First move
Start with the 1 of 3 artefacts that already live in a system (SIEM / log platform); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- maintenance treated as routine and never monitored
- risk learned during maintenance never shared
