Securing the Cloud Control Plane: A Practical Guide to Secure IaC Deployments

Infrastructure as Code (IaC) has become the control plane of modern cloud environments, and a prime attack surface. Misconfigured Terraform templates, overprivileged IAM roles, exposed state files, and insecure CI/CD pipelines can lead to full cloud compromise in minutes. This guide explains how to secure IaC deployments end-to-end using static code scanning, policy-as-code enforcement, short-lived federated identities, least-privilege IAM, encrypted remote state, and continuous drift detection. The core idea: secure infrastructure before it’s deployed, not after it’s breached.
