Recover treatment-system keys during a flood or facility loss
Can an alternate control location authenticate and decrypt essential systems when the primary site is inaccessible?
Operational pain
Backups may exist but depend on the same facility, directory, network, or key service affected by the disaster.
Trigger
Flood exercise, resilience grant, new alternate control room, or recovery audit.
QNSI contribution
Connect the decision to a controlled security path
Use QNSI dependency and key-ownership records to identify recovery prerequisites, offline material, roles, and expiry.
Decision artifact
A treatment continuity exercise report showing recovered functions, missing dependencies, custody events, and corrective work.
What still requires validation
The utility proves secure storage, dual authorization, restoration order, process safety, post-recovery rotation, and reconciliation.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
