Abstract
A detection device that detects unauthorized communication in an on-vehicle network mounted on a vehicle includes: a monitoring unit that monitors first information that indicates a state or control related to the vehicle and that is transmitted in the on-vehicle network; a prediction unit that predicts an occurrence of second information in the on-vehicle network that indicates the state or control related to the vehicle based on the first information monitored by the monitoring unit; and a determination unit that determines, in a case where the second information is transmitted in the on-vehicle network, whether or not the transmitted second information is unauthorized, based on a result of prediction performed by the prediction unit.
