Publication number: 20200092313Abstract: 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.Type: ApplicationFiled: January 20, 2017Publication date: March 19, 2020Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Teruyoshi YAMAGUCHI, Tsunato NAKAI, Koichi SHIMIZU, Nobuhiro KOBAYASHI

Publication number: 20190141059Abstract: 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.Type: ApplicationFiled: June 23, 2016Publication date: May 9, 2019Applicant: Mitsubishi Electric CorporationInventors: Koichi SHIMIZU, Teruyoshi YAMAGUCHI, Tsunato NAKAI, Nobuhiro KOBAYASHI
