📚 Part of the Cloud Performance Testing & IaC Security Guide series.
Infrastructure as Code lets a single misconfigured module provision an insecure resource hundreds of times. Securing IaC means catching those issues before apply — in the plan, in the pipeline, and in policy. This hub links the pieces of a secure IaC workflow.

The secure IaC workflow
- Write securely — secure module defaults, no hardcoded secrets, least-privilege IAM. See Terraform Security Best Practices.
- Scan in the pipeline — static analysis (tfsec/Checkov), plan review, and policy-as-code gates. See the CI/CD Pipeline Security Workflow and DevOps CI/CD Security Complete Guide.
- Manage drift & exposure — detect drift, track known issues. See Vulnerability Management.
Plan-review checklist
- No public exposure introduced (open security groups, public buckets).
- Encryption at rest and in transit on every data resource.
- IAM changes are least-privilege and reviewed.
- No secrets in state or variables; remote state is encrypted and access-controlled.
- Policy-as-code (OPA/Sentinel) passes before apply.
