First move
Start with the 1 of 3 artefacts that already live in a system (Cloud console / configuration management); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Endpoint encryption in place while servers and shares are unprotected
- Storage locations for CUI never fully inventoried
- Cloud storage protection assumed from the provider without verification
