Abstract
DDoS(Distributed Denial of Service) attack is a critical threat to current Internet. Recently too many technologies of the detection and prevention have developed, but it is difficult that the IDS distinguishes normal traffic from the DDoS attack. Therefore, when the DDoS attack is detected by IDS, the firewall just discards all over-bounded traffic for a victim of absolutely decreases the threshold of the router. Also, Attacker use spoofing IP address. To solve this problem, we propose security framework using IP Traceback being able to response DDoS attack. Our Implementation shows that proposed security framework is safe to deploy and protect data in network from attackers and others.
