    Abstract: An anomaly detection device (IDS ECU) includes a detection rule generator that monitors a communication establishment frame flowing over Ethernet in a communication establishment phase of service-oriented communication and that generates, for each communication ID, a detection rule including the communication ID written in the communication establishment frame and a server (or client) address written in the communication establishment frame; an anomaly detector that monitors a communication frame flowing over the Ethernet in a communication phase of the service-oriented communication and that, by referring to a detection rule that includes a communication ID written in the communication frame, detects the communication frame as an anomalous frame when a server (or client) address written in the communication frame differs from a server (or client) address included in the detection rule; and an anomaly notifier that provides a notification of an anomaly in response to the anomalous frame being detected.

    Abstract: An intrusion point identification device includes: a threat information collector that collects and stores threat information including identification information identifying a moving body, route information indicating a route through which the threat has intruded into the moving body, and discovery information indicating a discovery date of an attack; a vehicle log collector that collects logs, extracts, from the logs, histories of points that indicate locations of one or more moving bodies within a predetermined period, and stores the histories of the points as history information, the logs indicating points that indicate locations of the one or more moving bodies, the predetermined period being set based on the discovery information; an intrusion point identification unit that identifies an intrusion point of the threat from a first attack source through a first route among the points indicated in the history information; and an intrusion point notifier that outputs the intrusion point.

    Abstract: A vehicle anomaly detection server includes: a communicator that communicates with a vehicle to receive a log of an in-vehicle network in the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: selecting, when information indicating that an anomaly is occurring to a first vehicle among vehicles is obtained by the processor, an anomaly-related vehicle from among the vehicles based on the anomaly, the first vehicle being the vehicle that communicates with the communicator; transmitting, to the anomaly-related vehicle via the communicator, a first request to transmit a log of an in-vehicle network in the anomaly-related vehicle; and determining whether an anomaly is occurring to the anomaly-related vehicle, based on information indicated by the log transmitted from the anomaly-related vehicle and received by the communicator.
