Design of Enterprise Network Active Security Defense System Based on K-means Algorithm

With the rapid development of Internet technology, the scale of computer networks is also constantly expanding. Various industries have benefited from the Internet. Companies have gradually realized that the benefits of using Internet technology far outweigh the costs, so they began to use the Internet. When new technologies and new products are released, they will quickly add these new technologies and new products. This article first analyzes the network security of enterprises. According to the current network security situation, the current enterprise network security issues are summarized, and various security threats caused by external network attacks and internal users of the enterprise are analyzed, and corresponding countermeasures are given as a design guide and reference for the enterprise network security protection system. The experimental results show that in the simulation of real network attacks, the accuracy of using K-means to identify attack threats is as high as 94.32%, which is significantly better than the other two types of algorithms; in addition, the information failure ratio verifies that this method can effectively defend against network attacks. Therefore, the use of K-means algorithm is of great research significance to the design of enterprise network active security defense system.This paper hopes that the application of K-means algorithm in enterprise network active security defense system can provide reference value for enterprise network security defense.
