I have a new network drive which is networked through my SMC Baricade Router (NAT Router).
My DSL Modem connects to the router and my computers also attach to the router. My computers all have Zone
Alarm Pro.
As I see it that drive is largely unprotected and is a potential open path into my computer and network What's the best way to protect that drive?

I realize that a NAT Router provides a certain level of protection but I don't think that's enough.

Operating System:Windows XP Home Edition
