First move
Mostly documents and reviews. Pull the 1 system-held artefact from your Identity provider / directory on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
Common gaps auditors find
- Privileged accounts shared across administrators without individual accountability
- Access reviews performed but exceptions never remediated
- Role definitions drift from documented matrix without change control
