PCI SSC QSA_New_V4 Exam With Confidence Using Practice Dumps

Requirement 10.5.1.1requires thataudit logs be protected from unauthorised viewing and modification, and access should berestricted to individuals with a job-related need to view them. This principle aligns with least privilege and ensures accountability.

Option A:❌Incorrect. The person who performed the action may not need to view logs.

Option B:❌Incorrect. Read/write access istoo permissive.

Option C:❌Incorrect. Not all administrators need access to logs.

Option D:✅Correct. Access should bebased on job function.

 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.

 Requirement for Secure Transmission:

PCI DSS Requirement 4.1 mandates that cardholder data sent over open public networks must be protected with strong cryptographic protocols. Accepting only trusted keys ensures data integrity and prevents unauthorized access​​.

 Key Validation Practices:

Trusted keys and certificates are verified to ensure authenticity. Using untrusted keys compromises the security of the encrypted communication.

 Prohibited Practices:

A/D:Configuring protocols to accept all certificates or lower encryption strength violates PCI DSS encryption guidelines.

B:Proprietary protocols are not inherently compliant unless they meet strong cryptographic standards.

 Testing and Verification:

Assessors verify the implementation of trusted keys by examining encryption settings, reviewing certificate chains, and conducting tests to confirm only trusted connections are accepted​​.
