What standard does CIP-004 R4.2 ensure regarding individuals with active access?

CIP-004 R4.2 focuses on ensuring that individuals with active access to the critical infrastructure systems have their authorization records verified. This requirement is crucial as it aims to maintain the integrity and security of the systems by confirming that those who have access are indeed authorized individuals who meet the necessary criteria for access.

By verifying authorization records, organizations can ensure that only qualified personnel have access to sensitive systems, thus minimizing potential security risks. This process helps in identifying any discrepancies in access controls, allowing for timely remediation of any unauthorized access, which is vital for maintaining the overall security posture required by the NERC CIP standards.

The other options, while important in their own right, do not align with the specific focus of R4.2. Regular performance reviews, participation in drills, and ensuring training is up to date are all valuable practices, but they do not directly address the verification of authorization records as mandated by this requirement. This distinction helps organizations maintain not only compliance but also a secure operational environment.
