TuxGuardian is an application-based firewall that allows the
implementation of access control policies in order to identify
and control every application that tries to access the network.
It works with or without the intervention of the user by means
of a simple graphical interface. This means that a machine can
be made secure by controlling and forbidding transmission and
reception of data by unauthorized applications. It makes use of
the latest security mechanisms included in Linux 2.6 such as
the LSM framework.
