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
- Controls applied to production information while design and procurement documents naming weaknesses circulate freely
- Job advertisements, supplier lists and conference material disclosing architecture with no operations security review
- Applied at development only, with disposal and decommissioning uncovered
