BSI C5 · Control DEV-02 · Priority: high · Component: Development & Change Management

### What this control covers

Contractually specifies security requirements for outsourced development, including standards compliance, acceptance testing, and vulnerability verification. Ensures third-party deliverables meet CSP security standards, protecting cloud customer data integrity.

### Why it matters

Cloud misconfiguration is the leading cause of cloud-related breaches; posture management is how you catch it before someone else does.

### How to implement

#### AWS

Manage all changes in **Terraform/CloudFormation**; enforce SCPs that deny console writes for prod. Use **AWS Config rules** + **conformance packs** (CIS, HIPAA, PCI) to detect drift.

#### Azure

**Azure Policy** + **Blueprints** baseline landing zones; Bicep/Terraform as IaC and **Policy Insights** for drift.

#### GCP

**Org Policy Service** for guardrails and **Config Validator** in CI to pre-check Terraform plans against policy as code (Rego).

#### GitHub

Apply **branch protection** on default and release branches: require PR review, status checks, signed commits, linear history, and dismiss stale reviews on new commits. Use **CODEOWNERS** for required reviewers, **Dependabot** + **CodeQL** for SAST, and the **Dependency graph / SBOM** export for vendor disclosures.

### Evidence to collect

-   `vendor_risk_management` — See the iCompaas Evidence library for the canonical source for this evidence type.
-   `infra_scan` — See the iCompaas Evidence library for the canonical source for this evidence type.

Third-party risk management evidence (assessments, contracts, due diligence) shows supplier oversight. Focus: Outsourcing of the development.

### Quick checklist

-   Risk — Cloud Customer Data / Development
-   Review — Cloud Customer Data / Development
-   Verification — Cloud Customer Data / Development
-   Security — Cloud Customer Data / Development
-   Data — Cloud Customer Data / Development
