Security Issues and Its Countermeasures in Examining the Cloud-Assisted IoT

Abstract

Internet of Things (IoT) offers the capability to connect and integrate both digital and physical objects to the internet and to enable machine-to-machine and machine-to-human communication or interactions services. The real-time adoptions and deployments of such systems for different applications such as smart cities, smart grids, smart homes, or smart environments require guaranteed security and privacy-enabled IoT services. This is due to fact that devices in the IoT generate, process, and exchange huge amounts of safety-critical data as well as privacy-sensitive information. In order to ensure secure and safe operation and to avoid cyber-attacks on such systems, it is crucial to incorporate security and privacy measures to countermeasure the different possible attacks. This chapter presents different security and privacy requirements and a taxonomy of security threats in the context of the IoT. In addition, the authors survey the most relevant defense strategies available in the literature related to IoT security with their merits and demerits.
