具体描述

This book is a comprehensive guide to using Openswan for building both basic and industry size, military strength VPNs for medium to very large organizations. Written by the core developers, this practical book is all you need to use Openswan to build any VPN infrastructure you may need. The authors have covered the latest developments and upcoming issues. This book will not only help you build the VPN you need, but also save you a lot of time.

With the widespread use of wireless and the integration of VPN capabilities in most modern laptops, PDA's and mobile phones, there is a growing desire for encrypting more and more communications to prevent eavesdropping. Can you trust the coffee shop's wireless network? Is your neighbor watching your wireless? Or are your competitors perhaps engaged in industrial espionage? Do you need to send information back to your office while on the road or on board a ship? Or do you just want to securely access your MP3's at home? IPsec is the industry standard for encrypted communication, and Openswan is the de-facto implementation of IPsec for Linux.

Whether you are just connecting your home DSL connection with your laptop when you're on the road to access your files at home, or you are building an industry size, military strength VPN infrastructure for a medium to very large organization, this book will assist you in setting up Openswan to suit those needs.

The topics discussed range from designing, to building, to configuring Openswan as the VPN gateway to deploy IPsec using Openswan. It not only for Linux clients, but also the more commonly used Operating Systems such as Microsoft Windows and MacOSX. Furthermore it discusses common interoperability examples for third party vendors, such as Cisco, Checkpoint, Netscreen and other common IPsec vendors.

The authors bring you first hand information, as they are the official developers of the Openswan code. They have included the latest developments and upcoming issues. With experience in answering questions on a daily basis on the mailing lists since the creation of Openswan, the authors are by far the most experienced in a wide range of successful and not so successful uses of Openswan by people worldwide.

作者简介

Paul Wouters has been involved with Linux networking and security since he co-founded the Dutch ISP Xtended Internet back in 1996, where he started working with FreeS/WAN IPsec in 1999 and with DNSSEC for the .nl domain in 2001.

He has been writing since 1997, when his first article about network security was published in Linux Journal in 1997. Since then, he has written mostly for the Dutch spin-off of the German c't magazine, focusing on Linux, networking, and the impact of the digital world on society.

He has presented papers at SANS, OSA, CCC, HAL, BlackHat, and Defcon, and several other smaller conferences.

He started working for Xelerance in 2003, focusing on IPsec, DNSSEC, Radius, and training delivery.

Ken Bantoft started programming in 1988, and successfully avoided it as a full-time job until 2002. Before that, he opted instead to focus on Unix, Networking, and Linux integration.

Beginning at OLS2002, he started working alongside the FreeS/WAN project, integrating various patches into his own fork of its code—Super FreeS/WAN, which is now known as Openswan.

He currently lives in Oakville, ON, Canada, with his wife Van, two cats, and too many computers.

Ken started working for Xelerance in 2003 where he works mostly on IPsec, BGP/OSPF, Asterisk, LDAP, and Radius.

用户评价

这本书的价值，最终体现在它能够为读者带来多大的信心和自主性。在我尝试按照书中的指导配置一个复杂的、跨越不同子网和不同操作系统平台的VPN连接时，我发现我可以完全信赖书中所提供的步骤和参数。这种信任感并非盲目的，而是源于作者在每一步骤后都清晰地解释了背后的安全原理和潜在风险点。最让我印象深刻的是，书中对未来趋势的展望，虽然篇幅不多，但其对新兴加密标准和零信任网络架构中VPN角色的预判，显示出作者不仅精通现有技术，更具备前瞻性的视野。读完这本书，我感觉自己不再是被动地执行命令，而是成为了一个能够主动设计、部署和维护高安全级别VPN基础设施的专家。它提供的那种坚实的技术基础和解决未知问题的能力，才是任何一本优秀技术书籍最核心的馈赠。这本书绝对是网络安全从业者工具箱中不可或缺的一块基石。

