Control PhysicalChecks

A physical host device, that could therefore be physically as well as electronically attacked (unlike a VirtualHost).

Device Gateway is physically monitored to rapidly detect if it has been physically removed, altered or substituted, so its manager HostManager can address any physical compromise. This strategy represents a contingency plan included in the system operating policies and practices, e.g. to repair or replace the affected device. Activation of the plan restores normal service, but if the device was stolen the attacker still has possession of the original which could still be misused.

Device Gateway having found to be physically removed, altered or substituted, action has been taken by its manager HostManager to restore normal service. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. To implement the plan at runtime, signal HostManager that the problem was detected with Gateway which may need repair or replacement.
