Background. The rapid growth of IoT devices in homes put people at risk of cyberattacks and the low power and computing capabilities in IoT devices make it difficultto design a security solution for them. One method of preventing cyber attacks isan Intrusion Detection System (IDS) that can identify incoming attacks so that anappropriate action can be taken. Previous attempts have been made using machinelearning and deep learning however these attempts have struggled at detecting newattacks.Objectives. In this work we use a convolutional neural network IoTNet designed forIoT devices to classify network attacks. In order to evaluate the use of deep learningin intrusion detection systems on IoT.Methods. The neural network was trained on the NF-UNSW-NB15-v2 datasetwhich contains 9 different types of attacks. We used a method that transformedthe network flow data into RGB images which were fed to the neural network forclassification. We compared IoTNet to a basic convolutional neural network as abaseline.Results. The results show that IoTNet did not perform better at classifying networkattacks when compared to a basic convolutional neural network. It also showed thatboth network had low precision for most classes.Conclusions. We found that IoTNet is unfit to be used as an intrusion detectionsystem in the general case and that further research must be done in order to improvethe precision of the neural network.