这本书的内容组织结构，简直可以被视为构建复杂网络安全架构的路线图。它并非简单地罗列命令和配置片段，而是以一种极富逻辑性和层次感的方式，引导读者从宏观的概念理解，逐步深入到微观的协议实现层面。我惊喜地发现，作者在引入每一个新概念时，都会先铺垫其在整个VPN生态系统中的角色和重要性，而不是突兀地抛出技术术语。特别是关于密钥交换和加密算法选择的章节，作者的处理方式非常巧妙，他没有止步于告诉我们“应该用什么”，而是深入剖析了不同算法在安全强度、性能开销以及兼容性之间的权衡艺术。这种深入浅出的叙事风格，极大地降低了初学者面对VPN技术时的心理门槛，同时也为资深工程师提供了重新审视基础和优化现有部署的全新视角。阅读过程中，我感觉自己不是在死记硬背配置脚本，而是在跟随一位经验丰富的架构师进行一次实战演练，每一步的决策都有其明确的理论支撑和实际应用场景的考量。

这本书的语言风格，可以说是教科书级别的严谨与实践经验的完美结合。它大量使用了精确的技术术语，这一点对于专业读者来说是极大的福音，因为它避免了任何模糊不清的表达，保证了指令和概念的准确无误。然而，更令人称道的是，在处理那些容易陷入枯燥的技术描述时，作者总能穿插一些精炼的案例分析或者类比说明，使得原本晦涩难懂的加密隧道建立过程变得生动起来。比如说，作者在解释IPsec协商过程时，引入了一个关于“握手安全”的生动比喻，瞬间让复杂的IKE阶段清晰可见。这种在学术深度和可读性之间的微妙平衡，是很多技术作者难以把握的。我发现自己很少需要频繁地跳回去查阅前文或搜索引擎，因为作者的行文逻辑已经将必要的背景知识以最有效率的方式嵌入到了当前章节的讲解之中。这种行文的流畅度和知识的承载密度，体现了作者深厚的专业功底和卓越的教学能力。

这本书的封面设计和装帧质量着实让人眼前一亮，那种低调而专业的色彩搭配，散发出一种技术书籍特有的沉稳感。我拿到手的时候，首先被它厚实的纸张和精良的印刷工艺所吸引，这在当前这个追求快速迭代、内容为王的时代，实属难得。书脊的字体选择也十分考究，既保证了清晰易读，又透着一股经典的技术手册味道。我特别欣赏作者和出版社在细节上投入的精力，比如目录的排版逻辑非常清晰，索引部分的查找效率很高，这对于一本涉及复杂技术细节的著作来说至关重要。通常这类书籍在物理呈现上往往显得粗糙，但《Building and Integrating Virtual Private Networks with Openswan》显然打破了这一常规，它让人感觉这不仅仅是一本工具书，更像是一件值得收藏的专业文献。从触感、视觉体验到翻阅时的手感，都透露着一种对技术严谨性的尊重，让人在阅读之前就已经对内容产生了积极的期待，仿佛预示着接下来的学习旅程会是一次高质量的、令人愉悦的专业探索。这种对物理载体的重视，无疑提升了整体的阅读体验，是许多只注重电子版的现代书籍无法比拟的优势。

与其他市面上专注于特定工具集成的书籍相比，这本书在网络安全集成战略层面的探讨，展现出了远超预期的深度和广度。它不仅仅是一个关于Openswan工具集的说明书，更是一部关于如何将VPN解决方案无缝嵌入到现有异构网络环境中的战略指南。我特别关注了其中关于多站点互联和防火墙策略整合的部分，作者对不同网络拓扑下的路由策略和策略冲突解决提出了非常具有操作性的建议，这些建议明显是基于大量真实世界项目经验总结而来的。书中对性能调优和故障排除的章节，更是详尽到令人称赞的地步，它不仅列出了常见的错误代码，更重要的是，它教会读者如何运用系统级的诊断工具来追踪问题的根源，而不是仅仅停留在配置文件的表面修改。这种从“如何做”到“为什么这么做以及如何修正做错的地方”的思维拓展，极大地提升了读者解决复杂问题的能力，让这本书的价值超越了其作为技术手册的定位，上升到了架构设计顾问的层面。
