Pre-commit Security Hooks for Terraform

The code waits. One wrong commit could expose secrets, misconfigure infrastructure, or open a security gap you never see until it’s too late.

Pre-commit security hooks for Terraform stop these mistakes before they land in your main branch. They run automatically when you stage changes, scanning your .tf files, modules, and variable definitions for risks. No pipeline delays. No hidden problems. Just immediate feedback.

A strong pre-commit setup checks for hardcoded credentials, insecure resource configurations, and dangerous defaults. It can enforce policies like data encryption, restricted network exposure, and IAM role limitations. For Terraform, that means controlling changes to AWS security groups, blocking public S3 buckets, or flagging unencrypted RDS instances before they ever hit terraform apply.

Integrating pre-commit hooks is simple. You define rules in a .pre-commit-config.yaml file and connect them to security-focused tools. Popular options include tflint for linting and best practices, terraform validate for syntax and schema errors, and custom scripts that scan for sensitive values. Version control integration ensures these checks run locally for every developer, before commit, in seconds.

Security hooks work best when part of a layered defense. Combine them with CI/CD security tests, Terraform Cloud or Sentinel policies, and code review processes. But pre-commit is where speed meets precision: it catches the issue in front of the person who just wrote it, reducing fix time to near zero.

Every Terraform project benefits from this guardrail. Whether maintaining a single VPC or orchestrating hundreds of microservice environments, pre-commit security hooks keep infrastructure code clean, compliant, and safe from costly errors.
