8. The system according to claim 1 , wherein the data comprises a state feature vector representing a state of the vehicle.
9. The system according to claim 8 , wherein the software is executable to change the state feature vector responsive to identifying an anomaly in communications over the in-vehicle communication network.
10. The system according to claim 1 , wherein the software is executable to raise an alert responsive to identifying an anomaly in communications over the in-vehicle communication network.
11. The system according to claim 1 , wherein the software is executable to identify if at least one of the messages received via the at least one communication port is anomalous.
12. The system according to 11 , wherein the monitoring data comprises data relevant to tracking performance of the module, responsive to identifying at least one anomalous message.
13. The system according to claim 12 , wherein the monitoring data comprises information regarding one or more anomalous messages identified by the module.
14. The system according to claim 12 , wherein the hub is operable to track the performance of one or more of the plurality of modules.
15. The system according to claim 14 , wherein the tracking of performance comprises determining how frequently one or more the plurality of modules generates false positives or false negatives in identifying messages as anomalous messages.
16. The system according to claim 1 wherein the module is configured to transmit the monitoring data or a portion thereof based on a request that the module receives from the hub.
17. The system according to claim 16 wherein the transmission of the monitoring data or portion thereof is subject to authenticating the request.
18. The system according to claim 17 wherein the module is configured to stop transmitting the monitoring data or portion thereof in response to a communication from the hub.
19. A system for providing security to a fleet of vehicles, the vehicles being real vehicles, the system comprising:
a plurality of modules, each module configured to monitor messages propagating in an in-vehicle network of one vehicle, which is the vehicle the module is present on, comprised in the fleet, the in-vehicle network having a bus and at least one node connected to the bus, each module comprising:
at least one communication port connectable to a portion of the in-vehicle network, 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 and messages received from the in-vehicle network, an anomaly in communications over the in-vehicle communication network; and
instruct a communication interface, configured to support communication with an entity eternal to the vehicle, to transmit monitoring data reponsive to the received messages; and
a procesor configured to execute the software in the memory; and
a data monitoring and processing hub eternal to the vehicles comprised in the fleet and operable to receive transmission of monitoring data from the plurality of modules and process data in the monitoring data to identify whether within a same specified timeframe a plurality of vehicles having messages monitored by the modules is subject to a same probability of failure of a vehicle control system or component and wherein none of the processed data is generated from a message in a communication that the hub instructed a vehicle in the fleet to initiate with a suspected source of malware that the hub identified.
