The commit passed. The pipeline roared forward. No one noticed the credentials embedded in plain text.
Pre-commit security hooks stop weak code before it reaches your repository. For AWS RDS, combining these hooks with IAM Connect removes static passwords from the equation entirely. Instead of storing keys or secrets, you give developers secure, short-lived tokens tied to their identity. Each database request is verified, authorized, and logged by AWS.
A pre-commit security hook can run locally, right before git commit executes. It scans staged changes for banned patterns: plaintext passwords, hardcoded AWS access keys, insecure SQL queries. With IAM Connect, the hook can enforce connection strings that rely on AWS IAM authentication. This ensures that every database connection uses policies and roles, not static credentials.
AWS RDS supports IAM database authentication for MySQL and PostgreSQL. The hook validates that your application code calls rds-support-iam libraries or uses the AWS CLI to generate temporary auth tokens. You can also integrate secret-scanning tools like gitleaks or detect-secrets directly into the hook script. The result is a guardrail before code reaches a shared branch.
