The technologies of puter and information processing bee maturity. With the Inter and puter work technology to be flourishing, work security that has been widely concerned. Firewall system is one of the security technologies that used in the work. This design has implemented a firewall adopting the IP filterhook driver technology。 it’s driven through the kernel mode, the filterhook callback function has been implemented and the filterhook driver is registered by the IP filter driver which is provided by system. The IP filter driver uses the filterhook to handle the data packets in and out. The firewall is posed of the following modules: adding filter rules module, display filter rules module, storage filter rules module, storage file module, installation and unloading rules module, IP packet driver module. Users can finish the operation by using main menu and button and protect the system effectively. Key words: Firewall。 FilterHook。 Filter Driver。 Packet Filtering 目 錄 論文總頁數(shù)： 21 頁 1 引言 ............................................................................................................................. 1 課題背景 ............................................................................................................ 1 本課題研究意義 ................................................................................................. 1 本課題研究方法 ................................................................................................. 1 2 防火墻概述 .................................................................................................................. 1 防火墻的定義 ..................................................................................................... 1 防火墻的基本策略 .............................................................................................. 2 包過濾防火墻 ..................................................................................................... 2 數(shù)據(jù)包 ..................................................................................................................................... 2 包過濾防火墻的工作原理 .................................................................................................. 2 3 開發(fā)工具 ...................................................................................................................... 3 VISUAL C++ ................................................................................................... 3 VSS ................................................................................................................... 3 4 防火墻系統(tǒng)構(gòu)成 ........................................................................................................... 3 需求分析 ......................................................................................................................................... 3 設(shè)計思路 ......................................................................................................................................... 4 功能模塊構(gòu)成 ................................................................................................................................ 4 功能模塊介紹 ................................................................................................................................ 4 過濾規(guī)則添加刪除功能模塊 ........................................................................................... 4 過濾規(guī)則顯示功能模塊 .................................................................................................... 4 過濾規(guī)則存儲功能模塊 .................................................................................................... 5 文件存儲功能模塊 ............................................................................................................. 5 文件載入功能模塊 ............................................................................................................. 5 安裝卸載功能摸塊 ............................................................................................................. 5 IP 封包過濾驅(qū)動功能模塊 ............................................................................................... 5 5 防火墻設(shè)計 .................................................................................................................. 5 程序關(guān)鍵類 ........................................................................................................ 5 應(yīng)用程序類 CFireWallAPP .............................................................................................. 5 主框架類 CMainFrame...................................................................................................... 5 文檔類 CFireWallDoc ........................................................................................................ 6 視圖類 CFireWallView ...................................................................................................... 7 _RuleInfo 類 ........................................................................................................................ 7 詳細設(shè)計 ............................................................................................................ 8 主界面 ...............................................................................................................................
