What does CIP-006-6 specify regarding the physical security of BES Cyber Systems?

The requirement regarding the physical security of Bulk Electric System (BES) Cyber Systems as outlined in CIP-006-6 specifically mandates the implementation of a physical security plan. This standard emphasizes the need for entities to develop and enforce a comprehensive physical security strategy that protects their Critical Cyber Assets (CCAs) from unauthorized physical access, tampering, damage, or other physical threats.

By having a physical security plan in place, organizations can ensure that appropriate measures, such as controlled access points, surveillance, and other security controls, are implemented to maintain the integrity and availability of their cyber systems. The focus on having a structured plan enhances the overall security posture of the assets essential to the reliable operation of the electric grid.

Other choices do not capture the essence of CIP-006-6. While risk assessments, software vulnerabilities management, and user access privileges are important aspects of cybersecurity, they are addressed in different standards or requirements within the NERC CIP framework, but not specifically within CIP-006-6, which is centered on physical security measures.
