All custom device requirements, derived and non-derived alike, are validated through the DO-254 Section 6 validation process, because requirements refined, decomposed or restated at device level must also be correct and complete; for DAL A and B the validation is done with independence (Appendix A of DO-254 gives acceptable means).
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.
