A VIVACIOUS APPROACH TO DETECT AND PREVENT DDOS ATTACK

Kharat J.S, Radhakrishna Naik

Abstract: A serious problem on the Internet nowadays is Distributed Denial of Service (DDoS) attacks and this is coordinated attack performed by hackers to immobilize a particular Computer service through manipulation of techniques those are used to provide the Services. In this attack, normally attackers generate a huge amount of requests to victims through compromised computers. DDoS attacks are a critical threat to the internet. Packet flooding DDoS attack is a very common way to attack a victim machine by sending large amount of unwanted traffic. This paper proposes a threshold based approach to detect and prevent the DDoS attack before reaching the victim end with high detection rate and low false positive rate to achieve high performance. The result obtained from various experiments on UDP Flood attack and HTTP GET attack show the effectiveness and the efficiency of our approach

Keywords: Denial of Service (DoS), Distributed Denial of Service (DDoS), Entropy, flooding attack.
