I reckon they are nastys, particluraly from a firewall or security admins perspective. The reason I liked ISA over many and just about all firewalls from a few years ago, was that it gave me "almost" complete control over what sort of "natsys" can either be downloaded or some how find there way into the house, and near a cd drive. The HTTP signature stuff was a huge shot in the arm for app blocking, and in a corporate sense you need to have that sort of control of the apps on a users computer otherwise you may as well put that "open all" firewall rule at number one spot on the grid, IMO.

Take Skype for an example, you don't even have to tell it any firewall information; it does its own probes and figures out how it can get through. Getting a bit more difficult to filter the tunnelers, they look like normal web traffic... What's your take on them? -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Wednesday, April 13, 2005 22:19 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Terminal Service Port Change? http://www.ISAserver.org Hey Jim, You being in the belly of the beast, as it were, you might have some insight into why developers of network enabled application don't seem to realize that there are these fancy things called "firewalls" that control access to and from the Internet, you know, for security reasons and stuff. Did they miss that meeting, or not even get the memo?
