What should the physical security plan include according to CIP-006 R1?

The requirement in CIP-006 R1 emphasizes the need for effective physical security measures to protect critical infrastructure. Specifically, it mandates that the physical security plan must include provisions for monitoring activities such as intrusion detection. This is crucial because intrusion detection systems are essential for identifying and responding to unauthorized access or security breaches in a timely manner. By monitoring for intrusion, the organization can detect potential threats as they arise, which helps to safeguard sensitive areas and assets within the facility.

While digital security measures are important, the focus of this specific requirement is on physical security. Notification protocols for cyber incidents and annual safety training for staff, although relevant to overall security and operational safety, do not specifically align with the requirements outlined in CIP-006 R1 for physical security. Hence, including monitoring for intrusion detection directly addresses the objectives of this requirement, making it the correct choice.
