Internet of Things (IoT) A Study on Security attacks and Countermeasures

Abstract

Internet of Things (IoT) applications represents a new revolution in information technology field. Researchers have predicted that by 2020, the number of digitally connected devices will exceed 50 billion. However, due to the fact that IoT applications aim to provide the ability for billions of smart devices to connect and interact to each other via the Internet, IoT security challenges are huge. IoT security has always been a major concern of discussion not only for researchers, but also for users when assessing the risks of using IoT applications. IoT applications are vulnerable to various types of attacks related to security issues. Therefore, the need to protect such applications from those attacks has been increased. Many works of researchers have been conducted to reduce or minimize the effect of security attacks on IoT environment. This research aims to explore the security requirements and limitations of IoT, then classifies security attacks based on IoT architecture layers. Finally, up-to-date IoT security solutions are proposed briefly and conclusions are made. This research gives a better understanding to future trends for researchers in IoT security.
