TENNER: intrusion detection models for industrial networks based on ensemble learning

In the pursuit of discerning patterns within computer network attacks, the utilization of Machine Learning and Deep Learning algorithms has been prevalent for crafting detection models based on extensive network traffic datasets. Furthermore, enhancing detection efficacy is feasible by applying cluster learning techniques, wherein multiple Machine Learning models collaborate to yield detection outcomes. Nevertheless, it is imperative to discern the optimal features within the dataset for training the intrusion detection model. In the present study, we proffer a novel framework for feature selection and intrusion detection within industrial networks, employing Ensemble Learning to achieve commendable performance in terms of both high predictive accuracy and efficient learning duration. The outcomes evince that the proposed model exhibits an accuracy of 99.93%, with a mere one h and 34 min required for comprehensive training. In contrast, a model trained without the framework presented in this paper attains an accuracy of 99.94%, necessitating an extensive training period of 156 h. Notably, the detection model derived from the proposed solution demonstrates superior results in prediction time, accomplishing predictions within 0.0009 seconds, compared to the alternative model which requires 0.0076 seconds for predictions.
