Network intrusion detection systems (NIDSs) are one of the main tools used to defend against cyber-attacks. Deep learning has shown remarkable success in network intrusion detection. However, the effect of feature fusion has yet to be explored in how to boost the performance of the deep learning model and improve its generalisation capability in NIDS. In this paper, we propose novel deep learning architectures with different feature fusion mechanisms aimed at improving the performance of the multi-classification components of NIDS. We propose three different deep learning models, which we call early-fusion, late-fusion, and late-ensemble learning models using feature fusion with fully connected deep networks. Our feature fusion mechanisms were designed to encourage deep learning models to learn relationships between different input features more efficiently and mitigate any potential bias that may occur with a particular feature type. To assess the efficacy of our deep learning solutions and make comparisons with state-of-the-art models, we employ the widely accessible UNSW-NB15 and NSL-KDD datasets specifically designed to enhance the development and evaluation of improved NIDSs. Through quantitative analysis, we demonstrate the resilience of our proposed models in effectively addressing the challenges posed by multi-classification tasks, especially in the presence of class imbalance issues. Moreover, our late-fusion and late-ensemble models showed the best generalisation behaviour (against overfitting) with similar performance on the training and validation sets.
