Internet of Things Security: Threats, Recent Trends, and Mitigation Approaches

The Internet of Things (IoT) is regarded as the driving force behind the Fourth Industrial Revolution. The convergence of IoT, cloud computing, and smart environments can help ensure people’s well-being. One major problem for IoT networks is protecting privacy and overcoming security threats. This paper discusses security threats across IoT networks, which can lead the researchers to develop and implement industry-wide security standards and certifications. In addition, this paper emphasizes the importance of data protection and discusses the security measures and mitigation approaches to secure personal and sensitive information, as well as other security threats within such environments. As well, the primary objective of this work is to present a contemporary review of the prevailing research areas concerning IoT security, which highlights the recent trends in IoT security, identifies inadequacies in the investigated research publications, and discusses the associated difficulties. That will assist researchers in developing an efficient, scalable, resilient, and precise intrusion detection system for IoT devices to counter large-scale attacks.
