Critical security parameters such as usernames and passwords, API keys or private keys are not hard-coded in the device software source code, since reverse engineering finds them readily and obfuscation is easily broken. Status in Table B.1: M (mandatory, a shall provision).
This control maps to 2 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 2 it maps to, and the evidence behind each claim, over MCP and REST.
