Abstract: A control system includes a control unit configured to control a control object and communicate with an external device, and a relay unit configured to relay access from the external device to the control unit. The relay unit includes a reception unit configured to receive an authentication request from a request source, an authentication unit configured to authenticate validity of the request source upon receipt of the authentication request by the reception unit, and an access management unit configured to control a restriction level of access from the external device to the control unit when the validity of the request source is authenticated by the authentication unit.

Abstract: A control system includes a control engine that cyclically updates internal state values on the basis of a signal exchanged with a control target; a security engine that executes an incident response operation in response to an incident that possibly occurs in the control system; and a phase update module that updates a phase value indicating an operation state of the control target on the basis of one or more values selected discretionarily in advance by a user from among the internal state values retained by the control engine. The security engine retains operation definition information in which the content of the incident response operation is defined for each phase, and executes a corresponding incident response operation defined in the operation definition information in accordance with the phase value updated by the phase update module.

Abstract: A control device that has received a request for starting the execution of a control program issues a comparison request to two control devices that store shared information, the control devices that have received the comparison request each compare unique information created by the own control device with unique information on the own control device contained in a piece of the shared information stored in each control device, and when the comparison result satisfies a prescribed condition, the execution of the control program is permitted.

Abstract: A support device is connected to a controller system that controls a control target. The controller system can execute an incident response operation of changing a behavior in accordance with an incident that may occur in the controller system. The support device includes a selection module and a setting module. The selection module receives selection of a facility type corresponding to the control target among plural facility types which is preset. The setting module reflects a response rule corresponding to the selected facility type in the controller system by referring to a response rule that is prepared in advance for each of the facility types and defines a behavior for an incident.

Abstract: A controller system according to the present invention includes: a control unit that executes control calculation for controlling a control target; a security unit that is connected to the control unit and that is in charge of security functions for a controller system; an attack pattern creation part for acquiring setting information in the controller system and creating an attack pattern for the controller system on the basis of the acquired setting information; and an attack execution part for executing an attack on the controller system according to the created attack pattern and evaluating whether or not the security functions set in the controller system are valid on the basis of the behavior of the controller system in response to the attack.

Abstract: A control system including a controller system and a support device is provided. The controller system controls a control target. The support device supports setting of the controller system. The support device includes a system-configuration input part, a threat analysis database, a threat-scenario creating part, a countermeasure database, a countermeasure creating part, and a security setting part. The countermeasure creating part creates a countermeasure scenario containing a countermeasure for each of protected assets of the controller system according to a threat scenario and countermeasures of the countermeasure database.

Abstract: A controller system is provided with a control unit, a security unit, and a presentation means (HMI). The security unit stores countermeasure scenarios corresponding to threat analyses concerning the device configuration and protected assets of the controller system, and sets security functions in accordance with the countermeasure scenarios. The presentation means presents a user with points requiring security countermeasures in the controller system in accordance with the countermeasure scenarios.

Abstract: A control device has a first sensor set with a first detection region, a second sensor set with a second detection region, and a control unit for controlling a predetermined operation based on a detection result by the first sensor and a detection result by the second sensor.

Abstract: A battery state monitoring portion intermittently monitors the low voltage battery for supplying power to electrical components arranged in a vehicle while the power supply to the low voltage system load other than a +B load is stopped, a DCDC converter is stopped, and a +B power supply mode in which the vehicle cannot travel is set. A charging control portion starts up the DCDC converter and charges the low voltage battery with the power of a high voltage battery as a power source of the vehicle through the DCDC converter when the voltage of the low voltage battery becomes lower than or equal to a charging start voltage when the +B power supply mode is set. The present invention can be applied to a charging device of a battery of an electric vehicle.
