Abstract: A vehicle system is a vehicle system used for a vehicle, and includes: a plurality of in-vehicle apparatuses installed in the vehicle; and at least one of (i) a controller that, in accordance with a depth of penetration of a malicious attack carried out on the plurality of in-vehicle apparatuses, changes at least one of a communication method with an outside of the vehicle, a defense method against the malicious attack, or a storage method for logs pertaining to the plurality of in-vehicle apparatuses, or (ii) a determiner that determines whether or not the malicious attack is being carried out based on anomaly detection in the plurality of in-vehicle apparatuses.

Abstract: An information processing device includes a guest OS and a host OS that accesses a sector group in response to an access request from the guest OS. The host OS includes: an access log analyzer that generates, by reference to a sector-group database, a sector-group access log from the access request; a sector-group access determiner that determines, based on the sector-group access log, whether the access request seeks to access the sector group related to an application; and a manager that updates, based on a developer definition policy, a sector-group access rule database and the sector-group database if it is determined that the access request seeks to access the sector group and the guest OS makes a change to an application storage area.

Abstract: A monitoring apparatus includes a storage unit, a reception unit, a collation information generation unit, and a response unit. The storage unit stores a criterion for determining normality of a frame transmitted from a first electronic device. The reception unit receives the frame from a bus network. The collation information generation unit generates, when the reception unit receives a frame of a first identifier (ID) transmitted from the first electronic device, collation information which is information for collation with the criterion stored in the storage unit, based on the frame. The response unit transmits, when the reception unit receives a frame of a second ID transmitted from the second electronic device, information which is based on the criterion stored in the storage unit and the collation information generated by the collation information generation unit and which enables a check whether the first electronic device is valid, to the second electronic device.

Abstract: An analysis ECU acquires information related to a first flow and information related to a second flow, the first flow and the second flow organizing packets transferred in a monitored system into respective groups. The analysis ECU acquires information related to a conversion that takes the first flow as input and the second flow as output. The analysis ECU acknowledges alert information generated in the monitored system and including information capable of identifying at least one flow. The analysis ECU generates, when the second flow is identified by the alert information, route information that includes at least one of the information related to the conversion and the information related to the first flow associated with the second flow in the information related to the conversion.

Abstract: An information processing apparatus includes: a communication device that communicates with an external apparatus outside the information processing apparatus; a memory that includes a protected region and an unprotected region; a processor that operates in a first mode and a second mode, the first mode being a mode in which access to the protected region and access to the unprotected region are allowed, the second mode being a mode in which access to the protected region is prohibited and access to the unprotected region is allowed; a first device controller that controls the communication device by the processor operating in the first mode; a virtual machine manager that causes one or more virtual machines to operate by the processor operating in the second mode; and a second device controller that controls the communication device by the processor operating in the second mode.

Abstract: An information processing device includes: a storage that stores determination criterion information indicating a determination criterion for determining whether or not a behavior of an application operating on a device provided to a vehicle is normal; and a detector that obtains behavior information indicating the behavior of the application, and detects an anomaly in the behavior of the application, based on (i) state information that indicates a state of the mobility and is obtained via the mobility network and (ii) the behavior information obtained and the determination criterion information stored in the storage.
