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
- Clock drift across hosts breaks event correlation
- Privileged user activity not isolated for independent review
- Critical log sources missing from the SIEM with no detection coverage
Do this for your whole sheet
Paste the rows you run your controls from and get this mapping for every control at once, with the periodic-review ones flagged and a first move per row. No account for the first run.
