Corrent Fights DDoS Attacks

TEMPE, Ariz. -- Corrent Corp., the price/performance leader in network security technology, today announced the release of an upgrade to its S3500 Turbocard Firewall/VPN accelerator that will enable it to withstand a massive Distributed Denial of Service (DDoS) attack, while keeping valid network traffic flowing at a high rate. This new capability, a first for the industry, is the result of the S3500 Turbocard's huge processing capacity. The new Corrent(R) S3500 Turbocard is able to sustain 50,000 TCP sessions per second and deliver 648 Megabits per second in throughput in the face of a concentrated attack. In a typical DDoS attack, hundreds or even thousands of "zombie" computers that have been infected by a worm begin sending requests continuously to a "victim" site. The counterfeit requests quickly overwhelm the security appliance and choke off legitimate traffic, inevitably saturating the firewall and causing it to fail. DDoS attacks, which each year account for billions of dollars in economic damage worldwide, are among the most serious threats to ISPs, eCommerce, eBusiness, and corporate networks. A study by the University of California at San Diego estimates that there are at least 4,000 DDoS attacks each week and the number is growing. Spread by worms such as Code Red and Slammer, the Computer Emergency Response Team (CERT) warns that the hidden programs needed to launch a massive attack can infect thousands of machines and reach global saturation within 18 hours.
