First move
Start with the 2 of 5 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
- SaaS and PaaS logs not piped to the SIEM
- Timestamp skew across sources defeats correlation joins
- Identity provider logs not joined to endpoint telemetry
- Enrichment relies on stale threat feeds
