文档介绍：网络病毒过滤的ACL规则
摘要
随着网络技术的不断发展,出现了大量的基于网络的服务,网络安全问题也就变得越来越重要。ACL即访问控制列表,它是工作在OSI参考模型三层以上设备,通过对数据包中的第三、四层中的包头信息按照给定的规则进行分析,判断是否转发该数据包。基于ACL的网络病毒的过滤技术在一定程度上可以比较好的保护局域网用户免遭外界病毒的干扰,是一种比较好的中小型局域网网络安全控制技术。
本设计重点从计算机网络病毒的出现、基本特征以及发展现状的角度出发,比较深入的研究了相关网络安全技术,深入分析了当前几种严重影响网络性能的网络病毒,结合ACL的工作原理,制定了相应的访问控制规则列表,并且通过模拟实验,对ACL的可行性进行了相应的测试。

Abstract
Along with work technology developing continuously, appear a great deal of services according to work, the safe problem work also es more and more important ACL namely Access Control List, it works on the equipments of the third or the fourth layer of the OSI model. By analyzing the passing data packets that including the head information of the third or fourth layers according to some the given rules, and then decided whether to deliver them. work technology based on ACL can protect local work goodly to encounter the outside virus. It is a kind of work safety control technique of small and middle scaled bureau.
This design point sets out from the emergence, basic characteristic of the work virus and the point of the development present condition, studying the safe technique of work more and thoroughly, thorough analyzed work virus of current that serious influence work, combine the ACL work principle, draw up a homologous access control rule list, and by imitate experimentation, carrying on the homologous test to the p
