Abstract: A facility diagnosis device includes: a process data acquirer that acquires process data indicating a state of a process executed in a plant; a production data acquirer that acquires production data indicating a production state in the plant; a state information generator that generates state information for estimating an operation state of a facility operating in the process based on the acquired process data or the acquired production data, or the process data and the production data; and a determiner that determines the operation state of the facility based on the acquired process data or the generated state information and the acquired production data.

Abstract: A control device of an integrated industrial system which is established in a plant, the control device includes a defender configured to perform a countermeasure of restricting at least a part of functions of a self-device, based on a detection result of a detector which detects a cyber-attack from at least one of inside and outside to the integrated industrial system.

Abstract: An integrated industrial system includes a safety instrumented system which is installed in a first zone, a host system which is connected to the safety instrumented system through a network, the host system being installed in a second zone which is different from the first zone, a detector which is installed in each of the first zone and the second zone, the detector being configured to detect a cyber-attack from outside to a self-zone, and a defender configured to perform a countermeasure of restricting a communication between the first zone and the second zone or of restricting a communication in the first zone or the second zone, based on a detection result of the detector.
