    Abstract: A server includes: an obtainer that obtains items of information including an item of frame information regarding a communication frame transmitted on an in-vehicle network of each of a plurality of vehicles; and a generator that generates an integrated rule that is suitable for the items of information obtained by the obtainer and is for anomaly detection processing in the in-vehicle network of one of the vehicles; and a provider that outputs the integrated rule generated by the generator. For example, the obtainer obtains condition information indicating a condition pertaining to each of the plurality of vehicles at a time when the communication frame is transmitted on the in-vehicle network, and the generator generates the integrated rule using the items of frame information associated with the condition information.

    Abstract: An anomaly detection device is a device for detecting an anomaly in a mobile body and includes: a type determiner that determines a type of an anomaly detected; a type change determiner that determines whether or not a change has occurred between a type of an anomaly detected last time and a type of an anomaly detected this time; and an anomaly detection log transmitter that transmits an anomaly detection log related to the anomaly detected this time when the change has occurred, and does not transmit the anomaly detection log related to the anomaly detected this time when the change has not occurred.

    Abstract: A master control device is communicatively coupled to a first slave control device and a second slave control device via a first network and a second network, respectively. The master control device provides output data to the first slave control device based on input data received from the second slave control device. A monitoring apparatus which monitors an operation of the master control device stores determination data indicating a correspondence relationship between the input data and the output data, obtains the input data provided to the second network by the second slave control device and the output data provided to the first slave control device via the first network, and determines a presence or an absence of an anomaly in the operation of the master control device by determining whether the input data and the output data correspond to the determination data.
