Prior to reusing Cyber Assets, what must be done regarding data on the storage media?

The requirement that relates to reusing Cyber Assets centers around the need to ensure that any data on the storage media is appropriately safeguarded against unauthorized access. This means that before Cyber Assets can be reused, measures must be in place to prevent unauthorized retrieval of the data stored on them.

In the context of NERC CIP standards, safeguarding data is critical due to the sensitive nature of the information handled by critical infrastructure facilities. Ensuring that data cannot be accessed or retrieved without appropriate authorization helps maintain the confidentiality, integrity, and availability of that information, which is essential for protecting against potential cyber threats.

The other options either do not address the specific need for securing data against unauthorized access or suggest actions that might lead to potential vulnerabilities. For instance, transferring all data to another facility may not always be practical or necessary, leaving data intact could pose risks of unauthorized access, and simply archiving data does not prevent it from being retrieved without authorization. The focus of NERC CIP standards is on preventing unauthorized data access as a key measure in asset management and cybersecurity protocols.
