Configures tfsec for Terraform-specific security scanning - covers AWS / Azure / GCP / Kubernetes / OpenStack / Oracle / DigitalOcean / CloudStack, custom YAML rules, and SARIF / JUnit / Markdown output. Note: tfsec is transitioning to Trivy per Aqua Security, so new projects evaluate that first. Use for an existing Terraform-only tfsec stack; for the consolidated forward-path scanner use trivy-config, for the broadest multi-framework checks use checkov-policy, and for wider platform breadth use kics-policy.
