Tamper tune watchman

A method of determining if a vehicle's performance has been modified, the method comprising: acquiring operational data comprised in communications signals transmitted over a vehicle's in-vehicle network during operation of the vehicle; processing the operational data to determine an operational profile for the vehicle that characterizes actual operation of the vehicle; and determining based on the operational profile if the vehicle performance has undergone modification.. . ... Argus Cyber Security Ltd

System and method for anomaly detection in diagnostic sessions in an in-vehicle communication network

A method of monitoring communications propagating in an in-vehicle communications network of a vehicle, the method comprising: monitoring messages transmitted over at least a portion of the in-vehicle network; determining if the transmitted messages are indicative of a current data transfer session conducted over the in-vehicle network; comparing at least one feature of a message of the transmitted messages to at least one expected feature of a message comprised in a model of the data transfer session to determine whether or not the at least one feature of the transmitted message is expected; determining that the transmitted message is an anomalous message if the feature of the transmitted message is determined to be unexpected.. . ... Argus Cyber Security Ltd

Message data acquisition

An in-vehicle communication network comprising at least one node connected to a bus, the network comprising: at least one memory comprising software having data characterizing messages that propagate over the network during normal operation and executable instructions for processing a message based on the data to determine if the message is normal or anomalous; a module operable to: process messages received from the in-vehicle network in accordance with the executable instructions and the data to identify an anomaly in communications over the in-vehicle communication network; accumulate and store information responsive to the processing of the received messages; instruct a communication interface, configured to support communication with an entity external to the vehicle, to upload the stored information or a portion thereof to the entity external to the in-vehicle network.. . ... Argus Cyber Security Ltd

Fleet monitoring

A system for providing security to a fleet of vehicles, the system comprising: a plurality of modules, each module configured to monitor messages propagating in an in-vehicle network of a vehicle comprised in the fleet; a memory having data characterizing messages, and software executable to: identify an anomaly in communications over the in-vehicle communication network; and instruct a communication interface, configured to support communication with an entity external to the vehicle, to transmit monitoring data responsive to the messages; and a processor configured to execute the software in the memory; and a data monitoring and processing hub external to the vehicles comprised in the fleet and operable to receive transmission of monitoring data from the plurality of modules.. . ... Argus Cyber Security Ltd

Obd port access control

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 to and/or receives via the bus; 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 is operable to: processes messages received via the port responsive to the software in the memory to control passage of messages through an on-board diagnostics (obd) port between the in-vehicle network and an entity external to the vehicle.. . ... Argus Cyber Security Ltd

System and method for detection and prevention of attacks on in-vehicle networks

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.. . ... Argus Cyber Security Ltd

Common state detection

A module for providing security to a vehicle's in-vehicle communication network that is responsive to an operational state of the vehicle.. . ... Argus Cyber Security Ltd

Watchman hub

A system for providing security to an in-vehicle communication network, the system comprising: a data monitoring and processing hub external to the in-vehicle network, the in-vehicle network having a bus and at least one node connected to the bus; a module configured to monitor messages in communication traffic propagating in the in-vehicle network, the module comprising: at least one communication port via which the module receives and transmits messages; a memory having data characterizing messages that the at least one node transmits and receives during normal operation of the node, and software executable to: identify, responsive to the data characterizing messages, an anomaly in communications over the in-vehicle communication network; and instruct a communication interface, configured to support communication with the hub, to transmit monitoring data responsive to identifying the anomaly to the hub for processing; and a processor configured to execute the software in the memory.. . ... Argus Cyber Security Ltd

Context-aware firewall for in-vehicle cyber securtiy

A module for providing security to a vehicle's in-vehicle communication network that is responsive to an operational state of the vehicle.. . ... Argus Cyber Security Ltd

Bus watchman

A cyber security module for providing security to an in-vehicle communication network having a bus, at least one node connected to the bus, and at least one communications device coupled to the in-vehicle communication network configured to interface the in-vehicle network with an external communication network, the cyber security module comprising: a communication port configured to receive a message from the communication device that the communication device generates based on a message that the communication device receives from the external communication network; at least one communication port coupled to the bus; an authentication module configured to authenticate whether or not the message originated from an authorized source; and a processor configured to operate to prevent content of the message from being operated on if the authentication module determines that the source of the message received by the communication device is not from an authorized source.. . ... Argus Cyber Security Ltd

System and method for controlling access to an in-vehicle communication network

A system or method may include an in-vehicle network including an interface port for connecting an external device to the in-vehicle network; and a security unit connected to the in-vehicle network, the security unit adapted to enable an external device to communicate with the in-vehicle network, over the interface port, based on a security token received from the external device. A system or method may, based on a token, prevent an external device from at least one of: communicating with a selected set of components on in an in-vehicle network, communicating with a selected set of network segments in the in-vehicle network and performing a selected set of operations.. ... Argus Cyber Security Ltd

System and method for consistency based anomaly detection in an in-vehicle communication network

A system and method for providing security to a network may include monitoring, by a processor, traffic on a first and second network portions of an in-vehicle communication network; determining whether or not a first message detected on the first network portion is anomalous based on at least one of: an attribute of a second message detected on the second network portion and an absence of a second message from the second network portion over a predefined time period; and, if it is determined the first message is anomalous then performing at least one action.. . ...
