when PAN is sent over the Internet, PAN must be encrypted with strong cryptography, which means it should use encryption techniques such as WEP, WPA, WPA2, or TLS/SSL to prevent unauthorized access or interception. This is one of the requirements for ensuring that PAN is protected from unauthorized access or interception.

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.

PCI DSS Requirement 3.6.4 states that entities must retire or replace keys when the keys have reached the end of their cryptoperiod, which is the time span during which a specific key can be used for cryptographic operations1. The retired key must not be used for encryption operations, as it may have been compromised or weakened by cryptanalysis, and may not provide adequate protection for the data. The retired key may still be used for decryption operations, if needed, to access historical data that was encrypted under the retired key2. Therefore, the correct answer is option A.

The other options are not true regarding the cryptographic key retirement and replacement. Option B is not true because PCI DSS does not specify a retention period for the cryptographic key components from the retired key, although it requires entities to securely delete cryptographic material when it is no longer needed for business or legal reasons1. Option C is not true because PCI DSS does not require a new key custodian tobe assigned, although it requires entities to define and document the roles, responsibilities, and accountability of all key custodians1. Option D is not true because PCI DSS does not require all data encrypted under the retired key to be securely destroyed, although it requires entities to render cardholder data unreadable when it is no longer needed for business or legal reasons1. References:

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:

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.
