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.

From the authors of the bestselling E-Mail Virus Protection Handbook! The Linux operating system continues to gain market share based largely on its reputation as being the most secure operating system available. The challenge faced by system administrators installing Linux is that it is secure only if installed and configured properly, constantly and meticulously updated, and carefully integrated with a wide variety of Open Source security tools. The fact that Linux source code is readily available to every hacker means that system administrators must continually learn security and anti-hacker techniques. Hack Proofing Linux will provide system administrators with all of the techniques necessary to properly configure and maintain Linux systems and counter malicious attacks. <ul>
<li>Linux operating systems and Open Source security tools are incredibly powerful, complex, and notoriously under-documented - this book addresses a real need</li>
<li>Uses forensics-based analysis to give the reader an insight to the mind of a hacker</li>
</ul>
