Every API that interfaces with the 3DS environment is identified, has its definition documented and is tested to confirm it behaves as expected. The assessor examines network and data-flow diagrams, observes the controls, examines test results and interviews personnel.
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.
