QSA_New_V4 Exam Dumps : Qualified Security Assessor V4 Exam

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.

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.

 Testing with Live PANs

PCI DSS Requirement 6.4.3 requires that live PANs (Primary Account Numbers) only be used in secure and controlled environments within the CDE.

Pre-production environments located within the CDE must adhere to all PCI DSS requirements for security and monitoring​​.

 Prohibited Uses

Testing with live PANs in environments outside the CDE violates PCI DSS. Only simulated data should be used in less secure testing environments.

 Incorrect Options

Option A: Production environments are for real transactions, not testing.

Option B: Test environments outside the CDE are insecure for live PANs.

Option D: The QSA environment is irrelevant to the organization’s CDE testing controls.
