ISO 27001 Annex A 8.25: Secure development life cycle
Quick answer
ISO 27001 Annex A 8.25 (Secure development life cycle) is a technological control. Apply rules for the secure development of software and systems.
What auditors look for
Auditors check that 8.25 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:
- Secure development policy
- Security activities in the SDLC
- Evidence such as reviews and scans
How to implement 8.25 in practice
- Add threat modelling to design
- Automate security testing in pipelines
- Train developers in secure coding
- Name an owner for 8.25, decide how often it runs and file evidence each time, so the control is audit-ready all year.
Recording 8.25 in the Statement of Applicability
List 8.25 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.
