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
- Deletion at the file system level treated as secure disposal
- Cloud storage disposal assumed from the provider with no evidence
- No record linking disposed media to the data it held
