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
- IDS deployed but alerts never routed to an analyst
- default rule set never tuned so alerts are ignored
- encrypted traffic paths not inspected and not compensated
