PCI DSS Requirement 12.6 requires personnel to acknowledge at least _______________ that they have read and understood the security policy and procedures.

In the context of PCI DSS Requirement 12.6, personnel must formally acknowledge that they have read and understood the security policy and procedures at least annually. This annual acknowledgment helps ensure that all employees remain aware of the organization's security practices and any changes that might occur within the security policies.

Regularly revisiting security policies is critical for maintaining a strong security posture, as it reinforces the importance of compliance and helps mitigate risks associated with security breaches. By requiring this acknowledgment on an annual basis, organizations can ensure that personnel stay current with evolving threats, security best practices, and any updates to the policies themselves. This frequency supports an informed workforce that contributes to the overall security culture within the organization.
