DevSecOps Week 3 – Enforcing Terraform Security with OPA (Policy as Code Pipeline)

In Week 3 of this DevSecOps project, we move beyond security scanning and into true enforcement using Policy as Code. In previous weeks: Week 1 We built a secure CI/CD pipeline with: Unit tests Static code analysis Dependency vulnerability scanning Container image scanning Week 2 We implemented Infrastructure as Code using Terraform with: Secure VPC architecture ECS Fargate container runtime ALB load balancing IAM least privilege CloudWatch logging Infrastructure security scanning with tfsec and Checkov Week 3 Focus: Policy Enforcement In this week we implement Governance and Policy as Code using: • Open Policy Agent (OPA) • Rego security policies • Conftest Terraform validation • GitHub Actions enforcement pipeline Instead of only detecting security issues, we block insecure infrastructure before deployment. The pipeline now enforces rules such as: 🚫 Block public SSH access (port 22 from 0.0.0.0/0) 🔐 Enforce S3 encryption with SSE-KMS 🚫 Prevent public S3 bucket exposure 🔒 Enforce HTTPS with valid TLS certificates on the ALB If any policy fails: ❌ The pipeline fails ❌ Terraform cannot deploy ❌ The pull request cannot be merged This is how production DevSecOps platforms enforce security automatically.
