Test Dependencies Before They Test Your Recovery Plan
Most recovery plans describe how to restore a service. Fewer explain what happens when the systems required for recovery are also unavailable. That gap matters. A team may know how to redeploy an application, yet still depend on an identity provider, CI/CD platform, secrets manager, artifact repository, DNS service, or communication tool that is affected by the same incident. A recovery procedure is only credible when its dependencies are understood and tested. Map the recovery path Start with each critical service and trace the actions required to recover it. Do not stop at infrastructure components. Include the operational tools and decision points that enable people to act. A useful dependency review should answer: How will responders authenticate? Where are deployment artifacts stored? Can secrets be retrieved or rotated? Can DNS, traffic routing, and certificates be changed? How will responders coordinate if the primary collaboration platform is unavailable? Th...
