Scans are carried out by qualified people: the external ones by an Approved Scanning Vendor listed by PCI SSC, the internal ones by competent staff. The assessor checks the scan reports and asks who ran them.
This control maps to 2 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 2 it maps to, and the evidence behind each claim, over MCP and REST.
