First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Threat modelling performed inconsistently across product teams
- Open source components used without SBOM or licence review
- Vendor SOC reports collected but exceptions not analysed
