A Comprehensive Review on the Issues Related to the Data Security of Internet of Things (IoT) Devices Shivansh Upadhyay, Shashwat Kumar, Sagnik Dutta, Ajay Kumar Srivastava, Amit Kumar Mondal and Vivek Kaundal Abstract Internet of Things or IoT is an emerging Internet-based structure of various devices that allows exchange, processing and storage of data along with various other applications. With IoT dominating the industrial domains around the world, followed by its increased implementation for completing various task. Furthermore, it is also prone to malicious attacks that show the capability of the IoT devices in terms of security and privacy of the data. Though previous research in this area may have explored and brought forth the security challenges faced by IoT but there are still some gaps remain in a few places. Therefore, it is very important to design such a framework that is having the capability to face the challenges related to security. In this paper, a comprehensive analysis of security threats faced by IoT and the possible solutions are suggested to solve the issues. We ensure to conduct proper research on the legal challenges of IoT. We believe our approach can further help others to solve the threats easily.
