Where an agency relies on encryption so that IT equipment or media holding classified information can be stored or physically moved under lighter requirements, it should use either: full disk encryption; or partial disk encryption where access controls permit writes ONLY to the encrypted partition that holds the classified information.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
