Patent ID: 10868817

Abstract:
A data processing system that provides for active prevention of masquerading attacks comprises a microcontroller, a transceiver, and an active attack prevention module (AAPM) in communication with the microcontroller and the transceiver. The microcontroller enables the data processing system to operate as a node in a vehicle control system (VCS). The transceiver enables the node to communicate with a local area network (LAN) of the VCS. The AAPM enables the node to monitor the LAN for messages. In response to detecting a message on the LAN, the AAPM automatically determines whether the message falsely identifies the node as a source, based on a value in an identifier field in the message. In response to determining that the message falsely identifies the node as the source, the AAPM automatically takes at least one remedial action to neutralize the message. Other embodiments are described and claimed.
