PCI SSC Assessor_New_V4 Exam With Confidence Using Practice Dumps

According to requirement 3.1.2, an assessment with at least one requirement marked as Not Tested is considered a partial assessment, which means it does not meet all the requirements and controls defined in Appendix E of the PCI DSS v3.2.1 Quick Reference Guide1. This is one of the requirements for ensuring that assessments are conducted in accordance with PCI DSS.

According to the PCI DSS v3.2.1 Quick Reference Guide1, active network connections are tracked so that invalid response traffic can be identified. This is one of the requirements for preventing replay attacks and ensuring secure communication.

PCI DSS Requirement 11.5 states that entities must deploy a change-detection mechanism (for example, file-integrity monitoring tools) to alert personnel to unauthorized modification of critical system files, configuration files, or content files; and configure the software to perform critical file comparisons at least weekly1. This is to ensure that any unauthorized or malicious changes to the files are detected and reported in a timely manner, and that the integrity and security of the files are maintained. Critical files are those that affect the security of the cardholder data environment (CDE), such as system files, application executables, configuration files, database files, and log files2. Therefore, the correct answer is option A.

The other options are not true regarding the frequency of critical file comparisons for a change-detection mechanism. Option B is not true because PCI DSS does not allow the entity to define the periodicity of the file comparisons, as it specifies a minimum frequency of at least weekly1. Option C is not true because PCI DSS does not limit the file comparisons to only after a valid change is installed, as it requires the file comparisons to be performed at least weekly regardless of the change status1. Option D is not true because PCI DSS does not allow the file comparisons to be performed at least monthly, as it requires a higher frequency of at least weekly1. References:
