The controller must choose the most appropriate storage location: in a controlled environment, templates should sit on a device kept by and under the sole control of the user (a smartphone or ID card) or, where objectively needed, in a central database encrypted with a key held solely by the person; if the controller cannot avoid access to templates, it must secure them, for instance by encryption.
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.
