INFRDET: IoT network flow regulariser-based detection and classification of IoT botnet

Internet of Things (IoT) botnet is one of the attacks which affect the working of authentic IoT devices. In this paper, a novel light-weighted intelligent system has been devised by using traffic analysis and regulators to detect botnet-infected devices in the IoT network. The system operates on a low-powered Raspberry Pi device with network packet counts. Besides, an IoT Network Flow Regulariser (INFR) algorithm is proposed and embedded for transforming network flows to the uniform length traffic frame. The experimental results show the better performance of the proposed system with the INFR algorithm in comparison to the existing work. In addition, to classify the benign and malicious traffic, a novel method is used to visualise the network activities through graphical heatmaps. These heatmaps are further investigated using a hybrid Convolution Neural Network (CNN) model without and with the INFR algorithm and therefore receive remarkable differences in terms of better results.
