摘　　要：随着企业网络安全问题日益突出,防火墙技术的发展更加迅速,防火墙通常被放置在系统的边缘并作为流量的过滤器。随着网络攻击技术的多样化、复杂化,传统防火墙的缺陷逐渐显现,于是分布式防火墙应运而生。分布式防火墙是主机驻留式的网络安全系统,用以保护网络中的核心结点服务器、数据库和工作站以防止非法入侵的活动进行破坏。本文研究了分布式防火墙的体系结构和组件及其安全机制,分析了保障数据安全方面的性能和扩展应用。With network security becoming more and more important,the development of firewall technology is more rapid. A firewall is typically placed at the edge of a system and acts as a filter for unauthorized traffic. With the diversification of network attack, complexity of technology, the shortcomings of traditional firewall gradually emerge as the times require so the distributed firewaU. Distributed firewaU is a host resident secure system, to protect the network of key nodes, data server and workstation from illegal intrusion damage. The system structure and components are studied in this paper the distributed firewall, analyses the performance and extend the applications to ensure data security.
