Big data can be used to calculate the traffic flow of a city with a population of 10 million at night peak, and provide non congested routes for people about to travel; Mobile app can push users' favorite information according to their habits... In the 21st century, the wide application of big data is not only closely related to everyone's life, but also directly related to the operation efficiency of the city and the governance ability and level of the country. Du Guangda, deputy director of the network security administration of the Ministry of industry and information technology, said at this year's China international big data industry expo (hereinafter referred to as the "digital Expo") that Comprehensively Strengthening the construction of data security governance system and governance capacity is particularly important to ensure the safe and orderly flow of data, stimulate the potential value of data, and promote the high-quality development of national economy and society. He stressed that data security has become an important part of the overall concept of national security. We must accurately grasp the significance of data security in maintaining national security and promoting the development of economic and social digital transformation under the new situation, deeply understand the importance and urgency of strengthening data security, promote work in the spirit of time waits for no man, and effectively enhance the security ability to prevent and deal with data risks. Since last year, the CPC Central Committee and the State Council have made a series of deployment arrangements to strengthen data security. The data security law and the personal information protection law have been promulgated and implemented. Data security has also become a key area of deployment in the 14th five year plan and has been written into the government work report for two consecutive years. Du Guangda said that the state has established a data security coordination mechanism. As the competent department in charge of data security in the industrial and Telecommunications fields and the national leading department in promoting the development of the data security industry, the Ministry of industry and information technology resolutely implements the decisions and arrangements of the CPC Central Committee and the State Council on data security work, adheres to overall development and security, and follows the working idea of "systematization, focus and step-by-step", Focusing on the establishment and improvement of data security management systems, mechanisms and technical means, and relying on the cultivation and building of data security industry supply capacity and ecological system, we will continue to improve the data security governance system and governance capacity, and promote a good start in data security work. Problem oriented solution to industrial development problems Data security itself is not a new term, but many changes have taken place in its connotation and scope. In the face of the changing data security industry, the institutional system, technical system, industrial ecology and supply level are all in the construction stage. It is urgent to find out the key issues of industrial development. Lei Nan, director of the data security division of the network security administration of the Ministry of industry and information technology, said at the digital fair that the Ministry of industry and information technology, as the competent department of the industry, will systematically improve the supply capacity of the data security industry in combination with the data security protection needs of various industries and fields. Entrusted by the network security administration of the Ministry of industry and information technology, China Electronic Information Industry Development Research Institute (hereinafter referred to as "CCID Research Institute") and China Software Evaluation Center have conducted a series of research on how to promote the development of China's data security industry, investigating and visiting more than 60 data security supply side and demand side enterprises. Liuwenqiang, Secretary of the Party committee and vice president of CCID Research Institute, introduced that "at present, there is still a fuzzy zone in the understanding of the connotation and scope of the data security industry by industrial subjects, and there are various problems in terms of industrial supply level, demand level, ecological structure, talent reserve, etc." In the digital era, the amount of information that can be mined behind the data is increasing day by day. In the future, the capacity of China's data security market will have a huge growth space. Data security service institutions must also grow rapidly with the changes of the times to fill the market gap. At the same time, the data security product system is currently in a period of rapid development, giving birth to a variety of products with different functions. Liuwenqiang analyzed that in terms of industrial supply level, the homogeneity of technical products is serious, and the industrial technical product system is not perfect. In terms of industrial ecological structure, there is a lack of long-term coordination mechanism, and the development path and mode of supply side enterprises are not clear. To further promote the vigorous and sustainable development of the data security industry, on the one hand, we should comprehensively promote the construction of the data security industry innovation system, accelerate the construction of the national data security industrial park, and gradually establish a development pattern of multi-point layout, point to area and nationwide radiation; On the other hand, local governments should be encouraged to build a high-end and featured data security industry cluster with international influence, led by leading enterprises, by combining the industrial foundation and advantages and focusing on the application of key technology products and key fields. In addition, we should strengthen the evaluation of industrial innovation and application of data security products, services and construction, and guide the formation of a benign market competition environment oriented by technical strength and service capability. Poised for a new chapter in the common spectrum data security industry Data has become the core productivity driving the development of the global digital economy and a new highland for the game between big countries. The development of China's data security industry as a whole is in the starting stage, which needs to be promoted from the top-level design and strategic level. Lei Nan said that in terms of top-level design, the Ministry of industry and information technology is promoting the formulation of relevant policy documents on data security and industrial development, and strengthening organizational leadership and policy support. In terms of subject cultivation, the gradient cultivation mode will be adopted to vigorously cultivate three types of market subjects, namely, leading enterprises, backbone enterprises and small and medium-sized enterprises. It is planned that by 2025, the data security backbone enterprise team will have ecological leadership, and will also hold conferences, exhibitions, competitions, training, salons and other industrial activities. China's data security industry has begun to take shape, its innovation ability has been continuously enhanced, and its product system has been gradually established, which requires a higher level of public services. China Software Evaluation Center released the public service platform for the data security industry at the digital Expo. An Hui, deputy chief engineer of CCID Research Institute, said, "the public service platform for the data security industry will become a communication bridge between the government and enterprises, and between enterprises. It will jointly promote the innovative development of China's data security industry and the creation of an industrial ecology with industry enterprises, scientific research institutions, well-known experts, etc." To improve the comprehensive strength and competitiveness of the data security industry, it is necessary to rely on the strength of experts. At the digital Expo, the data security industry expert committee of the data security professional committee of the China Computer Industry Association (hereinafter referred to as the expert committee) was announced to be established to give full play to the role of think tanks and ensure the construction of Digital China and the development of digital economy. The expert committee is chaired by academician zhengjianhua of the Chinese Academy of Sciences, and six vice chairmen, including liuwenqiang, Secretary of the Party committee of CCID Research Institute, lijinchun, chief expert of the review and Certification Center, chenxingshu, Dean of the school of Cyberspace Security of Sichuan University, Chenxin, chairman of China Network Security, haozhiqiang, deputy director of the first Institute of electronics, and Weiliang, deputy president of the Chinese Academy of communications and communications; An Hui, deputy chief engineer of CCID Research Institute, zhouhongyi, chairman of 360, Qi Xiangdong, chairman of qi'anxin, zhangzhaolong, founder of guan'an, Fanyuan, chairman of Anheng, and hezhaoxi, chairman of Shenxin, were appointed as standing members, and more than 80 experts and scholars from various industries were recruited as members. The Secretariat of the committee is set up in the China Software Evaluation Center, and Tanggang, assistant director, serves as the Secretary General. Zhengjianhua, director of the expert committee and academician of the Chinese Academy of Sciences, said that protecting national data security and citizens' legitimate privacy rights has become an important issue in front of the whole society and a key factor related to the real implementation of the big data strategy. The data security situation is still complex and the task is becoming more and more arduous. There is an urgent need for the government, enterprises, scientific research institutions, social organizations, users and other parties to work together to build a comprehensive and three-dimensional data security governance ecosystem.
