Password Rotation Policies in Infrastructure as Code

Keys expire. Systems break. Secrets leak.

If you manage infrastructure as code (IaC), password rotation policies are not optional. Static credentials are security debt that grows fast. Without enforced rotation, a single compromised key can expose everything you built.

Password rotation policies in IaC mean setting automated, immutable rules in your codebase that refresh credentials on a strict schedule. No manual updates. No hidden exceptions. This removes human error and aligns security with the same version-controlled, repeatable processes that IaC brings to infrastructure.

The baseline: rotate passwords and API keys every 30, 60, or 90 days depending on risk. Store them in a managed secrets vault. Use environment variables injected at runtime, not committed to git. Write Terraform or CloudFormation that reads these values from the vault and replaces them in deployments. Make rotation automatic, triggered by code changes, CI/CD pipelines, or vault policy rules.

Integrate rotation policies into IaC modules so they apply consistently across all environments. Use tagging, naming conventions, and outputs to track which secrets are active. Deploy monitoring to detect credentials past their expiry date. Enforce failure states if outdated credentials are in use.

Provisioning new passwords should be atomic and reversible. When rotation runs, both old and new credentials should exist in a transient overlap to prevent downtime, and old credentials should automatically revoke after the overlap window closes.

Password rotation is not a one-time setup. You must test it. Run simulated breaches. Confirm that unauthorized credentials fail fast and alert you. Keep rotation logic in source control so every change is reviewed, merged, and logged.

Infrastructure as code is only as secure as the secrets it manages. If your password rotation policies are weak, your IaC templates become blueprints for compromise. Done right, automated rotation is a fast, predictable shield that closes the window of opportunity for attackers.
