What does CIP-006 R3 require from Responsible Entities regarding physical access control?

CIP-006 R3 specifically requires Responsible Entities to implement a maintenance and testing program for physical access controls. This requirement is designed to ensure that physical access controls are not only established but also maintained effectively over time. The maintenance and testing program is critical for assessing the effectiveness of the physical access control measures in place, identifying any weaknesses, and ensuring that these controls continue to meet security requirements.

By instituting such a program, organizations can regularly evaluate and improve their security posture, responding proactively to any potential vulnerabilities or changes in the threat landscape. This ongoing vigilance is a key aspect of maintaining robust physical security and protecting critical infrastructure.

The focus of the requirement is on the operational aspect of physical security, contrasting with other options that may not specifically address the need for ongoing maintenance and testing of access controls, which is vital for compliance with CIP standards.
