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
- Media awaiting destruction accumulates in unsecured areas for months
- Custody records absent, so loss would not be detected
- Sanitisation performed with a quick format rather than an approved technique
