Rotate all API keys and secrets on a defined schedule

Rotating API keys and secrets on a defined, recurring schedule limits how long any single leaked credential remains useful to an attacker, since an old key that has had years to potentially leak through a log file or an old commit is closed off regularly rather than indefinitely valid.

A credential leak often goes undetected for a long time, regular rotation means even an undetected leak has a real, limited window of usefulness rather than being valid forever.

How to do it

1. 1
   Inventory every API key and secret your systems use

   Third-party integrations, internal services, anything with a real credential.
2. 2
   Set a real recurring rotation schedule

   Frequency appropriate to how sensitive each credential is.
3. 3
   Rotate systematically, confirming each replacement works

   Update the credential everywhere it is used, and verify functionality before considering the rotation complete.
4. 4
   Document the rotation process

   So future rotations are straightforward rather than a rediscovery each time.
