Thesis Abstract

Abstract
The rapid proliferation of Internet of Things (IoT) devices in various domains has raised concerns about the security of these interconnected networks. Intrusion detection is a critical component of ensuring the security and integrity of IoT systems. Traditional rule-based intrusion detection systems may not be effective in detecting sophisticated and evolving cyber threats in IoT environments. Machine Learning (ML) techniques have emerged as a promising approach for enhancing intrusion detection capabilities in IoT networks. This thesis explores the application of ML algorithms for intrusion detection in IoT networks, aiming to improve the detection accuracy and efficiency while reducing false positives.
