Book Abstract

第1章 开源软件的商业应用案例
引言
也许你在寻求一种廉价的方法来解决系统安全问题,并且想了解更多的免费软件。
将指导你学习一些最佳解决方案,它们使得Red Hat Linux更加安全。在有些环境下,不管是否有一个完善的计划,提议和实施任何类型的安全措施都会引发问题。本章给予必要的帮助和支持,以实现一个节省开支的方案。
人们常常扮演两种角色:一,实施安全性改进,期望上级接受方案;二,你是一位决策者,需要了解某个“免费”的解决方案实际含义,不论你是哪种人,本章都会找到解决办法。本章讨论了使用免费软件时的隐性开销,揭示开销的来源。本章还谈到这样的事实:在多数情况下,一个免费软件与一个商业产品,在统一标准下进行公平的比较是不切实际的。掌握了上述信息,你就能够在提出方案时占得先机,也能使自己的观点更有商业说服力。
使用免费方案的花费
在安全问题解决方案的案例中,几乎没有什么东西是终生免费的。可能一个方案本身无需付费,但方案的实现却是有开销的,而这一点很容易被忽略。在多数案例中,选择哪个解决方案取决于其安全性的需求,如果没有可用的免费方案,就不得不使用商业化的工具。然而幸运的是,世界上有很多高质量的免费方案。本书后面章节里也有这方面的内容,目的是对解决方案给予不同深度的描述。如果没有足够的知识和调研就轻率地开始实施一种免费的方案,这可能会比使用商业方案花费更多的经费。
培训费用
当采用一种免费的解决方案时,培训费用是最大的开支之一。其一是直接的培训费用(如送某人去参加课堂学习)。当需要针对免费软件进行培训时,几乎别无选择。多数情况下,培训课程并不具有很强的针对性(例如,恐怕找不到netfilter防火墙的课程),然而可以参加一些问接的培训,如一般性的Linux使用或者系统管理课程。
另一项支出是材料费(如书本)。除现有资料外,可能有些领域需要专门的知识。例如部署一个Snort入侵检测系统(IDS),而现有资料只涉及了如何安装Snort,所以需要购买关于这个软件的其他图书。
还有一种培训代价,就是职员在培训期间无法工作。这期间他没有贡献,而你在支付资源,所以说员工离开工作岗位也是一种损失。即使员工在工作岗位自学培训内容,也同样是一种消耗。
Introduction

本书是一本非常实用的关于Linux系统网络安全配置的指导性读物。它涉及了几乎所有常见网络安全问题。内容上,理论与实践相结合,着重描述了各领域技术背景以及相应开源免费软件的使用。结构上,各章由浅人深依次展开,但又可以各自独立,一般不必以前文为基础。本书一大特点是,作者往往列举出多个类似的技术或功能相同的软件,进行横向比较,然后选择性地进行详述,这样帮助读者既获得广博的知识面,义能够精通一两项常用技能。
本书的主要目标读者为Linux系统管理员、安全管理员,以帮助他们选择采用哪种系统和技术,并提供了全面且深入的操作方法。Linux系统的使用者也有必要学习系统安全知识,了解网络安全特点,以在使用时多加注意。信息化建设相关人员、学生、网络安全研究人员以及广大对网络安全技术和网络安全软件感兴趣的人们,也可以从中获取有益的前沿信息和技术。
本书第1,2,3,6,9,10章由邱硕翻译,第5,7章由孙海滨翻译,第4,8章南刘乙璇翻译,第11章由刘鹏友情翻译。全书由邱硕统一修改并定稿。特别感谢博士生刘笑寒、李安南和孙国栋,他们为本书的译稿做出了重要的贡献。
原书语言流畅,内容严谨,具有极强的实用性和可操作性。译者力求反映原书的风貌和特点,但由于时间以及水平有限,不当和疏漏之处在所难免,恳请广大读者批评指正。我们的电子邮箱是qiushawn@yahoo.com。
