all network transmissions must be logged by an entity’s security information and event management (SIEM) system or equivalent tool, which means they should record all network events and activities related to cardholder data processing and transmission. This is one of the requirements for ensuring that network transmissions are monitored and audited.

According to requirement 1, network security controls are intended to control network traffic between two or more logical or physical network segments, which means they should prevent unauthorized access, modification, or disclosure of cardholder data or transactions over the network. This is one of the requirements for ensuring that network security controls are implemented and maintained in accordance with PCI DSS.

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:

According to the PCI DSS v3.2.1 Quick Reference Guide1, settlement occurs when a merchant receives payment from a card issuer for a completed transaction and delivers goods or services to a customer or another party as agreed upon in advance by both parties, subject to any conditions imposed by either party upon delivery or payment, including but not limited to acceptance, rejection, return, exchange, refund, cancellation, modification, suspension, termination or revocation by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment;

According to the PCI DSS v3.2.1 Quick Reference Guide1, installing one primary function per server is intended to prevent server functions with a lower security level from introducingsecurity weaknesses to higher-security functions on the same server. This is one of the requirements for ensuring that server functions are isolated from each other.

According to the PCI DSS v3.2.1 Quick Reference Guide1, pre-production environments that are located within the cardholder data environment can be used for testing, as long as they are not accessible from untrusted networks and are monitored for any changes or vulnerabilities. This is one of the requirements for ensuring that testing environments are isolated from production environments.

The PCI DSS requires that access to databases containing cardholder data is restricted to authorized users and applications, and that direct access to such databases is prohibited. According to the PCI DSS Requirement 7.1.2, “Restrict access to privileged user IDs to least privileges necessary to perform job responsibilities.” Furthermore, according to the PCI DSS Requirement 8.3.1, “Implement multi-factor authentication for all non-console access into the cardholder data environment for personnel with administrative access.” Therefore, the scenario that meets the PCI DSS requirements for restricting access to databases containing cardholder data is the one where user access to the database is only through programmatic methods, such as through an application interface that enforces authentication, authorization, and encryption. The other scenarios either allow direct access to the database, or do not limit the access to the least privileges necessary, or do not use multi-factor authentication for administrative access. References: [PCI DSS v3.2.1], Card Production Security Assessor - Logical - Credly

PCI DSS Requirement 10.5.5 states that entities must restrict access to audit logs to those with a job-related need1. This is to prevent unauthorized or malicious users from tampering with or deleting the audit logs, which could compromise the integrity andavailability of the logs and hinder the detection and investigation of security incidents. Audit logs contain sensitive and confidential information, such as cardholder data, user identities, system activities, and security events, and therefore must be protected from unauthorized viewing, modification, or deletion2. Individuals with a job-related need are those who have a legitimate and documented business reason to access the audit logs, such as system administrators, security personnel, auditors, or investigators3. Therefore, the correct answer is option D.

The other options are not true regarding the access control for audit log files. Option A is not true because individuals who performed the logged activity may not have a job-related need to view the audit logs, and may have a conflict of interest or malicious intent to alter or erase the logs. Option B is not true because individuals with read/write access may not have a job-related need to access the audit logs, and may pose a risk of unauthorized or accidental modification or deletion of the logs. Option C is not true because individuals with administrator privileges may not have a job-related need to access the audit logs, and may abuse their privileges or be targeted by attackers to compromise the logs. References:
