The reason why the internal security closed-loop defense system of the industrial Internet can form a closed-loop is inseparable from the innovation of three key links: the key technologies and systems of the first real interactive industrial Internet simulation exercise, the Industrial Internet threat trapping active protection honeynet system for advanced network attacks, and the Industrial Internet trans-regional network security joint protection platform.

As the core technology of closed-loop defense system, the key technology and system of real interactive industrial Internet simulation exercise can be described as the first in the industry. This technology greatly reduces the problem of high-threat network security incidents caused by human factors, and can effectively deal with potential network security risks. Combined with the standardized model of industrial field facilities, the system innovatively designed a closed-loop autonomous controllable simulation and rehearsal system, which ensured the security of the industrial Internet from multiple angles and reached the international leading level. At present, the technology has become an important part of a national laboratory network technology simulation platform, which serves the development of national scientific research and manufacturing industry, and also provides a new and real shooting range platform support for the ability training of industrial network information security talents in China.

The Industrial Internet threat trapping active protection honeynet system built in the closed-loop defense system for advanced network attacks effectively solves the requirements of both security and stability of industrial Internet enterprises, and realizes the need for high deterrence protection against network attacks by constructing the security protection barrier of the industrial Internet. Among them, in response to the need for a large number of honeynet data interaction needs, through the design of a number of innovative patented technologies, the data transmitted by the threat trapping and active protection system can be more secure and reliable in the form of dynamic data stream encryption transmission. At present, it has been promoted and applied, covering more than half of the key industrial enterprises in the country.

The industrial Internet cross-regional network security joint protection platform plays a role of interconnection in the closed-loop defense system. Using advanced technologies such as security baseline control and big data analysis, combined with the honey network system data set, a dynamic internal network joint prevention and control system of industrial Internet enterprises has been built, effectively protecting a large number of critical infrastructures with weak security protection capabilities in China. It facilitates the secure operation of the open industrial Internet for 5G. This innovation point provides continuous support for the construction of national information security vulnerability database and security guarantee tasks during major national events.

Fengtai Technology in the project through high quality, high standards and efficient technical capabilities, the successful integration and industrialization of the key technologies of the project, the formation of a set of whole industry chain products. In addition to a series of network security ranges and security operation platform products such as Industrial Internet simulation drill system, Industrial Internet threat trapping active protection honey net system, Industrial Internet cross-regional network security joint protection platform, etc., industrial Internet security solutions for various industries are also derived, effectively solving the problem of weak security defense faced by China’s industrial infrastructure. At the same time, it also provides opportunities for the cultivation of a large number of outstanding network security talents.

After 12 years of technical research, Fengtai Technology has cracked the “hard bone” of endogenous security closed-loop protection of the industrial Internet, but there is still a lot of work to be done in the construction of industrial security. The goal of Fengtai Technology is to provide security for China’s economic production and infrastructure operation, and promote scientific and technological innovation and industrial progress in the field of network security.

In the context of national importance and user needs, Fengtai Technology believes that the industrial Internet security road is blocked and long, the line is coming, the line is not stopping, the future can be expected.
