Abstract

Internet of Things (IoT) has drawn significant attention in recent years since it has made revolutionary changes in human life. The IoT enables the exchange of information in a wide variety of applications such as smart buildings, smart health, smart transport, and so on. These diverse application domains can be unified into a single entity referred as smart life. The rapid evolution of the IoT has pushed a race between cyber-criminals and security experts. As billions of connected things communicate with each other and can exchange sensitive information that may be leaked. Hence, strengthening IoT’s security and preserving users’ privacy is a major challenge. This paper aims to provide a comprehensive study of the IoT security. Several IoT security attacks are analyzed, and a taxonomy of the security requirements based on the attacks’ purposes is proposed. Moreover, recent security solutions are described and classified based on their application domains. Finally, open research directions and security challenges are discussed.
