Security threats in IoT

The Internet of Things (IoT) is a massive group of devices connected over wired or wireless networks. IoT aims to provide advanced and intelligent services but at the same time to ensure security. It is a challenge to find lightweight security models and techniques as the IoT devices have low resources and low computing power. As a result, IoT devices became a target of cyber-attacks because of deficiency in safety mechanism. This paper discusses the vulnerabilities of IoT devices and several security challenges. It contains some detailed implementation and analysis of IoT oriented attacks and some security solutions.
