Abstract: When a hash expected value, which is an expected value of a hash value of activation software, is stored in a storing unit (111), a security calculation unit (110) compares the hash value of the activation software with the hash expected value. A main calculation unit (109) activates the activation software when the hash value and the hash expected value match, and stops a process when both do not match. The main calculation unit (109) performs signature verification for the activation software when the hash expected value is not stored in the storing unit (111), and stores in the storing unit (111) as the hash value expected value, the hash value of the activation software as well as activates the activation software when the signature verification is successful. The main calculation unit (109) stops a process when the signature verification is not successful.

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.

Abstract: When a hash expected value, which is an expected value of a hash value of activation software, is stored in a storing unit (111), a security calculation unit (110) compares the hash value of the activation software with the hash expected value. A main calculation unit (109) activates the activation software when the hash value and the hash expected value match, and stops a process when both do not match. The main calculation unit (109) performs signature verification for the activation software when the hash expected value is not stored in the storing unit (111), and stores in the storing unit (111) as the hash value expected value, the hash value of the activation software as well as activates the activation software when the signature verification is successful. The main calculation unit (109) stops a process when the signature verification is not successful.

A gateway device has: a monitored data acquisition unit for saving in a monitored data storage unit, as monitored data, packet data that is outputted from a mirror port of a switch, the packet data being outputted from a device being monitored; an unauthorized access detection unit for detecting unauthorized access by determining whether the monitored data is abnormal on the basis of a comparison between the monitored data and assessment rules; and an unauthorized access notification unit for notifying a server of a monitoring center, which is connected to an external network via an external communication unit, that unauthorized access has been detected.

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.
