Emerging Security Threats, Countermeasures, Issues, and Future Aspects on the Internet of Things (IoT): A Systematic Literature Review

IoT consolidates the entire world with the PC-based framework and around the end; it brings about a more prominent way of communication for the clients. Therefore, Security of IoT devices is also a major concern which helps in protecting IoT-enabled devices for the communication purpose. With the extent of the IoT framework, major security issues of various heterogeneous devices in any sensor network are being increasing day by day. Through this paper, we explore various IoT security concerns at various layers. Because of the investigation, we will feature the most basic issues with the point of controlling future research directions. Also, we have discussed a detailed literature survey along with various threats and security aspects on each layer of IoT architecture. A comparative study has also been discussed describing various parameters of IoT protocols based on features and limitations in IoT Security illustrated by various researchers.
