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 for the majority of their servers designed for medium to large size businesses. 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. But 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.

Linux operating system against general and specific threats.







The Linux Kernel (by David A Rusling)


This book is for Linux enthusiasts who want to know how the Linux kernel works. It is not an internals manual. Rather it describes the principles and mechanisms that Linux uses; how and why the Linux kernel works the way that it does. Linux is a moving target; this book is based upon the current, stable, 2.0.33 sources as those are what most
individuals and companies are now using.

Whether you are a systems administrator or desktop user, the book will show you commands to create file systems, troubleshoot networks, lock down security, and dig out almost anything you care to know about your Linux system.

This book’s focus for your Linux command-line journey is open SUSE, the community based Linux distribution sponsored by Novell, Inc. and SUSE Linux Enterprise. Tapping into the skills needed to run those systems can help you to work with your own Linux systems and to learn what you need as a Linux professional.
