There are companies that make appliances that can do application layer filtering and/or QoS. We're playing around with a Packeteer PacketShaper here, and so far, we're pretty impressed with what it can do. Among the layer 7 traffic it can regulate are all the common IM services, but there are a whole bunch of other protocols that you can work with as well - VOIP, file sharing, etc. Devin -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of Dixon, Wayne Sent: Friday, March 23, 2007 5:39 PM To: nawalmiftahi () gmail com; security-basics () securityfocus com Subject: RE: how to block web messenger services Short of a proxy to block the specific addresses, I myself, can't think of anyway, since the web services connect to the back end server of the IM services; and the only connection from your site to the web service site is via HTTP, I can't think of any other way.
