AI Technical Summary

Technical Problem

Existing control devices for industrial machines face challenges in balancing security against convenience, as cyberattacks can cause significant damage when access rights to control information are not adequately restricted, particularly during critical operations.

Method used

A control device that dynamically adjusts access rights based on the operating state of the industrial machine, using a reception unit, control state acquisition, authorization definition information, and execution determination units to manage access requests and execute commands securely.

Benefits of technology

This approach effectively limits attacker access during critical operations, reducing potential damage while maintaining operational convenience by dynamically adjusting access rights based on the machine's state.

Abstract

A control device according to the present disclosure comprises: a reception unit that receives an execution request including access to control information relating to the control of an industrial machine; a control status acquisition unit that acquires control status information including information relating to the status of the control of the industrial machine; a privilege definition information acquisition unit that acquires privilege definition information including information regarding an access privilege to the control information corresponding to the control status information; an execution determination unit that determines whether or not to permit the execution of the execution request on the basis of the control status information and the privilege definition information, and generates execution information on the basis of the execution request if it is determined that the execution of the execution request is to be permitted; and an execution unit that executes the execution information.
