Voting Classifier-based Intrusion Detection for IoT Networks
This work addresses security vulnerabilities in IoT networks, but it is incremental as it applies an existing ensemble technique to a specific domain.
The paper tackles the problem of suboptimal performance in intrusion detection for IoT networks by proposing an ensemble-based voting classifier, achieving accuracies up to 97% on specific sensors like GPS and weather sensors, outperforming traditional methods.
Internet of Things (IoT) is transforming human lives by paving the way for the management of physical devices on the edge. These interconnected IoT objects share data for remote accessibility and can be vulnerable to open attacks and illegal access. Intrusion detection methods are commonly used for the detection of such kinds of attacks but with these methods, the performance/accuracy is not optimal. This work introduces a novel intrusion detection approach based on an ensemble-based voting classifier that combines multiple traditional classifiers as a base learner and gives the vote to the predictions of the traditional classifier in order to get the final prediction. To test the effectiveness of the proposed approach, experiments are performed on a set of seven different IoT devices and tested for binary attack classification and multi-class attack classification. The results illustrate prominent accuracies on Global Positioning System (GPS) sensors and weather sensors to 96% and 97% and for other machine learning algorithms to 85% and 87%, respectively. Furthermore, comparison with other traditional machine learning methods validates the superiority of the proposed algorithm.
