According to CIP-009 R2, how often must recovery plans be implemented and tested?

CIP-009 R2 specifically mandates that recovery plans should be implemented and tested at least once every 15 calendar months. This frequency ensures that organizations maintain a current and effective response capability for potential cybersecurity incidents that could disrupt their operations. By conducting tests within this timeframe, entities are encouraged to regularly evaluate their plans, incorporate improvements, and adapt to changes in the threat landscape, technologies, or business operations.

Implementing and testing recovery plans beyond this timeframe, such as annually or biennially, may not provide sufficient assurance that the plans remain effective or relevant to new risks or operational shifts. The rule helps organizations ensure that their recovery strategies are continually validated and improved, ultimately enhancing their resilience against potential cybersecurity threats.
