ISO 27001 Annex A 8.31: Separation of development, test and production environments
Quick answer
ISO 27001 Annex A 8.31 (Separation of development, test and production environments) is a technological control. Separate and secure development, test and production environments.
What auditors look for
Auditors check that 8.31 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Environment architecture
- Access controls per environment
- Deployment pipeline controls
How to implement 8.31 in practice
- Prevent developers from changing production directly
- Keep production data out of test
- Use separate accounts or projects
- Name an owner for 8.31, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 8.31 in the Statement of Applicability
List 8.31 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.
