ISO 27001 Annex A 8.19: Installation of software on operational systems
Quick answer
ISO 27001 Annex A 8.19 (Installation of software on operational systems) is a technological control. Manage software installation on operational systems securely.
What auditors look for
Auditors check that 8.19 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Software installation policy
- Approved software list
- Application control settings
How to implement 8.19 in practice
- Remove local admin rights from users
- Use a self-service catalogue of approved apps
- Monitor for unapproved software
- Name an owner for 8.19, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 8.19 in the Statement of Applicability
List 8.19 with whether it applies, the reason (usually the risks it treats or a legal or contractual requirement), its implementation status and where the evidence lives. If you exclude it, explain why none of your risks or obligations require it.
