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
- Segmentation flat across business units
- Firewall rules grow without rationalization
- Attack surface assets unknown
- Effectiveness testing never performed
