WOODLAND, Calif.--(BUSINESS WIRE)--Aug. 14, 2001

Network Security Executive's Aug. 21 Presentation Will Explore the

"Code Red" Worm and Other Devastating Internet Disruptions

-- and Their Countermeasures

Captus Networks, the leader in protecting networks from Denial of Service (DoS) attacks, today announced that its president and CEO Richard G. Helgeson will explore the state-of-the-art in DoS countermeasures in a session presentation at the Web Hosting Expo, which runs Aug. 20-22 at the Marriott Wardman Park Hotel in Washington, D.C. In discussing "The DoS Threat: How to Protect Your Company, Customers, and Service Level Agreements," Helgeson will examine the growing sophistication of DoS attacks -- including last month's "Code Red" worm which caused Internet service disruptions worldwide -- and will delineate strategies that companies and service providers can implement to stop them immediately.

Helgeson's 50-minute presentation will begin at 10 a.m., Tuesday, Aug. 21, in the Coolidge Room at the Marriott Wardman Park Hotel.

"I'm looking forward to the opportunity to address a select group of network security managers at Web Hosting Expo on the critical issue of defending against DoS attacks," Helgeson said. "The Web is now under continual siege by hackers. As a result, network security has become more urgent and challenging than ever before. Fortunately, there are technologies and strategies that security administrators can deploy to stop DoS attacks before they disrupt service to legitimate users."

In his presentation, Helgeson will discuss how to identify network vulnerabilities, take the measures necessary to secure a network, and evaluate the capabilities of products for countering DoS attacks available on the market today.
