For CONFIDENTIAL, SECRET and TOP SECRET systems, trusted sources must: form a strictly limited list drawn from business requirements and the results of a security risk assessment; hold an appropriate security clearance where needed; and have Accreditation Authority approval.
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.
