An attack analysis device includes: an obtainer that obtains in-vehicle network information indicating a configuration of an in-vehicle network including a plurality of external communication interfaces and a plurality of control Electronic Control Units (ECUs), and anomaly detection information indicating a result of detecting an anomaly in at least one node in the in-vehicle network; an attack path estimator that, based on the in-vehicle network information and the anomaly detection information, estimates an attack path in an attack on the in-vehicle network, the attack path including an entry point indicating an external communication interface that is a point of intrusion into the in-vehicle network in the attack and an attack target indicating a control ECU that is a target of the attack; and an outputter that outputs the attack path.

Attack analysis device, attack analysis method, and non-transitory computer-readable recording medium

An anomaly detection device includes: an obtainer that obtains vehicle information related to the status of a vehicle and including location data indicating the location of the vehicle; a model storage that stores, for each of a plurality of cells of a grid imposed on a map, an evaluation model for evaluating the vehicle information of the vehicle located at the cell; and a determiner that calculates, based on the vehicle information and evaluation models each being the evaluation model and corresponding to evaluation cells including a first cell including the location of the vehicle indicated in the location data and one or more second cells each having a predetermined positional relationship with the first cell, an anomaly level indicating a degree of anomaly of the vehicle information, determines, based on the anomaly level, whether the vehicle information is anomalous, and outputs a determination result.

Anomaly detection device, anomaly detection method, and recording medium

A threat information analysis server includes: an update manager that manages update information indicating that function addition to an IoT device is performed; a threat information manager that stores threat information of a cyberattack; a risk level manager that manages risk level information defining a risk level of the IoT device; a related threat information manager that manages the threat information and related threat information associating the IoT device with the risk level; a risk level updater that associates the threat information and the risk level of the IoT device with each other and updates the related threat information, based on the update information; and an outputter that outputs the related threat information managed by the related threat information manager.

Threat analysis apparatus, threat analysis method, and recording medium

An information processing apparatus connected to one or more vehicles and a threat information server storing pieces of threat information. The information processing apparatus includes: a processor; and a memory including at least one set of instructions that, when executed by the processor, causes the processor to perform: obtaining a detection result of an attack on one of the vehicles; (a) determining whether the attack is included in any one of the pieces of threat information; (b) when the attack is included therein, determining whether the resolution state to the attack included in the one of the pieces of threat information indicates that the attack has not been resolved or has been resolved; (c) deciding a processing priority level of the attack, based on a determination result in (a) and a determination result in (b); and (d) outputting the processing priority level decided.
