Research on key technology of computer network defense

Abstract

Computer network technology has been widely used in all walks of life in China under the acceleration of scientific and technological upgrading. In all aspects of social production and people's lives, we can see the use of the computer network scenarios. A good computer network environment can ensure that citizens' personal information will not be leaked for no reason and the health of computers themselves. At the same time, there is a trend of diversified development of computer network attack means. So as to improve computer network's security, we need to explore and analyze the key technologies of computer network defense so as to prepare for the loss or leakage of information and data in computer network. Based on today's information situation, this paper analyzes today's network environment, points out the necessity of network defense technology for us, and hopes that China's information defense technology will be strengthened day by day.
