Avionics intrusion detection system and method of determining intrusion of an avionics component or system

摘要

A system for an aircraft and method of determining intrusion of an avionics component or system in an aircraft having multiple avionics components and systems communicating over an aircraft communications network monitored by a system, including monitoring, by the system, data communication over the aircraft communications network for at least some of the avionics components or system and comparing, by the system, the monitored communications for the at least some of the avionics components to corresponding operational profiles.

1. A method of determining intrusion of an avionics component or avionics system in an aircraft having multiple avionics components and avionics systems communicating over an aircraft communications network monitored by an intrusion system, the method comprising:
monitoring, by the intrusion system, data communication over the aircraft communications network for one or more of the avionics components or avionics systems; comparing, by the intrusion system, the monitored communications for at least one of the avionics components or avionics systems to a corresponding operational profile that includes acceptable interactions between multiple avionics components or avionics systems; determining an intrusion for the at least one of the avionics components or avionics systems when the comparison indicates that the at least one of the avionics components or avionics systems satisfies an intrusion profile based on data redundancy checks and trend not matching; and providing an alert of the determined intrusion.
