(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION D'UN LOGICIEL ANORMAL SUR UN CONTRÔLEUR LOGIQUE PROGRAMMABLE
Abstract: front page image
(EN)There is provided a method including: during a training period, collecting a plurality of scan cycle times of a programmable logic controller (PLC) program executing on a PLC; calculating one or more baseline parameters based on the plurality of scan cycle times; determining a baseline PLC program signature based on the one or more baseline statistical parameters; and storing the baseline PLC program signature.
(FR)L'invention concerne un procédé consistant à : pendant une période d'apprentissage, collecter une pluralité de temps de cycle de balayage d'un programme de contrôleur logique programmable (PLC) s'exécutant sur un PLC; calculer un ou plusieurs paramètres de base d'après la pluralité de temps de cycle de balayage; déterminer une signature de programme PLC de base d'après le ou les paramètres statistiques de base; et stocker la signature du programme PLC de base.
