"Security is never a luxury. It can save money, time, and frustration. The Linux operating system...has several built-in security mechanisms, which are unfortunately rarely used. This article explores the basic aspects of securing a Linux server."
"Start with a fresh install. Any security expert will tell you that there is no use securing a system when you don't know whether break-ins and backdoors already have been created. Any Linux distribution will work fine, because they all contain the required security tools. You should install and configure the Linux system before connecting it to the Internet. Linux installation is relatively simple regardless of the distribution you pick - the security configuration happens after the installation."
"Basic security on a Linux system is very similar to other UNIX systems. Areas to configure include user security, network security, and kernel parameters. This article reviews all of these areas, including more advanced ways to add security to Linux and some sites that contain more information."
