Drill Webhook Signature-Key Rotation

Key takeaways

  • Keep event authenticity evidence tied to exact versions and identities.
  • Exercise permitted, denied, failure, and recovery cases.
  • Leave production authority and risk acceptance with named owners.

Scope the exact boundary

Drill Webhook Signature-Key Rotation stage 1 addresses event authenticity for the bounded objective to accept an overlap window without making stale keys permanent or dropping queued events. Record the repository, commit, dependency or protocol revision, environment, actor, timestamp, input fixture, expected state, observed state, and durable evidence identifier. The offshore developer may prepare instrumentation, synthetic fixtures, test code, comparison tables, and a reversible patch; the service and security owners retain authority for production access, exceptions, rollout, and risk acceptance. This stage is deliberately specific to webhook-signature-key-rotation-drill, so a passing result cannot be generalized to a different proxy, client, provider, configuration, or release.

Drill Webhook Signature-Key Rotation evidence at stage 1 must include one permitted case, one denied or malformed case, and one recovery case. Preserve raw output before normalization, identify clock and sampling limits, and distinguish an absent signal from a successful control. If evidence conflicts, stop the change and route the exact discrepancy to the named owner rather than rewriting the test or weakening acceptance criteria. A backup reviewer should reproduce this event authenticity conclusion using only the retained commands, fixtures, versions, and links.

Drill Webhook Signature-Key Rotation closes stage 1 only when the expected transition and rollback boundary are explicit. Capture before-and-after state, affected scope, monitoring window, cleanup owner, and residual uncertainty. Never copy secrets, production customer data, bearer tokens, or private keys into the packet; use approved references and masked identifiers. The final claim remains narrow: the tested event authenticity behavior matched the declared expectation for the recorded versions and conditions.

Freeze identities and versions
