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
- Only aggregated dashboards exist and the underlying records cannot be retrieved
- Normalisation rewrites timestamps into local time and loses the original ordering
- Reduction pipeline drops fields permanently rather than filtering a preserved copy
