Abstract
Described herein are various technologies for detection and mitigation of rogue terminal attacks on multiplex data buses. An intrusion detection device is incorporated between a bus controller and a bus of a multiplex data bus. The intrusion detection device receives message that are communicated among the bus controller and a plurality of remote terminals (by way of the bus). The intrusion detection device determines whether messages are unauthorized based upon origins of the messages and predefined rules. When a message is determined to be unauthorized, the intrusion detection device outputs a notification that the unauthorized message has been detected and can block the unauthorized message.
