Abstract
(EN)
The present invention addresses the novel problem of protecting against threats that can arise as a result of the development of networked or intelligent control devices and control systems. This controller system includes: a control unit that executes a control operation for controlling a control target; and a security unit that is connected to the control unit and oversees manages security functions for the controller system. The security unit includes a detection means that detects whether any unauthorized intrusion into the controller system has occurred. The control unit includes a command transmission means that transmits commands for changing the behavior of the detection means of the security unit.

La présente invention aborde le nouveau problème de protection contre des menaces qui peuvent survenir suite au développement de dispositifs de commande et de systèmes de commande en réseau ou intelligents. Ce système de commande comprend : une unité de commande qui exécute une opération de commande destinée à commander une cible de commande; et une unité de sécurité qui est connectée à l'unité de commande et qui supervise des fonctions de sécurité du système de commande. L'unité de sécurité comprend un moyen de détection qui détecte si une intrusion non autorisée dans le système de commande s'est produite. L'unité de commande comprend un moyen de transmission d'instructions qui transmet des instructions destinées à modifier le comportement du moyen de détection de l'unité de sécurité.
