The operator must use suitable measures, such as signs placed before the monitored area is entered, so that people can see, at the earliest possible moment, that they are being observed and who the controller is, with the controller's name and how to contact it.
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.
