Yesterday I read another article bemoaning the large number of Window$
machines which have been commandeered remotely and turned into
spam-spewing zombies.
If I understand the matter correctly, a firewall can protect only
against incoming messages, and is useless against spyware which
"phones home" or zombie-ware which spews email spam.
So, before I preach about the dangers of spyware and zombies to my
buddies using Window$, how can I be certain that my own Debian machine
has not been compromised and has not become a zombie? Is there a
simple test which I can run on a weekly basis?
My LAN is protected by a machine running SmoothWall Express 2.0,
acting as a firewall and router. Would an internal firewall package be
useful in this environment?
