Mostly documents and reviews. Pull the 1 system-held artefact from your SIEM / log platform 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
- Inventory stale
- No annual count
- Discrepancies unresolved
