RE: VPN is a Backdoor !!! [7:27725]

2001-11-29 Thread Gibb, Jake

VPN could be considered a backdoor. If Joe User has a broadband
connection at home with no firewall or local client firewall installed
then when he/she connects to your VPN that is essentially a conduit for
attackers to potentially compromise. This is an issue that I am dealing
with now. Ciscos VPN client and Concentrator has a new feature that will
push a policy on the client requiring they have a firewall installed
like BlackIce etc.. If they don't it will enforce it's own basic
firewall on the client while connected. I am working on the scripted
install for my company now.

Even then though, you're not secure.  If the box is compromised before you
connect then even when the firewall is enforced, malicious activity could
still take a place...the attacker would not be able to connect to the
machine but could leave dastardly code behind to do his job for him.

I am working on this scenario now as well.  I am attempting to come up with
a best practice for cleaning a machine, installing a firewall, etc for
any vpn client.  Let me know how yours goes!
