With the deepening integration of the new generation of information technology and manufacturing industry，the industrial Internet has become the key support for the new industrial revolution，and industrial Internet security has also become an important prerequisite and guarantee for building a powerful nation on both manufacturing and internet. In recent years，the developed countries such as the US and Germany have carried out many initiatives simultaneously，to guarantee the industrial Internet security from the aspects of formulating strategic standards，enhancing technical abilities and promoting industry development. China attaches great importance to the safety of industrial Internet，in November of 2017，the State Council issued “Guidance to Deepen the Development of Industrial Internet of‘Internet plus Advance Manufacturing Industry’”，the guidance clearly suggests that security is one of the three major functional systems of the industrial Internet，and requires that we should adhere to the industrial Internet security means，including synchronous planning，synchronous construction and synchronous operation，and accelerate the establishment of a security system for the reliable industrial Internet.
