Whitelisting a firewall is the reverse of the normal firewall. The normal firewall starts out with the entire web open and closes off the threats. Whitelisting starts with the entire web closed off and opens a computer only to the url's specified by the user. I'd love to have some white listing software firewall setup... I could take my laptop anywhere and trade and not have to worry about hackers... I had a Hotbrick hardware firewall that would whitelist but they failed and the company went belly up. My experience with whitelisting for the trading computer was very positive but I can't haul a hardwire firewall around and adapt it to wifi and all that.... The discussions about white listing are few and far between, the commercial interests are in blacklisting software and commercial websites aren't going to promote whitelisting, they want you to find their sites... but basically, I don't want to find their sites with my trading computer... Is there some innate capabilities in Windows whereby I could select the url's that are allowed in? Is there some software that can do that? I found lots of stuff with parental controls that could whitelist email addresses and such but I want something very simple and basic where I put in the urls that can get past the firewall... I wonder how hard would it be for a programmer to write a whitelisting utility for Windows?
