Bastille linux is a security hardening program for gnu/linux. it increases the security of the system either by disabling services (if they are not necessary) or by altering their configuration.

if run in the (recommended) interactive mode, bastille educates the administrator during the hardening process: in each step of the process, extensive descriptions are given of what security issues are involved. each step is optional. if run in the quicker automated mode, bastille hardens the system according the profile chosen.

bastille linux works for several linux distributions. this package has been specifically modified to work for debian gnu/linux.
