摘要
防火墙是网络安全防范的重要手段之一,但随着网络的进一步发展,传统防火墙的缺陷开始显露。论述了传统边界防火墙的主要缺陷,探讨了针对这些缺陷提出的新一代防火墙———分布式防火墙的原理、体系结构、本质特征、实现方法、应用领域及未来工作等问题。
The firewall is an important measure of network protection, but with the further development of network, the defaults of traditional firewalls begin to come out. This paper discusses the main defaults of traditional perimeter firewalls, and introduces the principle, architecture, essential character, implementation and application of distributed firewall which is a new generation firewall proposed to resolve the problems.
