Every certificate the 3DS Server, ACS and DS present to one another comes from a certificate authority that can be trusted. The assessor examines evidence of CA validation (such as security assessments or certifications) and observes the certificates in use.
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.
