What does Requirement 12 emphasize regarding personnel?

Requirement 12 of the PCI DSS focuses on the importance of implementing and maintaining an information security policy for all personnel associated with an organization. This requirement underscores the need for a strong, comprehensive security posture that informs employees about security practices, their responsibilities, and the organization's guidelines for protecting sensitive information.

By maintaining a policy that addresses information security for all personnel, organizations ensure that everyone understands the security protocols and their role in safeguarding cardholder data. This includes training on security awareness, incident reporting, and compliance with security measures, ultimately fostering a culture of security within the organization.

The emphasis on a security policy highlights the proactive approach organizations must take to mitigate risks associated with human behavior and ensure that all staff members are aware of their obligations.
