Firewall revolution or evolution?
Firewalls are again becoming talk of the town. There are an enormous amount of opinions including claims of a recent firewall revolution that have been proposed to completely change the firewall landscape. I will be the first to admit that the features and capabilities offered in today's firewall products are not the same as was offered in their original incarnation. But then again, traffic patterns and applications are not the same as they were when firewalls first hit the market.
