英文题目Firewall and Its Application in the work

摘要
网络技术在近几年的时间有了非常大的发展,经历了从无到有,从有到快;网上信息资源也是从匮乏到丰富多彩,应有尽有。但随着网络速度越来越快,资源越来越丰富,网络安全问题却也越来越严峻,网络安全防范对校园网的正常运行来讲也就显得十分重要。
在网络安全防范中,防火墙具有着不可或缺的地位。防火墙技术是在安全技术当中又是最简单,也是最有效的解决方案。它不仅过滤了来自外部的探测、扫描、拒绝服务等攻击,还能避免内网已中木马的主机系统信息泄露...
本论文在详细分析防火墙工作原理的基础上,提出一个功能较为完备、性能较好、防火墙系统的本身也较为安全的防火墙系统的设计方案,同时介绍了具体实现过程中的关键步骤和主要方法。该防火墙在通常的包过滤防火墙基础之上,又增加了MAC地址绑定和端口映射等功能,使之具有更完备、更实用、更稳固的特点。通过对于具有上述特点的防火墙的配置与测试工作,一方面使得所设计的防火墙系统本身具有高效、安全、实用的特点,另一方面也对今后在此基础上继续测试其它网络产品作好了一系列比较全面的准备工作。

ABSTRACT
work technology has got very great development in recent years, and the online information resources are developing from deficient to rich and colorful too, and fill with everything. But with the development of the , the safe work is ing more and more severe. work safe precaution seems very important for normal running of our work too
In work security guard against the firewall is a vital role in technology. the firewall is the safety of technology is the simplest and most effective solution. it is not only from the exploration and scanning services, to attack, we can avoid has been in information disclosure of the wooden puter...
This thesis put forward a function in detailed analysis firewall working the foundation of the principle plete function than good, fire wall system of oneself the design project of the too safe fire wall system, and introduces to realizes in a specific way at the same time key in the process step with main method. That firewall is in the usual a percolation firewall foundation on, increased again the MAC address bind to settle the special function in etc., making it have the fresh and clear characteristics. Pass to make fire wall that have the research of the above characteristics and development work, very much a firewall for developing system oneself have efficiently ,safety, practical characteristics, on the other hand too to from now on here foundation ascend develop continuously
