摘要:
Systems and methods for detection of attacks on a communication authentication layer of an in-vehicle network, including determining, by at least one network node, at least one attack attempt on the communication authentication layer of the in-vehicle network, wherein the determination is carried out by identifying anomalies in at least one of messages, data and metadata directed to the communication authentication layer, and selecting, by the at least one network node, a response corresponding to the determined attack attempt from at least one of modification of parameter values corresponding to a security protocol, a failsafe response, and rejection of messages identified as anomalies.

摘要:
A system and method securing an in-vehicle network in a vehicle may include a switch connected to at least two segments of the in-vehicle network and an IDPS connected to the switch. The IDPS unit may be adapted to: receive network messages from the switch; determine at least some of the network messages are related to a cyber threat and configure the switch according to the cyber threat. The IDPS unit may be included in the switch.
摘要:
A module for providing security to an in-vehicle communication network having a bus and at least one node connected to the bus, the module comprising: a memory having software comprising data characterizing messages that the at least one node transmits and receives via the bus during normal operation of the node; a communication port via which the module receives and transmits messages configured to be connected to a portion of the in-vehicle network; and a processor that processes messages received via the port from the portion of the in-vehicle network responsive to the software in the memory to: identify an anomalous message in the received messages indicative of exposure of the in-vehicle network to damage from a cyber attack; and cause the module to transmit at least one signal via the port to the portion of the in-vehicle network that alters the anomalous message so that the at least one node will discard it.
