How secure is a whitelisting firewall?
Posted on 2011-09-07
I have a computer with very narrow focus of purpose, it's just going to connect to a couple of commercial services via internet, they have state of the art firewalls. My browser is never going to be used except for setting up a hardware firewall via LAN. Said hardware firewall is set up to allow traffic [whitelisted] on only the handful of numerical [bypassing the DNS's seems a good thing to do for the sake of "less moving parts" if nothing else] url's required to access servers at the abovementioned commercial institutions, and the hardware firewall does Stateful Packet Inspection [url's cannot be spoofed, right?], is it at all possible for entry to be gained to my computer from any computer not at the places allowed by the whitelist?
