Narus to Present at NANOG Conference

Presentation Will Explore How "Googling" the Internet Can Help Service Providers Augment Business and Protect Networks

LOS ANGELES, CA--(Marketwire - October 14, 2008) -

WHAT:    "Unconstrained Profiling of Internet Endpoints via Information on
         the Web"

         In order to better manage and protect their networks, operators
         in the Security Operations Center of an ISP may need to discover
         more about an IP address. Operators will often look that IP
         address up on Google to establish what else it has been doing on
         the Internet. If, for example, the operator can establish that
         the IP address attacking its network with a DDoS flood has also
         been blacklisted by a reputation blacklist in the past for either
         being a spammer or a bot-infected host, then it provides further
         evidence about the origins of the flood. This can be important
         in understanding the intent behind an attack. However, such
         Google searches can be laborious and frustrating, as canvassing
         the results is a monumental task. A more efficient approach is
         needed, by organizing all information about IP addresses found on
         the Web via keywords that denote their use. Using this approach,
         operators will have all pertinent information at their fingertips.

         In this presentation, "Unconstrained Profiling of Internet
         Endpoints via Information on the Web," Narus introduces a novel
         approach for profiling and classifying endpoints (i.e. IP
         addresses). This technique can be used by service providers to
         classify network traffic for traffic management. We implemented
         and deployed a Google-based profiling tool, which accurately
         characterizes endpoint behavior by collecting and strategically
         combining information freely available on the Web. We will show
         how classification of endpoints can assist in categorizing
         traffic into classes such as Web, peer-to-peer, gaming, chat,

         Furthermore, this method can even identify semantically richer
         categories such as for chat. In that case, we can even identify
         MSN chat vs. Yahoo! messenger. This traffic classification works
         even under scenarios of high packet sampling, and is
         port-agnostic. Finally, using this approach, we perform
         unconstrained endpoint profiling at a global scale, for clients
         in four different world regions (Asia, South and North America,
         and Europe). We provide the first-of-its kind endpoint analysis
         that reveals fascinating similarities and differences in
         application usage among these regions.
