FERC Order 791 is primarily concerned with the changes resulting in which version of the CIP Standards?

FERC Order 791 specifically addresses the revisions that resulted in the implementation of Version 5 of the NERC Critical Infrastructure Protection (CIP) Standards. This order was significant as it approved the changes made in Version 5, which introduced a variety of new requirements aimed at strengthening the security posture of the electric grid against cyber threats. Notably, these revisions focused on enhancing security measures surrounding the critical cyber assets, including aspects such as risk assessment and the protection of information systems.

While later versions, such as Version 6 and Version 7, have made further updates and refinements, Order 791 is particularly linked to the transition to Version 5, making it pivotal in the history of the NERC CIP standards journey. This context is essential to understand the evolution of cybersecurity frameworks within the electric sector and how regulatory measures like FERC orders shape these standards over time.
