ISO 27001 Annex A 8.30: Outsourced development

What auditors look for

Auditors check that 8.30 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:

• Contracts with security requirements
• Code review or test evidence from suppliers
• Acceptance testing records

How to implement 8.30 in practice

1. Set security requirements in contracts
2. Retain code ownership and access
3. Test delivered code yourself
4. Name an owner for 8.30, decide how often it runs and file evidence each time, so the control is audit-ready all year.

Recording 8.30 in the Statement of Applicability

List 8.30 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.
