The organisation keeps written, approved standards, policies and procedures for audit and assurance in force, makes them known to the people they bind, applies them in practice and checks that they work. It revisits and refreshes them every year as a minimum, and again whenever a significant change occurs.
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.
