IaC security scanning uses static analysis to detect misconfigurations in Terraform, Kubernetes, and other infrastructure files before they reach production. Common issues caught include exposed S3 buckets, overly permissive IAM roles, open network ports, missing encryption, and privileged containers. Popular open-source tools include Checkov, Terrascan, and Trivy. Scanning should be integrated at multiple SDLC stages: developer workstations, pre-commit hooks, and CI/CD pipelines, with Git as the central control plane. IaC scanning has limits — it cannot detect runtime drift or manual console changes — so it should be paired with CSPM for full coverage. Commercial platforms add AI-driven AutoFix and centralized dashboards to accelerate remediation.
