What is Secret Rotation?
The practice of periodically replacing secrets with new values to limit the impact of compromises.
Definition
Secret rotation is the process of periodically replacing credentials with new ones. This limits the window of exposure if a secret is compromised: even if an attacker obtains a key, it becomes invalid at the next rotation. Automated rotation updates the secret in all locations (secret manager, cron job configs, endpoints) simultaneously, while manual rotation requires coordinated updates to prevent downtime.
Simple Analogy
Like changing the locks on your house periodically — even if someone made a copy of your key, the old key stops working after you change the locks.
Why It Matters
Secrets can be exposed through log files, browser history, insider threats, or supply chain attacks. Without rotation, a compromised secret provides indefinite access. Regular rotation limits the damage: an old key found in a log file from six months ago is useless if the key has been rotated since then.
How to Verify
Check when each secret was last rotated. Review your secret manager's rotation history. Verify that old secrets have been invalidated (not just supplemented with new ones). Test that services continue working after rotation without manual intervention.
Common Mistakes
Rotating the secret in the producer but not the consumer, causing authentication failures. Not testing the rotation process before doing it in production. Keeping old secrets active "just in case," negating the security benefit of rotation. Not automating rotation, leading to it being skipped.
Best Practices
Automate secret rotation with zero-downtime deployment: add new secret, update consumers, then revoke old secret. Rotate at least quarterly, or immediately after any suspected compromise. Test the rotation process in staging first. Use CronJobPro's API to update job credentials programmatically during rotation.
