The system documentation must contain the policy; the objectives and targets; an account of what the scope covers; an account of the system's main parts and how they link to related documents; the documents and records the Standard calls for; and any others the organization judges it needs to plan, run and control the processes tied to its significant risks.
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.
