Extends ISO/IEC 27002:2013 18.2.1. Where auditing by individual customers is impractical or could add security risk, the processor offers prospective customers, before the contract and for as long as it runs, independently produced evidence that its security is put in place and run the way its own policies and procedures require. An appropriate independent audit chosen by the processor should normally satisfy a customer's interest in reviewing the processing, provided it is transparent enough.
This control maps to 4 controls across 4 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 4 it maps to, and the evidence behind each claim, over MCP and REST.
