Network Behavior Intelligence Streamlines and Automates Incident Resolution Process for Dartmouth College

ATLANTA — JUNE 14, 2005 — Lancope, Inc., the leading provider of Network Behavior Analysis (NBA) and Response solutions, today announced that Dartmouth College has deployed the award-winning StealthWatch system on its wireless network to defend against unknown attacks, reduce network outages and increase network stability. Dartmouth’s dynamic network supports an extensive user community of approximately 20,000 active students, researchers, faculty, staff and network devices.

“On Dartmouth’s open network, if a single system is compromised, it will generate enormous amounts of traffic, consume limited bandwidth and jam all systems on that wireless connection,”said Jason Jeffords, Director of Security Services for Dartmouth.“We needed a real-time solution, like StealthWatch, that could block incoming and outgoing attacks to prevent network outages and instability.”

“StealthWatch is ideally suited to protect large, heavily trafficked, distributed networks, like Dartmouth’s, ” said Harland LaVigne, Chairman, President and CEO of Lancope. “ We are excited to welcome Dartmouth, a leading technology innovator, to a growing roster of distinguished universities, including Stanford University, Northwestern University and University of North Carolina, who are turning to StealthWatch for behavior-based network security and intelligence.”

“During evaluation, StealthWatch was clearly effective at blocking and remediation. Immediately upon deployment, StealthWatch uncovered 400 misbehaving hosts and helped reduce network threats by 90 percent, ”Jeffords added. “ Email worms, which used to propagate quickly, are now immediately stopped with StealthWatch. New attacks, for which no signatures exist, now fail to gain a foothold unlike before.”

According to Jeffords,“Most impressive is StealthWatch’s automatic blocking capability. Recently StealthWatch blocked a compromised Linux server within 90 seconds of generating a burst of outbound traffic. Also, StealthWatch shortens the lengthy, manual incident analysis process from weeks to minutes. By automating the monitoring of traffic and alerting of suspicious behavior, StealthWatch does everything we were doing manually and 90 percent more.”

Recognizing the “ high correlation between traffic patterns and bad activity“ and that “new attack scripts can only be identified via traffic pattern analysis and detection,“Jeffords affirms that StealthWatch has “caught many attacks for which no signatures are and never will be written.“

StealthWatch is the behavior-based component of Dartmouth’s overall security architecture, which includes TippingPoint, Cisco PIX and Juniper firewalls, Packeteer and Aruba wireless switches and host-based firewalls. During evaluation, Jeffords found that “unlike StealthWatch, other competitive solutions’ detection approaches could not scale and required deployment of several hundred devices, which was much too costly.”

In the March 2005 issue of SC Magazine, West Coast Bureau Chief Marcia Savage authored a Dartmouth case study titled “The Traffic Cop: Stopping Bugs in Transit.” In the article, she clearly articulates how StealthWatch helped Dartmouth “streamline and automate” the laborious, manual process of studying network traffic patterns to stop attacks and track down infected machines.
