Harden-environment provides a hardened system environment, or at least helps the administrator to configure such an environment.

right now this includes packages for local intrusion detection.

note! this package will not make your system uncrackable, and it is not intended to do so. making your system secure involves a lot more than just installing a package.

for more information on how to secure your system see: http://www.debian.org/doc/manuals/securing-debian-howto/
