Error reporting and error handling play a central role in the engineering and operation of survivable systems. Survivability is an emergent property of a system as a whole \[[Fisher 99|AA. C References#Fisher 99]\] and depends on the behavior of all of the system's components and the interactions among them. From the viewpoint of error handling, every system component, down to the smallest routine, can be considered to be a sensor capable of reporting on some aspect of the health of the system. Any error (i.e., anomaly) ignored, or improperly handled, couldcan threaten delivery of essential system services and as a result put at risk the organizational or business mission that the system supports. |
