Why Use Terrascan IaC Security in Your Workflow?

• Prevents Misconfigurations – Detects and flags insecure IaC configurations.
• Automated Security Checks – Reduces manual security validation efforts.
• Seamless Pipeline Integration – Works with CI/CD tools for secure deployments.
• Early Risk Detection – Identifies potential security threats before provisioning.

Terrascan IaC Security Architecture

The modular architecture of Terrascan Security enables flexible policy enforcement across various IaC frameworks.

Core Components:

• CLI – Provides command-line execution for IaC scans.
• API Server – Supports integration with external security tools.
• Runtime – Handles validation and execution of security policies.
• IaC Providers – Converts infrastructure code into a standardized JSON format.
• Policy Engine – Evaluates IaC security compliance against defined policies.
• Notifier – Sends alerts via webhooks to security teams.
• Writer – Generates reports in JSON, YAML, and XML for compliance tracking.

Using Terrascan IaC Security Effectively

To analyze your IaC configurations, navigate to the target directory and run:

terrascan scan -t <iac_type> -d <directory_path>

Where:

• <iac_type> = Type of IaC (e.g., Terraform, Kubernetes, CloudFormation).
• <directory_path> = Path to IaC files.

The scan generates a security report, flagging policy violations and security risks that need remediation before deployment.

Key Benefits of Terrascan IaC Security

• Early Threat Detection – Identifies security risks before infrastructure deployment.
• CI/CD Automation – Works with Jenkins, GitHub, GitLab, and Azure DevOps for seamless security validation.
• Policy Compliance – Ensures alignment with CIS benchmarks, NIST, and regulatory requirements.
• Customizable Reporting – Exports results in JSON, YAML, and XML formats for integration into security workflows.
