Researchers with the Defense Advanced Research Projects Agency (DARPA) have quickly moved to alter the way the military, public and private enterprises protect their networks from high-and low-speed distributed denial-of-service attacks with a program called Extreme DDoS Defense (XD3).
The agency has since September awarded seven XD3 multi-million contracts to Georgia Tech, George Mason University, Invincea Labs, Raytheon BBN, Vencore Labs (two contracts) and this week to the University of Pennsylvania to radically alter DDOS defenses. One more contract is expected under the program.
The UPenn project is developing defenses against distributed denial of service attacks that target specific protocols and their logic. These attacks are often difficult to diagnose and stop because the total volume of malicious traffic may be very low. The UPenn project attempts to pinpoint the specific protocol component that is under attack and then massively replicate that component to blunt the effects of the attack, DARPA stated.
