A Critical Study on Security Threats, Issues, and Challenges in the Internet of Things

Abstract

Smart grid, smart homes, intelligent water networks, and smart transport are the most infrastructural structures possible today to link our planet. The general vision of such systems is usually linked to a sole notion called the internet of things (IoT). In IoT, the whole solid infrastructure is diligently linked to information and communication technology through the use of networked embedded devices, where smart surveillance and control can be done. In such a sophisticated dynamic system, all instruments are interconnected to provide useful measurement and control instructions through the distributed sensor networks. The way we interact with the world around us is fast changing in technology. We are moving to new networking paradigms, the internet of objects (loT), which maintains data generation and internet communication for greater value and service through the worldwide number of interconnected sensors or intelligent objects. The IoT should facilitate the interconnection and sharing of information and useful data through thousands of devices, people, and services. To revolutionize the way the internet works, the IoT seeks to put together the ideas of machine-to-machine connectivity, big data, artificial intelligence, etc., to operate within a shared framework to interconnect cyberspace and human beings, which contributes to the advancement of cyber-physical systems. The idea of IoT has drawn considerable attention to research as the huge connectivity presents several challenges and hurdles, such as heterogeneity, scalability, safety, large data, and power demand. To achieve a stable IoT implementation, several security concepts on each layer should be enforced. The future of IoT can only be secured by discussing and resolving the security problems associated with it. Several researchers have tried by introducing effective countermeasures to resolve the security issues for IoT layers and tools. To date, there are limited surveys that highlight the challenges and issues of the IoT that has been identified as unique to the future internet and that various research communities must address and address. This paper gives an overview of security principles, technology and security challenges, proposed counter-measures, and future directions for IoT security. So far, a limited number of surveys have highlighted the challenges and issues of the IoT, the unique feature of this future network, and which different research groups have to face and address.
