Infrastructure as Code (IaC) scanning tools analyze IaC templates, configurations, and scripts for misconfigurations, security vulnerabilities, compliance violations, and best practice deviations. These tools improve reliability and prevent security breaches by detecting issues before infrastructure is deployed. IaC scanners can be categorized into linters, static code analysis tools, vulnerability scanners, and static application security testers. Some popular IaC scanning tools include Checkov, Trivy, TFLint, Kubescape, KICS, GitLab Infrastructure as Code scanning, Spectral, and Spacelift. Each tool offers unique features, pricing models, and support for various IaC platforms. To effectively use IaC scanning tools, integrate them into your development process, enforce scans as part of your CI/CD pipeline, and consider using a platform like Spacelift to manage cloud resources and ensure compliance.
