Systems have a system security plan that includes an overview of the system (covering the system's purpose, the system boundary and how the system is managed) as well as an annex that covers applicable controls from this document and any additional controls that have been identified and implemented.
This control maps to 3 controls across 2 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 3 it maps to, and the evidence behind each claim, over MCP and REST.
