The organization sets up, runs and maintains processes for checking whether its compliance obligations are met. It decides how often compliance is checked, carries out the checks and acts where needed, and keeps itself informed of where it stands on compliance. Documented information is kept to evidence what each compliance evaluation found.
This control maps to 13 controls across 11 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
