Abstract: An information processing device comprising: a processor; and a memory including at least one set of instructions that, when executed by the processor, causes the processor to perform operations. The operations include: obtaining incident information about an incident of a cyberattack that occurred in a vehicle; obtaining second vehicle information about a state of a second vehicle via communication with the second vehicle; determining a risk level of a vehicle function of the second vehicle based on a degree of matching between the incident information and the second vehicle information; generating a function restriction command for restricting a vehicle function of a first vehicle corresponding to the vehicle function of the second vehicle, when the risk level is higher than a first criterion, the vehicle function of the first vehicle being one among one or more vehicle functions of the first vehicle; and outputting the function restriction command.

Abstract: An electronic control unit (ECU) is provided. The ECU is connected to a first network in an onboard network system. The onboard network system includes the first network and a second network. In the first network, first-type frames are transmitted following a first communication protocol. In the second network, second-type frames are transmitted following a second communication protocol. The first-type frame includes first information serving as a base for the second-type frame to be transmitted to the second network, and second information indicating that the first-type frame includes information that is to be transmitted to the second network. The ECU includes a generator that generates the first-type frame following the first communication protocol, and a transmitter that transmits, to the first network, the first-type frame generated by the generator.

Abstract: 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.

Abstract: An IDS ECU includes: an anomalous frame detector that detects an anomalous frame; a connector communicator that transmits an anomaly-related request frame to a connector that is a transmitter of the anomalous frame, to request a response from the connector, and receives, from the connector, an anomaly-related response frame generated by the connector based on the anomaly-related request frame and indicating the transmitter; a network anomaly determiner that calculates, from the anomaly-related response frame, the number of anomalous connectors indicating the number of connectors that transmitted the anomaly-related response frame, and determines that an in-vehicle network system is: in a first anomalous state when the number is 0; and in a second anomalous state when the number is not 0; and a network anomaly handler that handles the first or second anomalous state determined by the network anomaly determiner.

Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits priority data in the first transmission buffer with priority over non-priority data in the second transmission buffer, which is a non-priority transmission buffer.

Abstract: A data analysis apparatus includes: a vehicle data communicator that obtains vehicle data indicating a vehicle status of a first vehicle; a external data communicator that obtains external data indicating external circumstances of the first vehicle from at least one of a second vehicle, which is in an area where the first vehicle is running and is different from the first vehicle, and a traffic infrastructure system; a processor; and a memory including at least one set of instructions. By executing the at least one set of instructions, the processor performs: a first determination as to whether there is an inconsistency between the vehicle status of the first vehicle indicated and the external circumstances, and outputs a result of the first determination regarding the first vehicle.

Abstract: An information apparatus controlling method is provided. An instruction button for specifying a type of a target device that includes an illumination device and a floor plan representing each room in a building are displayed. A first room in the floor plan is displayed with brightness not lower than first brightness, when selection of the instruction button is detected and when a first illumination device in the first room is in an on-state. A first room screen corresponding to the first room is displayed with brightness not lower than second brightness, when selection of the first room is detected and when the first room is displayed with brightness not lower than the first brightness. A first control command is output to network for turning off power of the first illumination device in the first room, when selection within the first room screen is detected.

Abstract: A method of controlling information apparatus is provided. Illumination devices are displayed in room units. In response to a selection of a first illumination device in a first room unit, a first room corresponding to the first room unit is displayed with first brightness not lower than second brightness of a background image when the first illumination device is in an on-state. In response to a selection of the first illumination device, the first room is displayed with third brightness lower than the second brightness when the first illumination device is in an off-state. A first control command is output to network for turning off power of the first illumination device, when the first room with the first brightness is selected. A second control command is output to network for turning on power of the first illumination device, when the first room with the third brightness is selected.
