Computer Network Security Maintenance and Management in the Era of Big Data

Abstract

With the development of information technology, the big data network has been initially formed. However, the network security problem is becoming more and more serious in this environment. China has put the network security in an important position of national security. This paper analyzes the text of China's network security governance policy from the perspective of big data, builds an analysis framework based on big data, analyzes the relevant provisions of China's network security governance policy, analyzes the existing problems and puts forward optimization suggestions, in order to provide reference for the formulation of China's network security governance policy and improve China's network security governance policy system. This paper collects the information of network security incidents and policies in 2020 from Google data analysis platform. After preliminary collection and sorting, 195 relevant policies on network security governance are obtained. In order to ensure the accuracy and pertinence of the materials, all policies are analyzed. The research results show that the application of some big data of network security governance is concentrated on the regulatory level, lacking specific implementation rules and methods. There are 183 policies involving regulatory control, accounting for 31.6%. Therefore, the national network information department should cooperate with the legislative department to formulate policies for the problems in the network ecosystem. Network is not only the extension of people's daily life, but also an important part of economic and social life.
