First move
Start with the 4 of 12 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
- Retaining data beyond approved period
- No evidence of secure erase verification
- Policies not aligned with actual practice
- Incomplete media disposal records
