随着计算机网络的迅猛发展,网络的安全问题也越来越引起人们的重视.防火墙作为一种有效的安全防护措施被广泛应用于各种类型的网络当中.防火墙技术经历了多个阶段的改进与发展,然而无论是传统的边界防火墙,还是目前流行的分布式防火墙,都有其各自的缺陷及不足,使得其在实际使用中受到很多限制.
本设计实现的防火墙采用NDIS中间层驱动过滤技术,NDIS驱动是内核驱动,它实现一个过滤回调函数,并用系统提供的IP过滤驱动注册它,IP过滤驱动随后使用这个驱动来决定如何处理进出系统的数据包.防火墙由以下几个模块组成：过滤规则添加模块,过滤规则显示模块,过滤规则存储模块,文件储存模块,安装卸载规则模块,IP封包过滤驱动功能模块.用户只需要通过主界面菜单和按钮就可以灵活地操作防火墙,有效地保护Windows系统的安全.
该方案是对传统防火墙技术与分布式防火墙技术的折衷,既能克服传统防火墙的单失效点及内部不安全等问题,又能避免分布式防火墙的过于集中管理所带来的问题.本文提出了一种基于决策树分类器的数据包分类算法.其主要思想是通过预处理,利用规则集的结构特点构建一个决策...

With the rapid development of computer networks,network security issues are increasingly attracted our attention.Firewall as an effective security measure is widely used in various types of networks.Firewall technology has experienced a number of improvements and development stage.However,whether the traditional firewall or currently popular distributed firewall all have their own weaknesses,making their use in practice many restrictions.
This design has implemented a firewall adopting the NDIS driver technology.It’s driven through the kernel mode,the NDIS callback function has been implemented and the filter-hook driver is registered by the NDIS which is provided by system.The IP filter driver uses the filter-hook to handle the data packets in and out.The firewall is composed of the following modules:adding filter rules module,display filter rules module storage filter rules module,storage file module,installation unloading rules module and IP packet driver module.Users can finish the operation of firewall by using main menu and button to protect the system effectively.
The program is a traditional firewall technology and distributed firewall technology combined.The firewall can overcome the internal insecurity and other issues.And also can avoid too much focus on the distributed firewall management problems.In this paper a decision tree based on packet classification algorithms.The main idea is the pre-treatment rules to build the decision-making tree of structural characteristics.
