【正文】 完成時間 基于 ISA Server 防火墻的設(shè)計和實現(xiàn) 1 基于 ISA Server 防火墻的設(shè)計和實現(xiàn) 摘 要 隨著網(wǎng)絡(luò)的發(fā)展，人們對信息的安全也越來越重視，正是因為這樣才推動了防火墻的快速發(fā)展， ISA 是防火墻的軟件技術(shù)， 目前 ISA（ Inter Security Acceleration） 的版本有 ISA2021 ISA2021 ISA2021 ISA2021，是一款微軟出品的著名路由級網(wǎng)絡(luò)防火 墻。 ISA 服務(wù)器在 2021 年提供組織以能力鞏固從現(xiàn)代計算的世界的 盤剝和威脅的重要企業(yè)基礎(chǔ)設(shè)施的一個健壯應(yīng)用層防火墻。 關(guān)鍵 字 ISA /VPN /防火墻 基于 ISA Server 防火墻的設(shè)計和實現(xiàn) 2 Based On ISA Server Firewall Design and Implementation ABSTRACT With the development of the work, people are more and more attention to the security of information, precisely because this was to promote the rapid development of firewall, ISA is a firewall software technology, the current ISA (Inter Security Acceleration) version has ISA2021 ISA2021 ISA2021 ISA2021 , is a Microsoft prod uced a wellknown route level work firewall. ISA Server 2021 provides aniza tions the ability to consolidate the world from the exploitation of modern puting and a major threat to a robust enterprise infrastructure application layer firewall. In this paper, ISA Server 2021 firewall in the enterprise to realize the important role of the work, by telling it to install and configure ISA as a firewall and a brief border ISA Server 2021, VPN on demand is now especially for small business users to that the pursuit of safe and affordable way to build only with ISA Server VPN, this paper introduces VPN, VPN set up to serve you on the use of VPN, and then constructed by using the ISA VPN to achieve between the two head office and branch offices secure munications, and work environment using simulated test work connectivity and firewall systems KEY WORDS ISA ,VPN ,Firewall 基于 ISA Server 防火墻的設(shè)計和實現(xiàn) 3 目 錄 ..................................................................................................................... 1 什么是防火墻？ ........................................................................................ 1 防火墻的工作原理 ................................................................................... 1 防火墻能做什么？ ................................................................................... 6 2 ISA Server ......................................................................................................... 8 ISA Server 簡介 ................................................................................... 8 ISA Server 的作用 .............................................................................. 8 安全服務(wù)發(fā)布 ......................................................................................... 9 正向 Web 緩存服務(wù)器 ........................................................................... 9 反向 Web 緩存服務(wù)器 ........................................................................... 9 防火墻和 Web 緩存集成服務(wù)器 ........................................................ 9 3 安裝 ISA Server 2021 ................................................................................. 10 安裝步驟 ................................................................................................ 10 驗證 ISA Server 2021 安裝效果 ..................................................... 12 4. 構(gòu)建 VPN ............................................................................................................. 13 簡介 ............................................................................................................. 13 功能 ............................................................................................................. 13 常用的虛擬私人網(wǎng)絡(luò)協(xié)議 ................................................................... 13 用 ISA2021 搭建 VPN 服務(wù)器 .............................................................. 14 ISA Server 集成的 VPN 特性 ........................................................... 14 構(gòu)建一個安全穩(wěn)定的 VPN 服務(wù)器操作系統(tǒng)平臺 .......................... 15 定義 VPN 地址池 ................................................................................ 15 基于 ISA Server 防火墻的設(shè)計和實現(xiàn) 4 配置 VPN 服務(wù)器 ................................................................................ 17 網(wǎng)絡(luò)規(guī)則 ............................................................................................. 18 防火墻策略 ........................................................................................ 18 用戶撥入權(quán)限 .................................................................................. 18 5. 結(jié)束語 .................................................................................................................
