How to Cheat at Securing Linux

by James Stanger

Overview

Linux servers now account for 33% of all networks servers running worldwide (Source: IDC). The top 3 market share holders in the network server space (IBM, Hewlett-Packard, and Dell) all use Linux as their standard operating system.

This book teaches Linux system administrators how to protect their servers from malicious threats.

As with any technologies, increased usage results in increased attention from malicious hackers. For years a myth existed that Windows was inherently less secure than Linux, because there were significantly more attacks against Windows machines than Linux. This was a fallacy. There were more attacks against Windows machines because there were simply so many more Windows machines to attack. Now, the numbers tell the exact opposite story. Linux servers account for 1/3 of all servers worldwide, but in 2005 there were 3 times as many high-severity security vulnerabilities discovered on Linux servers (Source: IDC).

This book covers Open Source security, implementing an intrusion detection system, unearthing Rootkits, defending against malware, creating Virtual Private Networks, and much more.

Editorial Reviews

This is a comprehensive, modern guide to securing today's Linux systems and networks. Think of it as "defense in depth" in depth: detailed guidance on using open source tools for everything from rootkit detection to protecting your databases.

James Stanger starts with a high-level assessment of the pros and cons of free solutions, plus guidance on evaluating specific open source options. Next, you'll walk through hardening Linux boxes and other devices inside your network perimeter (avoiding the "hard exterior/soft squishy interior" malady that affects so many networks). Stanger shows how to penetration-test your systems, then thoroughly covers Snort intrusion detection (including significant enhancements in version 2.6).

Also covered in depth: authentication; firewalling; resisting sniffing attacks; toughening perimeter security with VPNs; using bastion hosts; and hardening Apache. Throughout, you'll find loads of diagrams, sample commands, and tips: all you need to actually do this stuff. Bill Camarda, from the December 2007 Read Only
