    Abstract: An anomaly monitoring apparatus in a remote operation system for remotely operating a mobility entity includes: a log collector that collects an operation log from an operation apparatus which remotely operates the mobility entity and a control log from a control apparatus installed in the mobility entity; an anomaly detector that detects whether an anomaly is present in the mobility entity based on at least one of the operation log or the control log; an attack origin identifier that, when the anomaly detector detects an anomaly, identifies an attack origin that caused the anomaly in the mobility entity from among a plurality of attack origins based on a result of comparing the operation log with the control log; and an anomaly notifier that makes a notification for taking a countermeasure for the attack origin identified by the attack origin identifier.

    Abstract: A fraud detecting method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting whether a state of a vehicle satisfies a first condition or a second condition, and switching, upon detecting that the state of the vehicle satisfies the first condition or the second condition, an operation mode of a fraud-sensing electronic control unit connected to the network between a first mode in which a first type of detecting process for detecting a fraudulent message in the network is performed and a second mode in which the first type of detecting process is not performed. Moreover, in the second mode, a second type of detecting process having a different degree to which a fraudulent message is detectible than the first type of detecting process is performed.

    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.

    Abstract: An anomaly detecting device includes a flow collector that collects an amount of flow communication traffic in each of two or more networks in an in-vehicle network system that including the two or more networks, the amount of flow communication traffic being information obtained by tallying an amount of communication traffic of one or more frames classified according to a predetermined rule that is based on header information of a network protocol; and an anomaly detector that calculates, based on the amount of flow communication traffic, an observed ratio indicating a ratio of respective amounts of communication traffic in the two or more networks and determines whether the two or more networks are anomalous based on the observed ratio calculated and a normal ratio indicating a ratio of respective amounts of communication traffic in the two or more networks in a normal state.
