Ufulu Lawrence Chiona, Rajendra Kumar, Gunjan Aggarwal · 2024
This paper provides an in-depth review of Intrusion Detection Systems (IDS) in the context of the Internet of Things (IoT) environment focusing on the rising significance of cybersecurity in interconnected gadgets. With the growth of IoT across industries there are complex security threats to overcome due to the diverse range of devices and their extensive connections leaving these networks susceptible to cyber risks. The paper discusses concepts like active intrusions outlining how IDS functions encompass network-based (NIDS) and host-based (HIDS) systems, as well as employing signature-based detection and behavioral analytics. It also focuses on the advancements in IDS approaches particularly focusing on the shift towards advanced machine learning algorithms that can adapt to the evolving threats within IoT. Furthermore, it explores studies in this field covering strategies from countering Denial of Service attacks to developing intrusion prevention mechanisms. The findings suggest a necessity for creating a stochastic model using machine learning techniques to effectively counter threats and enhance performance.
