Security Books
Authoritative technical books written for system administrators and security-conscious users who wish to protect their Linux systems from unauthorized intrusions and other external attacks.

Operating System
A Linux distribution, originally based on Red Hat Linux, designed for servers and with emphasis on strong security. The installation program allows the user to choose from a selection of pre-defined server classes, depending on the server's purpose, with all unneeded services turned off by default. For those who intend to install and test drive OpenNA Linux, beware that it cannot be installed on a pre-selected partition - the OS takes over the entire first hard disk.
