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
- Inconsistent log collection across systems
- Insufficient protection of log integrity
- Irregular or undocumented log review
- Retention periods not aligned with policy
