As specified underRequirement 11.5.2.1, comparisons of critical files (e.g., config files, executables) using change-detection mechanisms (e.g., FIM tools)must occur at least weekly. This ensures timely detection of unauthorized changes or tampering.

Option A:✅Correct. Weekly is theminimum frequencyrequired.

Option B:❌Incorrect. A defined "period" is not sufficient unless it's weekly or more frequent.

Option C:❌Incorrect. Scans should not wait for changes; they should detectunexpectedones.

Option D:❌Incorrect. Monthly is too infrequent for PCI DSS compliance.

 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​​.

According toRequirement 9.3.1and9.4.1.2, physical access control mechanisms — including badge readers — must beprotected against tampering or disablingto prevent unauthorized access and maintain the integrity of access logs.

Option A:Correct. Physical access control systems must be protected from tampering.

Option B:Incorrect. Video cameras are requiredonly where appropriate; badge access may suffice.

Option C:Incorrect. Access logs must beretained for at least three months, not deleted monthly (see 9.4.1.3).

Option D:Incorrect. Motion sensors are not specifically required.
