Bastille  is  a  system hardening / lockdown program which enhances the
security of a Unix host.  It configures daemons, system settings and 
firewalls to be more secure.  It can shut off unneeded services
like rcp and rlogin, and helps create "chroot jails" that help limit the
vulnerability of common Internet services like Web services and DNS.

This tool currently hardens Red Hat (Fedora Core, Enterprise and Legacy/Classic),
SuSE, Debian, Gentoo, Mandrake Linux, HP-UX, and Turbo Linux.

If run in the preferred interactive mode, it can teach you a good deal about 
security while personalizing your system security state.

To install:

Please use the distribution-specific method for installation.  On
Red Hat, Mandrake and SuSE, this involves installing the RPM.  On Debian,
you should use apt-get or download the deb package.  On Gentoo, please use
emerge.  Finally, on HP-UX, please use your vendor supplied package.  See
www.bastille-linux.org for more information.

To run:

bastille [(-b|-c|-r|-x)]

 -b : use a saved config file to apply changes directly to system
 -c : use the Curses (non-X11) GUI (Linux only)
 -r : revert Bastille changes to original file versions (pre-Bastille)
 -x : use the Perl/Tk (X11) GUI
