Signing, verification and transport of updates rely on best practice cryptography: the device uses it to support its secure update mechanism, for example in signing, verification and transport of update packages. Status in Table B.1: M F (g) (mandatory, a shall provision; applies only where the device's software can be updated).
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.
