I was referring to Linux Security Module which allows
to define access policies for an application e.g. which ports are
allowed to be used.

If the goal is just to block those ports you don't have to go through
half of the networking stack to figure out via an iptable rules that
this access is not allowed.

I am not sure if I understood your question correctly. In case you
are asking what netfilter is I would like pointing you to the
http://www.netfilter.org/ project page.

cheers,
daniel
