Key Management Requirements:

PCI DSS Requirement 3.6.5 specifies that when a cryptographic key is retired, it must no longer be used for encryption operations but may still be retained for decryption purposes as needed (e.g., to decrypt historical data until it is re-encrypted with the new key)​.

Secure Key Retirement:

Retired keys should be securely stored or destroyed based on the organization’s key management policy to prevent unauthorized access or misuse.

Reference in PCI DSS Documentation:

Section 3.6.5 emphasizes that retired keys must be rendered inactive for further encryption while allowing use for decryption, ensuring data continuity and compliance​.

Relevant PCI DSS Requirement: Internal vulnerability scans are discussed under PCI DSS Requirement 11.3.1, which requires organizations to perform internal vulnerability scanning as part of their regular vulnerability management process.

Frequency and Trigger for Internal Scans:

PCI DSS v4.0 explicitly states that internal vulnerability scans should be conducted at least quarterly and after any significant change.

A "significant change" can include modifications such as infrastructure upgrades, addition of new systems or software, and configuration changes that may impact security.

Approved Scanning Vendor (ASV):

Internal scans do not require an Approved Scanning Vendor (ASV). ASVs are specifically used for external vulnerability scans.

Qualified Security Assessor (QSA) Involvement:

QSAs are not mandated to perform internal scans. Organizations can use internal teams or trusted third-party resources for this purpose, provided the scans meet PCI DSS criteria.

Annual Scanning Misconception:

While annual compliance reports may include details of scanning activities, the requirement for internal scans is at least quarterly and event-triggered, not annually.

Reference Verification:

Requirement 11.3.1 (PCI DSS v4.0): Clearly outlines the need for quarterly scans and post-significant-change scans​​.

ROC and SAQ Templates: Reinforce the requirement that scans are both regular and reactive to environmental changes​​.

Customized Approach Overview:

Under PCI DSS v4.0, entities can use a Customized Approach to meet requirements by implementing controls tailored to their environment. This allows flexibility while still achieving the intent of the security requirement.

Role of Assessors:

Assessors (QSAs) are responsible for evaluating both the implementation of customized controls and ensuring these controls fulfill the security objectives of the PCI DSS requirements​​.

QSAs must document the evaluation, evidence reviewed, and results in the Report on Compliance (ROC).

Controls Matrix and Targeted Risk Analysis (TRA):

The Controls Matrix and TRA are key components of the Customized Approach. QSAs assist in verifying the accuracy and completeness of these tools during assessments​​.

Documenting in the ROC:

The ROC must include a narrative explaining the assessor’s findings regarding the customized control, validation methods, and any evidence collected​.

Relevant PCI DSS v4.0 Guidance:

Appendix D and E of the PCI DSS v4.0 ROC Template emphasize that QSAs can evaluate and confirm adherence to the Customized Approach provided this is documented comprehensively in the ROC​.

Requirement Context:

PCI DSS Requirement 12.5 mandates that security policies and operational procedures are not only documented but also distributed to relevant parties to ensure clarity and compliance.

Importance of Distribution and Awareness:

All affected parties, including employees, contractors, and third parties with access to the cardholder data environment (CDE), must receive and understand the policies. This ensures they adhere to the security measures​​.

Review and Updates:

Security policies must be kept up to date and reviewed at least annually or after significant changes in the environment. While other options such as encryption or restricted access are important for security, the critical focus is on distribution and awareness to ensure operational effectiveness​​.

Testing and Validation:

During assessments, QSAs validate the implementation by examining training records, communication logs, and acknowledgment forms signed by affected parties​​.

Relevant PCI DSS v4.0 Guidance:

Section 12.5.1 of PCI DSS v4.0 outlines that the dissemination of policies must ensure that all personnel understand their roles in securing the environment​​.
