Title:
SYSTEMS, METHODS, AND DEVICES FOR DETECTING ANOMALIES IN AN INDUSTRIAL CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/104691
Kind Code:
A3
Abstract:
A method of detecting anomalies in an industrial control system includes analyzing data of correct operational parameters from at least one input device and storing the correct operational parameter or a correlation of at least two operational parameters as training data. The training data is used to train an anomaly detection system. Current operational parameters of the at least one input device are detected. The anomaly detection system then checks at least one of the detected operational parameter or a correlation of at least two detected operational parameters to detect a deviation from the training data. When the detected deviation is above or below a defined threshold, a communication function is performed. For example, the communication function is at least one of creating an alarm, communicating data to at least one of a control system and an operator, and recording the data or the alarm.
