First move
Start with the 2 of 5 artefacts that already live in a system (Identity provider / directory); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Emergency maintenance performed without retrospective documentation
- Maintenance vendors lack signed confidentiality and security clauses
- Vendor engineers granted standing access rather than session based access
