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
- Exemption applied to media that regularly leaves the controlled area
- Markings applied at creation but lost when media is copied or reused
- Classification scheme exists but staff cannot tell which marking to apply
