How to Cheat at Securing Linux
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.

there were 25).
