An Effective Deep Learning-Based Intrusion Detection System for the Healthcare Environment

In the medical field, Internet of Things (IoT) applications allow for real-time diagnosis and remote patient monitoring, commonly called Internet of Health Things (IoHT). However, cybersecurity attacks may interrupt hospital operations and threaten patients’ health and well-being due to this integration. Hence, developing an Intrusion Detection System (IDS) suited explicitly for healthcare systems is essential to ensure efficiency and accuracy. Nevertheless, it is challenging to integrate anomaly-based IDS frameworks in healthcare systems as they necessitate additional processing time, temporal feature retention, and increased complexity. Therefore, a deep learning system based on SqueezeNet and NasNet is presented in this paper to detect intrusions in a healthcare setting. In this, SqueezeNet is employed to extract more significant features. On the other hand, network breaches while data transmission across distinct locations are detected by the NasNet-based classifier. In addition, the Rider Optimization Algorithm (ROA) is applied to adjust the classifier’s hyperparameters, guaranteeing that it would accurately detect attacks. Moreover, the Auxiliary Classifier Generative Adversarial Network (ACGAN) approach is integrated into the proposed framework to avoid data imbalance. Applying different performance constraints, the proposed approach is thoroughly assessed on three publicly available datasets (TON-IoT, ECU-IoHT, and WUSTL-EHMS). The results show that the proposed deep learning-based cybersecurity model outperforms traditional methods and produces better outcomes.
