First move
Start with the 4 of 12 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
- outdated topology diagrams
- inconsistent firewall rule documentation
- missing periodic review of ACLs
- weak wireless encryption settings
