Atlanta - October 26, 2004 - AirDefense, the leader in 24x7 wireless local area network (WLAN) security monitoring, today announced it will provide a new WLAN security component for Computer Sciences Corporation's (NYSE: CSC) Managed Security Services offering. The new component will help protect CSC customer enterprises from the threat of security breaches.

With the new component, CSC's Managed Security Services offering provides wireless detection, analysis, protection and correction of potential risks and threats to the enterprise. Customers also have access to a broad set of services including system installation and integration, site surveys, policy definition and vulnerability assessments.

"For many of our managed services customers, these types of solutions are the key to managing security for business-critical wireless assets," said Chris Steinbach vice president of CSC's Global Security Solutions organization. "We are pleased to work with AirDefense to offer solutions to hundreds of government agencies and Fortune 500 companies that depend on CSC."

By the end of 2004, more than half of all business mobile PCs will be able to connect to WLANs, according to findings from industry analyst firm Gartner, Inc. announced at the Gartner IT Security Summit 2004. Furthermore, Gartner estimates 70 percent of successful WLAN attacks will be caused by the misconfiguration of WLAN access points (APs) and client software. Today, wireless networks are becoming more pervasive due to their flexibility and inexpensive deployment costs. With more mobile employees and contractors deploying APs and creating unofficial networks, organizations are beginning to realize the need for wireless security.

"CSC's business expertise spans a range of industries, solutions and geographies," said Anil Khatod, president and CEO of AirDefense. "As the market becomes aware of the benefits provided by wireless networking, and begins deploying these wireless services on an enterprise scale, this offering is uniquely positioned to improve the enterprise infrastructure by providing the services and solutions globally to protect those critical networks."

The AirDefense security and monitoring system is based on patent-pending technology that incorporates distributed sensors with a server appliance. The remote sensors monitor all WLAN activities 24x7 and communicate with the appliance, which correlates and analyzes the data to provide scalable, centralized management of all WLAN deployments by providing rogue detection, policy enforcement, intrusion protection and health monitoring. The AirDefense solution has been deployed in more than 250 distributed enterprise networks worldwide.
