How should a Responsible Entity approach the reuse of Cyber Assets according to CIP-011 R2.1?

A Responsible Entity should focus on preventing unauthorized information retrieval when considering the reuse of Cyber Assets as per CIP-011 R2.1. This requirement emphasizes the importance of safeguarding sensitive information that may remain on Cyber Assets, such as data, configurations, and credentials, before they are reused, reallocated, or disposed of.

By controlling access to and securing the data on these assets, the Responsible Entity can mitigate risks associated with potential data breaches or unauthorized access that could compromise the security of the Bulk Electric System. Ensuring that sensitive information is protected before any further use helps to maintain the integrity and confidentiality of critical infrastructure.

In contrast, publicly announcing the reuse plan would generally not align with the security objectives of preventing unauthorized access to sensitive data. Consulting external advisors may provide insights, but it does not directly address the core requirement of information protection related to the reuse process. Conducting software updates is a good practice, yet it alone does not guarantee protection against unauthorized retrieval of information on the Cyber Assets.
