First move
Start with the 1 of 4 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
- No FIM on critical ePHI stores
- Database triggers not monitored
- Tampering detection only via backups
