For CONFIDENTIAL, SECRET and TOP SECRET systems, if a speakerphone will be used on a secure telephone system inside a secure area, agencies must ensure: (1) it sits in a room rated as audio secure; (2) the room stays audio secure throughout any conversation; (3) only cleared personnel taking part in the discussion are in the room; and (4) the Accreditation Authority has approved this exception.
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.
