Securing Your Linux Computer With Bastille
Bastille Linux is a hardening tool which is very effective at locking down your system, and all it requires is a few minutes of your time! It is currently available for the major Linux distributions: SUSE, Mandrake (the available RPM should work with Mandriva), Fedora Core, Red Hat, Debian, and Gentoo, and it is also available for HP-UX and Mac OS X, as well as the source code which can be compiled on most *nix systems. In this tutorial I shall take you through the steps of installing it and setting it up properly in order to secure your system better than before. Please note that this tutorial is designed for users new to Linux, and so may be slightly cumbersome for the more advanced users out there.
