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
- Installation restricted on endpoints while operational servers permit direct installation by administrators outside change control
- Software installed to resolve an incident and never brought back through change or documented
- No rollback capability, so a failed installation becomes an outage
- Supplier remote installation permitted with no record of what was installed or when
