A.8.30·medium·Component: Technological controlsWhat this control requires
The organization shall direct, monitor and review the activities related to outsourced system development.
In plain English
The organization shall direct, monitor and review the activities related to outsourced system development. In practice, this means you can prove you management management-level controls on a defined cadence.
Why it matters
ISO 27001 certification depends on showing each Annex A control is either implemented or explicitly justified for exclusion in the Statement of Applicability (SoA). Certification bodies sample controls during surveillance audits, and a missing SoA entry — or implementation that doesn't match the SoA wording — is a finding.
What an auditor looks for
An ISO 27001 lead auditor looks for: (1) an SoA entry covering the control with justification, (2) a documented procedure or policy implementing it, (3) records that prove the procedure runs (logs, tickets, training records) and (4) management-review evidence that effectiveness is monitored.
Within Technological controls, the assessor will trace your implementation back to the catalogue reference (Annex A A.8.30) and look for objective evidence on the latest two assessment cycles.
How to implement
Logging Monitoring
AWS. Org-trail CloudTrail to a central log archive account, GuardDuty in every region, and Security Hub for cross-source correlation.
Azure. Pipe every diagnostic setting into a central Log Analytics workspace; onboard Microsoft Sentinel for SIEM/SOAR.
GCP. Aggregate audit logs in a dedicated logging project with sink to BigQuery; enable Security Command Center Premium and route findings to Chronicle SIEM.
Secure Development
Pipeline. Require code review, SAST (Semgrep / Snyk Code), SCA (Dependabot / Renovate), secret-scanning and IaC scanning in the merge pipeline.
Branch protection. Protected branches enforce reviews, signed commits and passing CI before merge; document the protection rules as the control evidence.
Operational checklist
- Management. Document the trigger, the owner and the cadence.
- Secure. Document the trigger, the owner and the cadence.
- Security. Document the trigger, the owner and the cadence.
- Monitor. Document the trigger, the owner and the cadence.
- Scope: management, security, development.
Evidence to collect
- Ticketing Workflow.
ticketing_workflowevidence - Vendor Risk Management.
vendor_risk_managementevidence - Infra Scan. Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.
Vendor assessments and tracked deliverables demonstrate oversight of outsourced development.
Common pitfalls
- Per-account logging that nobody stitches together at the org level — incidents that cross accounts go undetected for days.
- CI security checks set to warn-only; the merge button is faster than the security feedback.
