Open Challenges in Internet of Things Security

Abstract

The uses of internet of things (IoT) is increasing exponentially, number of connected devices became (according to reports) larger than human population, the uses of IoT applications involved of all aspects of our lives, and the data itself that is collected and transmitted by IoT devices and networks is very sensitive and need to be secured. All those reasons create and increase the need for improving IoT security solutions. In this paper, IoT security challenges was explored collected and categorized, for the purpose of having big picture for the situation. Number of researches during the last three years were studied to find out the still open challenges in IoT security, we also determined the different types of challenges categorization that was used by the researchers, and finally, we select a bigger sample of researches to discover the trend in IoT security challenges, and the changes happened during the last five years. The result of the analysis gives a clear idea about the importance of IoT security, it provides us of motivation for more researches in this area.
