What does CMS 25MC record?

The CMS 25MC form is specifically designed to record the destruction of multiple-copy segments of COMSEC (Communications Security) keymat. This form is critical in managing the lifecycle of key management materials, ensuring compliance with security protocols and regulations.

Using this form helps maintain accountability and traceability in the destruction process, thereby preventing unauthorized access to sensitive materials. Accurate recording also aids in verifying that the destruction was carried out appropriately and in accordance with established procedures.

In contrast to the other options: the destruction of single-copy segments of COMSEC keymat is documented on a different form; encryption of keymat would pertain to the processes involved in securing the information rather than recording destruction; and storage of keymat focuses on how and where key materials are kept, rather than their destruction. Hence, the correct choice aligns with the specific intended use of the CMS 25MC form in the context of keymat management.
