On September 22, the Institute for Security Technology Studies at Dartmouth College published a shocking "Predictive Analysis" titled "Cyber Attacks During the War on Terrorism." The 29-page study analyzes relevant historical precedents and makes these conclusions:

-- Cyber attacks accompany physical attacks.

-- Hackers are increasing in volume and sophistication.

-- Cyber Terrorism is a real and immediate threat.

With increasing frequency, networks are being attacked by insidious acts of sabotage, such as the recent Nimda virus and Code Red worm. In order to address the mounting concern of cyber terrorism, WatchGuard Technologies, a leading provider of Internet security solutions, is hosting a Webcast to analyze this threat and discuss practical approaches to protecting network vulnerabilities.

On Thursday, October 18 at 11:00 a.m. PST, join FBI Special Agent Paulynne Schaff of the NIPC Computer Crime Squad, network security experts and West Coast business leaders in analyzing cyber terrorism and practical, effective solutions to potential threats.

"WatchGuard recognizes the need for not only solutions to the threats of cyber terrorism, but also the importance of educating business leaders on vigilantly managing network security," said Chris Slatt, WatchGuard's chairman and CEO. "This Webcast will address the need for IT professionals to discuss the implications of cyber terrorism, as it is a real and potential threat."

The goal of the Webcast is to inform businesses of up-to-date hacking threats, develop a detailed checklist for businesses to assess their level of protection, and offer top-level perspectives on prevailing security issues. Armed with information from the Webcast, business leaders can effectively take steps to protect their networks from the threat of cyber terrorism.
