Challenges And Countermeasures Of China For National Big Data Security In Global Cyberspace

The booming development of the Internet has accelerated the process of human informationization.With the massive growth of various data,big data came into being.Big data contains important information about the survival,development and security of the country.It is the key to the promotion of power and the initiative of state actors and non-state actors in international competition.The acquisition,control and utilization of big data resources are becoming An important goal of international competition.However,due to the global,virtual,interactive,open,low-cost nature of the Internet,and the existence of global cyberspace technology hegemony and divide,the security of big data relying on the rapid growth of the Internet faces many challenges.With threats.Therefore,it is of great significance to the maintenance of national big data security.Global cyberspace Big data security refers to the security of the big data lifecycle,that is,big data can maintain the authenticity and quality of data during the process of collection,flow,storage,application and destruction,and is not stolen and not leaked.The meaning of big data security in global cyberspace countries mainly means that big data security is related to national security,and big data can be used as a tool to maintain national security.In the global cyberspace,the challenges of national big data security are mainly three levels of technology,concept and system.First,technological challenges.The global Internet technology hegemony and the gap cause the big data to be stolen and intercepted;The anonymity of the Internet and the low barriers to entry have made the country's big data hacked by hackers and terrorist groups.Second,ideas challenge.The low threshold of Internet makes large data volume increase,but personal safety consciousness needs to be improved.Individual and enterprise overall national security view is relatively weak,easy to divulge national big data to threaten national security.Third,mechanism challenges.From an international perspective,the definition of the sovereignty of large data of cross-border flows is controversial;From the domestic point of view,large data generation,collection,storage,analysis,application of data ownership related to the lack of law;There is a serious shortage of large data technology-related talents.In view of the challenges to the large data security of the global cyberspace countries,taking China as an example,this paper puts forward the countermeasures to safeguard the large data security of the global cyberspace countries from three levels:first,the technical level.Maintaining Internet infrastructure security is the basic guarantee of national data security.The long-term goal of national data security is to improve the technological dominance at the physical level.Second,the concept of the level.Want to establish big data thinking;Strengthen the overall concept of national security;To enhance the international community's recognition of the public safety of large data.Third,mechanism level.To improve the international and domestic data ownership laws and regulations;Use or build a new global network space large-scale data security maintenance platform to achieve communication and cooperation;To realize limited sharing cooperation for maintaining large data security and to establish shared database.Big data security is related to the survival and development of the country.In the global cyberspace,China is a big Internet user.Although it has inherent advantages in the volume of big data,there are still shortcomings in the maintenance of big data security.China's big data strategy has a long way to go from "big" to "strong".China must not only maintain its own big data security,but also enhance its own strength.It must also play its due role in global cyberspace big data governance.Actively participate in the formulation of international big data security standards and take the initiative in future international competition.
