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
- Local administrators able to clear logs without trace
- Log integrity protection absent
- Logging tool configuration modifiable by general administrators
