What does CIP-009 R2.2 specifically state should be tested at least once every 15 calendar months?

The reason that a representative sample of recovery information should be tested at least once every 15 calendar months, as specified in CIP-009 R2.2, is tied to the importance of ensuring the effectiveness of the recovery plans in place for critical infrastructure. This requirement emphasizes the need for organizations to validate that their recovery strategies are not only up-to-date but also effective when a real incident occurs.

By testing a representative sample, organizations can identify potential weaknesses in their recovery processes and make necessary adjustments. This proactive approach helps to ensure that the organization is prepared to restore operations and maintain reliability during and after disruptive events. Conducting these tests at least once every 15 calendar months ensures ongoing compliance and readiness, confirming that the recovery information remains relevant to current operational contexts and technological changes.

The focus on recovery information aligns with broader objectives within the NERC CIP standards, where maintaining security and reliability of the electric grid is imperative. Regular testing within the defined timeframe supports continuous improvement of plans and prepares staff for effective implementation if a recovery situation arises.
