Terrascan is a flexible and powerful open-source static code analysis tool designed for scanning infrastructure as code (IaC) templates and configurations, helping identify security vulnerabilities, compliance violations, and best practice issues. It can be used with multiple types of configuration files, provides built-in policies, and allows the use of custom policies using Rego. Terrascan helps developers and DevOps teams ensure that their infrastructure code adheres to best practices, security standards, and compliance requirements. The tool provides 500+ out-of-the-box policies so that users can scan IaC against common policy standards such as the CIS Benchmark. Terrascan aims to alert users to any compliance or security problems before the infrastructure is provisioned, allowing them to remedy them and avoid issues. The tool supports multiple IaC frameworks, including AWS, Azure, Google Cloud Platform (GCP), K8S, ArgoCD, Atlantis, GitHub, and Docker, making it versatile for cross-cloud infrastructure deployments. Terrascan can be integrated into CI/CD pipelines, IDEs, and other development and deployment workflows for automated scanning and validation of IaC code. It also provides continuous monitoring of cloud infrastructure and generates detailed reports that highlight issues found during the analysis, along with guidance on how to remediate them. Terrascan can be installed using popular package managers such as Chocolately or by downloading and extracting the files manually. The tool has a user-friendly interface and allows users to scan their code, customize policies, and exclude specific rules from the scan. Terrascan is compared to other similar products like Chekov and TFSec, with its unique features and strengths making it a popular choice among developers and DevOps teams.
