Which of the following is a requirement for the Access Revocation aspect of CIP-004?

The requirement for the Access Revocation aspect of CIP-004 centers around having documented access revocation programs. This is essential because the CIP-004 standard emphasizes the need for robust processes related to granting, managing, and revoking access to Critical Cyber Assets. Proper documentation of access revocation procedures is crucial for ensuring that when an individual's access to critical systems or data is no longer needed—whether due to termination, role changes, or other factors—this access can be effectively and securely revoked in a timely manner.

Having a structured program in place not only helps in maintaining security by ensuring that only authorized personnel have access to sensitive systems but also supports accountability and compliance with regulatory requirements. This documentation serves as a reference for training, audits, and security assessments, reinforcing the overall integrity of the organization’s cybersecurity posture.

The other options, while valuable, do not specifically address the needs related to access revocation as mandated by the CIP-004 standard. Therefore, the emphasis on documented access revocation programs is what makes this choice the right answer.
