Linux Security Quick Reference Guide

The intent of this Quick Reference Guide is to provide a starting point for improving the security of your system, to serve as a pointer to more in-depth security information, and to increase security awareness and methods that can be used to improve security. It is not a substitute for reading any of the vast amounts of Linux security documentation that already exists. [via]
