IoT-Botnet Detection and Mitigation for Smart Healthcare Systems using Advanced Machine Learning Techniques

Abstract

The Internet of Things (IoT) age is quickly evolving, with millions of devices and many more intelligent systems, like healthcare. Attackers mostly aim for these IoT devices. These devices are infected with malware, which turns them into bots that are used by attackers to disrupt networks as well as steal important data. To address this issue, efficient machine learning combined with appropriate feature engineering is proposed to detect and protect the network against vulnerabilities. The proposed model will detect Distributed Denial of Service (DDOS)-based botnet attacks in the smart healthcare system. Hacktivists frequently use DDoS assaults to overwhelm networks and make them unusable. For healthcare providers who depend on network connections to enable efficient patient data access, this can be a serious problem. DDoS attacks are motivated by a social, political, ideological, or economic motive tied to a scenario that enrages cyber threat actors. Two modern Machine Learning (ML) methods, including (i) Support Vector Machine (SVM) and (ii) Light Gradient Boosting Machine (Light GBM), are used to validate the data set. From the extensive experimental analysis, feature-based algorithms are superior to other competing models in that they (i) have the highest detection rate with high accuracy, and (ii) have less computational complexity with minimal training and test time.
