How can development and security complement each other and consolidate the security foundation for high-quality development of the digital economy? At the 2022 China international big data industry expo held recently, representatives from the government, enterprises and academia gathered in the "cloud" for in-depth exchanges. They agreed to effectively enhance the security capability to deal with data risks. "Data has become an important factor of production and a new engine for promoting the quality, efficiency and dynamics of economic development." Du Guangda, deputy director of the network security administration of the Ministry of industry and information technology, said 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 high-quality economic and social development. "While big data brings huge economic and social benefits, it also poses new challenges to data security and privacy protection." Zhengjianhua, an academician of the Chinese Academy of Sciences, believes that ensuring the security of data in the whole life cycle of collection, transmission, storage, transaction, sharing, use and destruction, and protecting national data security and citizens' privacy has become an important issue in front of the whole society. In recent years, China has issued data security law, personal information protection law and other laws as well as relevant supporting rules, and the data security guarantee system is becoming more and more perfect. Huang Qingqing, vice president of the Internet Society of China, said that the intensive release of policies and measures related to data security is conducive to promoting the rapid growth of data security enterprises, research and service institutions, and is of great significance to expand the data security industry, improve the data security guarantee capacity, and promote the innovative application of data. With the deepening of digitalization, digital technologies such as 5g, artificial intelligence and big data have accelerated their enabling applications. Data elements are deeply integrated with the application scenarios of thousands of banks and industries. New scenarios, new businesses and new models have also brought new changes to data security. Weiliang, vice president of China information and Communication Research Institute, said: "large scale data sharing, business collaboration and information system interconnection require that data security must be an all-round, full process and systematic integration." "Data classification and classification is the most basic and important work to do a good job in data security." Haozhiqiang, deputy director of the national industrial information security development research center, said that it is necessary to sort out the base number of data assets scientifically and intuitively through data classification and classification, identify important data and core data, establish and improve the data classification and classification management mechanism, submit important data and core data directories level by level, and compact responsibilities layer by layer. In recent years, China's data security industry has made great progress, but there are also many problems to be solved. Liuwenqiang, Secretary of the Party committee and vice president of China Electronic Information Industry Development Research Institute, believes that there are still some problems in the current development of the data security industry, such as serious homogenization of technical products, market players fighting on their own, failure to form a unified standard system, insufficient toughness of the product supply chain, and imperfect technical product system. In addition, the problem of insufficient talent reserve in the data security industry is also prominent. Enterprises generally say that there is a shortage of data security professionals.
