Optimized machine learning enabled intrusion detection 2 system for internet of medical things

Abstract

This research paper proposes an intrusion detection system that combines particle swarm optimization and AdaBoost algorithms to classify and detect malware-related records in innovative health app platforms. The research employs the NSL KDD dataset, consisting of 125,973 instances and 41 features, with data split into training (20 %) and testing (80 %) sets. A feature selection process using Particle Swarm Optimization identifies 12 relevant features for intrusion detection. The intrusion detection system effectively categorizes various attack types, including Denial of Service (DoS), User-to-root (U2R), Root-to-local (R2L), and Probe attacks. Regarding classifier performance, AdaBoost exhibits the highest recall value (0.966667), highlighting its strong intrusion detection capabilities. The experimental results demonstrate that the PSO-AdaBoost approach achieves superior accuracy, precision, and recall in intrusion detection. By integrating machine learning-based intrusion detection systems into smart health apps, healthcare providers can enhance patient care, reduce costs, and ensure the confidentiality of sensitive medical information. This research highlights the potential of ML-IDSs in strengthening the security infrastructure surrounding medical IoT devices and improving patient outcomes in the interconnected world of the Internet of Medical Things.
