Design and Implementation of Enterprise Network Security System Based on Firewall

With the rapid development of the network, in recent years, the Internet has greatly improved people’s lives, and the real-time, sharing and distance-removing characteristics of network information transmission have made the operation and management of enterprises more efficient and coordinated. The basis of refinement. At the same time, various network security incidents have followed, such as hacker attacks on computer network systems, and various types of viruses, Trojans and other active attacks emerge one after another. In this regard, this paper analyzes the enterprise network security system of firewall from the perspective of enterprise network security, briefly summarizes the background, advantages and disadvantages of firewall technology, and designs and implements a client software according to the actual needs of users. The network performs real-time intelligent security monitoring. After the system design is completed, the security is tested by building a simulation platform, including qualitative testing and quantitative testing, which are divided into security and performance to verify whether the system can achieve and guarantee performance.
