First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Assessment performed by the team that operates the controls, with no independence
- Plan approved after testing had already started, or not at all
- Report produced but findings never routed into remediation tracking
