| 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. |
