  • Publication number: 20200314130
    Abstract: In an attack detection device, a white list storage unit correlates and stores, for each system state, a white list defining system information permitted in the system state. A state estimation unit estimates a current system state of a control system on the basis of communication data communicated between a server device and equipment. An attack determination unit acquires the white list corresponding to the current system state from the white list storage unit, and determines whether or not an attack has been detected, on the basis of the acquired white list and the system information in the current system state.

  • Publication number: 20200092313
    Abstract: An allowed communication list conversion unit (123) assigns one or more flags to request communication and response communication, between which a correspondence relationship is described in a detection rule, and describes, in an allowed communication list, details of a flag operation specifying a value to be set to the flag and a flag condition for determining whether the value to be set is set in the flag, in association with each other. A determination unit (103) sets the value after determining that communication data on the request communication is normal, determines whether the value is set in the flag based on the flag condition when determining whether communication data on the response communication to the request communication is normal, and determines that the communication data on the response communication is normal when the value is set, to thereby reset the flag.

  • Publication number: 20190141059
    Abstract: A state management unit (210) identifies a state of an operational system, and determines presence or absence of a state transition of the operational system based on the identified state. In a case where there has been a state transition of the operational system, the state management unit determines, with use of a state transition scenario indicating a transition pattern of state transition, whether the state transition of the operational system matches the transition pattern indicated in the state transition scenario. If the state transition of the operational system does not match the transition pattern, an alert output unit (293) outputs an alert. If the state transition of the operational system matches the transition pattern, a whitelist management unit (220) switches whitelists, and an intrusion detection unit (230) performs whitelist-type intrusion detection.
