A vehicle network is provided with a monitoring-purpose onboard control apparatus that detects illicit data through monitoring the data communication format predetermined in order to operate a communication protocol that is used in the vehicle network. Upon detecting illicit data whose communication format is different from the prescribed communication format, the monitoring-purpose onboard control apparatus performs a process of transmitting alarm information to onboard control apparatuses, and also performs a process of prohibiting gateways from routing the illicit data. |
