Discussion and Practice of Computer Network Information and Network Security Protection Strategy

With the development of science and technology, especially the application of big data technology, the role of computer networks has become more and more significant. Computer network has a profound impact on people's life and work, and has even become a part of life and work. However, computer network technology has also exposed some problems while providing convenience to people's lives. For example, the resulting information security issues pose a threat to people's personal privacy, corporate security, national security, etc., thereby affecting the sustainable development of computer network technology. Based on this, we must strengthen the research on computer network security. In particular, it is necessary to strengthen the research on the phenomenon of computer network information leakage and its causes, and strengthen the computer network security management. At the same time, we should also take necessary preventive measures from both technical and management aspects to ensure the safety of computer network information and reduce computer network threats. In view of this, this article will analyze and explore the current factors affecting computer network security on the basis of related concepts of computer network information security. The author analyzes how we should strengthen defenses from the perspective of technology and management to ensure the security of network information.
