Abstract: With the continuous development of the Internet of things technology, the IoT market has been presenting an exponential growth trend , the number of IoT device is increasing rapidly. In the meantime, security incidents in the IoT show an explosive growth and the security environment continues to deteriorate. Many countries have begun to strengthen the security of the Internet of things from strategic, standard, regulatory and other areas of high concern. Nowadays The capability of the Internet of things in information security protection is unevenly distributed, showing the tendency of “platform weight, terminal light”. Due to the large number of IoT smart device ,the limited computing capacity and technical capacity, the IoT smart device has become the weak link of IoT security. This paper analyzes the security threats of IoT device and propose targeted responses.
