Debug interfaces that are physical ports are physically protected by the device, for example by a casing that must be opened with tools or broken to reach a UART; a disabled interface needs no physical protection. Status in Table B.1: R F (r) (recommendation, a should provision; applies only where physical-port debug interfaces exist).
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.
