Abstract

This enables millions of connected devices and smart manufacturing systems, making IIoT an integral part of Industry 4.0 environments. Nonetheless, the fast growth of IIoT infrastructures has tremendously augmented industrial network exposure to various cyber attacks like DDoS, scanning and infiltration. Existing intrusion detection systems have difficulty managing and reliability reporting of threats in scalable distributed environments. To counter these challenges, this paper presents a novel vertical hybrid intrusion detection framework assisted by the blockchain to integrate a deep learning-based model for detection with blockchains in decentralized infrastructure. This paper proposes a system that leverages the Bidirectional Long Short-Term Memory (BiLSTM) network model to learn about temporal traffic patterns in the time series for IIoT network flows. Using Blockchain technology, we secure the IDS logs for integrity and transparency of threat data shared between distributed nodes. The proposed approach is evaluated using experiments on the BOT-IoT dataset, where it achieves a 99.3% detection accuracy and surpasses many state-of-the-art models for intrusion detection. Results Demonstrate the potential improvement of IIoT intrusion detection systems with integrated blockchain and deep learning methods.
