AI Technical Summary

Technical Problem

The increasing networking and intelligence in control devices and systems have enhanced the potential threats, necessitating improved protection mechanisms to ensure the reliability of these systems against security incidents.

Method used

A controller system with a security unit that detects security incidents and transitions the control mode to a degeneration mode until the incident is canceled, ensuring the control unit operates in a limited mode to prevent normal operation until the threat is resolved, and prioritizes administrator operations for incident handling.

Benefits of technology

This approach enhances the reliability of protection against security threats by maintaining the control mode in a restricted state until incidents are resolved, preventing unintended restarts and minimizing security damage.

Abstract

A controller system (1) includes a control unit (100) configured to execute a control operation in order to control a control target, and a security unit (200) that is in charge of a security function for the controller system (1). The security unit (200) includes a detection means that detects presence or absence of an incident regarding security in the controller system (1). The control unit (100) transitions the control mode to the degeneration mode when the detection means detects the incident, and the control unit maintains the control mode in the degeneration mode until cancellation of the incident is detected by the detection means.
