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
- Broad administrative roles granted because scoped roles were never built
- Permissions granted for a one-off task and never withdrawn
- No measurement of granted versus actually used access
