First move
Start with the 1 of 4 artefacts that already live in a system (Cloud console / configuration management); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Flat VNet topology
- Default-allow NSG rules
- No micro-segmentation for sensitive workloads
