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.

Segmentation is a method of isolating system components that store, process, or transmit cardholder data from systems that do not, by using security controls such as firewalls, routers, switches, or other devices1. Segmentation can reduce the scope of the cardholder data environment (CDE) and thus reduce the scope of the PCI DSS assessment, as only the systems and networks within the CDE or connected to the CDE are subject to PCI DSS requirements2. However, segmentation is not mandatory for PCI DSS compliance, and it is the responsibility of the entity to define and document the scope of their CDE and the segmentation controls they use2.

The assessor’s role is to verify the scope of the CDE and the effectiveness of the segmentation controls, as specified in PCI DSS Requirement 11.3.43. The assessor must verify that the segmentation controls are configured properly and functioning as intended, and that they allow only necessary traffic into the CDE. The assessor must also perform penetration testing on the segmentation controls at least annually and after anychanges to the segmentation methods, to confirm that there are no exploitable vulnerabilities that could allow an attacker to access the CDE from out-of-scope systems3. Therefore, the correct answer is option D.

The other options are not true regarding the role of the assessor in verifying segmentation for PCI DSS. Option A is not true because the assessor must verify not only that the segmentation controls allow only necessary traffic into the CDE, but also that they are configured properly and functioning as intended, as stated in option D. Option B is not true because the assessor does not need to verify that the payment card brands have approved the segmentation, as PCI DSS does not require such approval, although the payment card brands may have their own policies and procedures for segmentation that the entity must follow2. Option C is not true because the assessor does not need to verify that approved devices and applications are used for the segmentation controls, as PCI DSS does not mandate the use of specific devices or applications for segmentation, although it requires the entity to use industry-accepted and strong methods for segmentation2. References:

Guidance for PCI DSS Scoping and Network Segmentation

PCI DSS v3.2.1

According to requirement 4, PAN must be protected with strong cryptography for transmission over private wireless networks, which means it should use encryption techniques such as WEP, WPA, WPA2, or TLS/SSL to prevent unauthorized access or interception of cardholder data over wireless networks. This is one of the requirements for ensuring that PAN is protected from unauthorized access or interception.

According to the PCI DSS v3.2.1 Quick Reference Guide1, a compensating control must address the risk associated with not adhering to a PCI DSS requirement and must be approved by an authorized person before implementation. This is one of the requirements for reducing or eliminating a risk that cannot be eliminated by other means

According to the PCI DSS v3.2.1 Quick Reference Guide1, audit logs must be retained for at least 1 year, with the most recent 3 months immediately available. This is one of the requirements for ensuring that audit logs are available for review and analysis.

According to the PCI DSS v3.2.1 Quick Reference Guide1, screening and background checks for personnel with access to the cardholder data environment are required, as they may pose a risk if they have compromised or stolen cardholder data in the past or present. This is one of the requirements for ensuring that personnel with access to cardholder data are qualified and trustworthy.

According to requirement 3.1.2, multi-tenant service providers must ensure that customers cannot access another entity’s cardholder data environment, which means they should isolate each customer’s cardholder data from other customers’ cardholder data and prevent unauthorized access or disclosure. This is one of the requirements for ensuring that multi-tenant service providers protect each customer’s cardholder data.

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:

classifying media that contains cardholder data is intended to ensure that media is property protected according to the sensitivity of the data it contains, which means it should be markedwith labels or tags that indicate its level of confidentiality or integrity. This is one of the requirements for ensuring that media containing cardholder data is properly labeled.

According to the PCI DSS v3.2.1 Quick Reference Guide1, system configuration and parameter files must be monitored by a change-detection mechanism (for example, a file-integrity monitoring tool). This is one of the requirements for ensuring that changes to system configuration and parameter files are detected and verified.
