First move
Start with the 2 of 5 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
- WPA PSK in use for CDE traffic
- WEP enabled on legacy AP
- No EAP authentication
