If the service continues to use an old secret in memory, it means it has not updated the configuration or not restarted the relevant components after secret rotation.
How to fix:
-
Ensure proper secret updates at runtime. Use mechanisms for dynamic configuration or secret loading without restarting the service.
-
Restart the service or its components that cache secrets. Sometimes it's easier to restart the service so it reads the new secrets.
-
Use tools for automatic secret rotation and updates. For example, integration with Vault, AWS Secrets Manager, etc.
-
Check that secrets are not cached in memory longer than necessary. Avoid storing secrets in global variables or singletons without update capability.
-
Log the secret update process and errors. This will help understand why the service does not update secrets.
Example: if the service reads a secret from a file, after updating the file, you should either send a restart signal or implement a watcher that updates the secret in memory.
