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
- Matrix covering a subset of controls with the rest left undetermined
- Controls marked shared with no explanation of the split
- Matrix not updated after a service change altered the boundary
