This package is intended to help the administrator to improve the security of the system, or at least make the host less susceptible.

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. you are recommended to read at least some documents in addition to installing this package.

there is a lot of information available on making your system more secure. a good place to start is with the harden-doc package or at http://www.debian.org/doc/manuals/securing-debian-howto/
