First move
Automate the pull from your SIEM / log platform. Retention and alert rules exported from the SIEM; review evidence is the closed-alert record with reviewer and time.
Common gaps auditors find
- Retention configured shorter than the policy states
- Logs protected in the central store while copies at source are unprotected
- Retention never verified, so silent truncation goes unnoticed
