor Responsibilities

QSAs must document and maintain detailed evidence for each customized control implemented by the entity.

Evidence must support how the customized control meets the security objectives of the original requirement.

Testing and Validation

The QSA must perform validation to confirm the customized control's adequacy and effectiveness and ensure it sufficiently addresses the requirement's intent.

Documentation

All findings, testing procedures, and conclusions must be recorded in the Report on Compliance (ROC) Appendix E, providing traceability and transparency.

Attestation of Compliance (AOC):

The AOC is a document that confirms an entity's compliance with PCI DSS requirements. It is signed by the entity (merchant or service provider) and the Qualified Security Assessor (QSA) if a QSA is involved.

Different AOC Templates:

PCI DSS provides distinct templates for service providers and merchants, tailored to their respective roles and responsibilities within the cardholder data environment (CDE).

Invalid Options:

B: PCI SSC does not sign AOCs; they are signed by the merchant/service provider and the QSA.

C: AOCs differ between ROCs and SAQs, so the same template is not universally used.

D: Both the merchant/service provider and the QSA/ISA (Internal Security Assessor) must sign the AOC when applicable.

Software Security Framework Overview

PCI SSC's Software Security Framework (SSF) encompasses Secure Software Standard and Secure Software Lifecycle (Secure SLC) Standard.

Software developed under the Secure SLC Standard adheres to security-by-design principles and can leverage the SSF during PCI DSS assessments.

Applicability

The framework is primarily for software developed by entities or third parties adhering to PCI SSC standards.

It does not apply to legacy payment software listed under PA-DSS unless migrated to SSF.

Incorrect Options

Option A: Not all payment software qualifies; it must align with SSF requirements.

Option B: PCI PTS devices are subject to different security requirements.

Option C: PA-DSS-listed software does not automatically meet SSF standards without reassessment.

Audit Log Access Control:

PCI DSS Requirement 10.7 restricts access to audit logs to individuals with a job-related need to protect the integrity and confidentiality of the logs.

Rationale for Job-Related Need:

Limiting access reduces the risk of tampering, accidental modification, or exposure of sensitive information.

Invalid Options:

A: Individuals who performed the activity should not necessarily view logs unless required.

B/C: Read/write access or administrator privileges are not prerequisites for log viewing.

Hashing and Truncation

PCI DSS Requirement 3.4 mandates protecting stored PAN using methods like hashing and truncation. If both versions coexist, controls must ensure they cannot be combined to reconstruct the original PAN.

Incorrect Options

Option B: Truncation is unrelated to hashed PANs.

Option C: Correlation of hashed and truncated versions to identify the PAN violates PCI DSS principles.

Option D: Coexistence of hashed and truncated PANs is permissible if proper controls are in place.
