First move
Automate the pull from your Cloud console / configuration management. Configuration snapshots and change history from the cloud console or IaC repository, diffed against the baseline.
Common gaps auditors find
- Some systems using a different or default time source
- Time zone handling inconsistent across log sources
- Drift unmonitored, so correlation quietly degrades
