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
- Thresholds set so wide that a genuine excursion never raises an alarm
- Alarms routed to a mailbox that nobody watches outside working hours
- Sensing limited to room level so rack level hot spots go undetected
- No record of the corrective action that followed a logged excursion
