"In 1999, Linux was the only server-class operating system to increase its market share. Not even Windows NT did that. Linux has entered into prime time."
"Linux offers an incredible wealth of tools and services, the bulk of which are completely open source. With its new-found popularity, security is now becoming an ever-increasing concern. Once the playground of computer hackers who generally knew the principles of securing their systems, Linux is now beginning to be used by the computer novice who reads about it in magazines or sees it on TV and decides to try it. Security is often an afterthought. When they want to secure their system, novice users don't know where to begin. With the recent rise of new attack tools that can use multiple systems to flood commercial sites, unsecured systems become a serious threat to the well being of the Internet."
"This series of articles is designed to help users secure their Linux systems. I will describe methods that attackers use to gain information and access systems. I will then discuss countermeasures for defeating these attacks. Finally, I will list Web sites, mailing lists and books where you can find more information, including the latest vulnerabilities and attacks. It is important to emphasize that security is not a one-time proposition. You need to continue to update your system. As new attacks are discovered, new defenses will need to be implemented."
