Abstract:
In recent years, the Internet of Things(IoT) has been widely deployed in intelligent manufacturing, smart homes, and smart medical services, etc. The security concerns of the IoT systems are becoming increasingly prominent, posing an unprecedented challenge to the underlying IoT system design. Security assessment, an important means for ensuring IoT security, needs to be performed throughout the development lifecycle of IoT applications. IoT nodes face challenges such as computing power, size and power consumption. The application scenarios such as smart cities propose large-scale ubiquitous heterogeneous connections and complex cross-domain requirements. We first survey the current security assessment methods and threat management technologies that are widely used in IoT. We then analyze the security technologies of IoT from the aspects of green, intelligence and openness, and summarize the development status and existing security problems from these three dimensions. Finally, we summarize the challenges of IoT security assessment and the future research directions are pointed out.
