One Dimensional Conv-BiLSTM Network with Attention Mechanism for IoT Intrusion Detection

In the face of escalating intricacy and heterogeneity within Internet of Things (IoT) network landscapes, the imperative for adept intrusion detection techniques has never been more pressing. This paper delineates a pioneering deep learning-based intrusion detection model: the One Dimensional Convolutional Neural Networks (1D-CNN) and Bidirectional Long Short-Term Memory (BiLSTM) Network (Conv-BiLSTM) augmented with an Attention Mechanism. The primary objective of this research is to engineer a sophisticated model proficient in discerning the nuanced patterns and temporal dependencies quintessential to IoT network traffic data, thereby facilitating the precise categorization of a myriad of intrusion types. Methodology: The proposed model amalgamates the potent attributes of 1D convolutional neural networks, bidirectional long short-term memory layers, and attention mechanisms to bolster the efficacy and resilience of IoT intrusion detection systems. A rigorous assessment was executed employing an expansive dataset that mirrors the convolutions and multifariousness characteristic of genuine IoT network settings, encompassing various network traffic paradigms and intrusion archetypes. Findings: The empirical evidence underscores the paramountcy of the One Dimensional Conv-BiLSTM Network with Attention Mechanism, which exhibits a marked superiority over conventional machine learning modalities. Notably, the model registers an exemplary AUC-ROC metric of 0.995, underscoring its precision in typifying a spectrum of intrusions within IoT infrastructures. Conclusion: The presented One Dimensional ConvBiLSTM Network armed with an Attention Mechanism stands out as a robust and trustworthy vanguard against IoT network breaches. Its prowess in discerning intricate traffic patterns and inherent temporal dependencies transcends that of traditional machine learning frameworks. The commendable diagnostic accuracy manifested in this study advocates for its tangible deployment. This investigation indubitably advances the cybersecurity domain, amplifying the fortification and robustness of IoT frameworks and heralding a new era of bolstered security across pivotal sectors such as residential, medical, and transit systems.
