IoT is a rising field that is expected to dominate the world in the coming years. The number of devices connected to each other is expected to reach 20.4 billion by 2020 [24]. While IoT devices are becoming dominant presences in every home, office, hospital, etc., the lack of security may result in disaster. Security in IoT is very important and critical because for the IoT, the lack of security is not limited to the loss of information or personal data but may even become life-threatening. The heterogenous nature of IoT systems, which often involves devices with constrained power and computational limitations, make finding security solutions for IoT very challenging [25]. In this survey paper, we discuss IoT security from different aspects, outline IoT security requirements and measures for three-layer IoT architecture, present up-to-date security solutions, and highlight future research directions
