Security policies and operational procedures should be?

 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​​.
