Internet-of-Things Data Security: Challenges, Countermeasures and Opportunities
Farag Azzedin, Ibraheem Al-Hejri · 2023
Internet of Things (IoT) has introduced a revolutionary paradigm that unleashes multitude of functionalities and possibilities. Currently, IoT and its extensive range of applications have become the focal point of numerous research endeavors. While the inherent characteristics of IoT make it highly adaptable to real-world scenarios, they also expose it to potential cybersecurity risks. IoT has experienced an unprecedented number of cyberattacks, which not only affect businesses but also pose potential risks to human lives. Therefore, it is crucial to establish a comprehensive classification of IoT challenges and identify the available countermeasures. In this paper, we conduct an extensive survey on IoT security challenges and countermeasures, and propose a taxonomy to categorize them based on the three data states. Furthermore, we discuss future directions towards IoT data security.
