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
- Access limited by physical location rather than by authorization
- Authorization not revoked when roles change
- Backup media accessible to general operations staff
