How frequently must the identifications in Requirement R1 be reviewed according to CIP-002 R2.1?

The requirement specifies that the identifications must be reviewed at least every 15 calendar months according to CIP-002 R2.1. This timeframe ensures that organizations remain vigilant and proactive in identifying and assessing the critical assets, systems, and facilities that are essential to the reliable operation of the Bulk Electric System (BES). The 15-calendar-month interval provides flexibility in scheduling while still maintaining an appropriate level of ongoing oversight and evaluation.

This periodic review process is important as it allows organizations to take into account any changes in their operational environment, technology, regulatory landscape, or business processes that could affect their security posture. By adhering to this specific timeframe, companies can ensure they are continuously aligned with the NERC CIP standards, minimizing risk and enhancing overall security.
