The Problems and Countermeasures of Computer Network Information Security

The development and progress of science and technology has accelerated the optimization and perfection of network technology, which has made network technology widely used. The daily life of modern people cannot do without computers, and the Internet has become an important channel for people to understand and communicate. At present, more and more people use the Internet, and more and more problems are exposed in computer network information security. In recent years, information security issues have become increasingly prominent, which has caused many people's private information to be leaked, resulting in many losses. This article analyzes in detail the natural threats and man-made threats facing the current computer network information security. On this basis, the author puts forward that in order to maintain and guarantee the security of computer network information, we should face up to the problem of computer network information security, and combine science and technology to actively improve the information security protection system. We should install a firewall on the computer as soon as possible, and attach importance to the application of information encryption and authentication technology. In addition, we should also apply digital watermarking technology. The author hopes that this article can provide references for related researchers.
