First move
Start with the 1 of 4 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
- Administrator rights granted as a default to speed up troubleshooting and never revoked
- Service accounts run with far more privilege than the application needs
- Least privilege applied to people while automation and pipeline identities are unrestricted
