An Overview of the Security Challenges in IoT Environment

Abstract

The internet of things (IoT) is a huge network of heterogeneous devices; sensors and actuators, which provide a better world of services such as smart cities, smart grid, health care, smart agriculture and so on. This novel concept represents a rich area of research challenges. Instead, the most important aspects of the IoT networks are security and privacy. Because of the potential augmentation of IoT devices number and their limitations in terms of computational power, energy and memory, those aspects become more and more difficult to be established. This chapter consists of an exhaustive study about IoT applications and security in such environment. Hence, we present IoT deployment issues and the existent attacks on IoT environment considering the IoT layers. Then, we discuss the requirement of IoT security as well as the actual solutions for remediation of the compromised security, such as authentication protocols, intrusion detection systems and machine learning.
