Abstract

A vehicle system, comprising multiple electronic control units (ECUs) configured to manage operation of multiple vehicle components, a controller area network (CAN) bus that provides communication pathways between the multiple ECUs, and a threat validation module configured to receive a message from an electronic control unit (ECU) of the multiple ECUs, wherein the message comprises data of a suspicious message flagged by the ECU, generate a query to determine authenticity of the message, broadcast the query to at least one ECU of the multiple ECUs, listen for responses from the at least one ECU, and determine whether the suspicious message is an actual threat based at least on a count of received responses.
