TuxGuardian was developed after the observation that Linux security
applications were not tailored for lay users. With TuxGuardian

Operates with or without user intervention;
Verifies the applications' integrity so that maliciously modified

In what situations should I use TuxGuardian?
If you want to protect you computer against spywares, trojans and
other evil pieces of software;
If you want to have an additional layer of protection working on
a per-application basis, besides a packet-filtering firewall or
other low level security mechanisms;
If you want to stop backdoors and rootkits which modify the
expected behavior of your applications from accessing the network;
If you want to implement the internal security of your network
(this is specially useful since ordinary firewalls usually only
take care of external threats);
If you want to implement an extra security layer in your network,
in addition to the one provided by institutional firewalls and
