Operations
in practice.

Follow connected questions about operations across the Sentinel Journal.

Operational security includes what happens when the expected path breaks. These articles cover bounded work, proportionate evidence, telemetry failure, and incident recovery. They are intended for teams that need a usable ownership model alongside technical controls. Begin with one workflow and ask who can change its policy, investigate an unexpected outcome, and safely restore normal behavior. Record missing evidence and unclear authority as concrete tasks. A runbook becomes useful when the people on call have practiced the actions and possess the permissions it assumes.
