"Our mission , and the reason we are different from say Akonix or IMlogic , is that we are not just looking at IM, we look more broadly at real-time applications, including WebEx, collaboration software, peer-to-peer applications, and SSL VPNs," says Srini Gurrapu, FaceTime's vice president of product management.
He believes real-time applications for conferencing, collaboration, VoIP, and IM will all begin to merge together in more integrated applications.Therefore, the challenge for IM security companies, he believes, is to understand that IM is just a subset of real-time applications, and customers are after protection and management tools that apply to all real time applications, not just IM applications."If, for example, we don't have the technology to secure P2P channels, then we are not addressing the problems of our customers.So we need to have a more comprehensive offering than just IM tools," says Gurrapu.
The problem with managing and protecting against many P2P based applications - which can include IM - is that they can port crawl and their protocols change frequently, so they can be difficult to detect.To get around this FaceTime does not rely in signature recognition exclusively, but also uses behavior analysis - which includes detecting the presence "heartbeat" of many real time applications - deep flow analysis and statistical techniques to recognize unwanted applications for what they are as packets enter or leave the network.
For the moment, Gurrapu says Skype is causing the most headaches, although many of these will be overcome in the coming months."Skype is the largest IM network and it gets anywhere," he says.
