Visitors. Level 1 (a to e): visitors escorted by authorised personnel; visitors distinguishable from on-site personnel by pass or badge; a visitor log kept; the visitor log reviewed; and publicly accessible network points restricted. Level 2 adds management approval for visitor access to sensitive areas; Level 3 is the same.
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.
