The Current Research of IoT Security

In recent years, the development of the Internet of Things technology has been very rapid. However, with the explosive growth of IoT devices, the challenges facing the IoT environment are becoming more and more serious. How to ensure the security of the IoT becomes a key issue. The primary purpose of IoT security is to protect private data and ensure the security of IoT users, infrastructure, data and devices. This paper reviews the threat challenges and IoT security models at each level of the Internet of Things in recent years and discusses some of the past and future solutions. At first, the IoT security threats are systematically introduced from the perspectives of physics, network and data. In addition, the mainstream IoT security model is introduced. Then we introduce solutions to IoT threats from three perspectives, including IoT access control, intrusion detection and distribution methods. In the end, the paper introduces the current IoT security model has not formed a unified standard and expresses a future expectation for the development of future security model.
