What is required at least once each calendar quarter under CIP-004 R4.2?

Under CIP-004 R4.2, the requirement for a verification of authorization records at least once each calendar quarter is crucial for maintaining an effective security posture. This requirement is focused on ensuring that access to critical cyber assets is appropriately controlled and that individuals who have access are continuously authorized based on their roles and responsibilities. Regularly verifying these records helps organizations identify and address any discrepancies or unauthorized access, reinforcing the integrity of their security measures.

By adhering to this quarterly verification, entities can ensure that only the right individuals have access to sensitive systems and data, which is essential for mitigating risks associated with insider threats and unauthorized access. Regular reviews foster accountability and support compliance with security policies and standards, making it vital for the safety of critical infrastructure.

The other options — while important in their own contexts — do not reflect this specific requirement outlined in CIP-004 R4.2, which underscores the need for regular verification of who is allowed access to critical cyber assets. This focus on authorization verification is key to effective cybersecurity governance under the CIP standards.
