Detection and Mitigation of DDOS Attacks By Circular IPS Protection Network

S. Shanthini Priyanka, S. Hasan Hussain

One of the major threat in most of the networks is the distributed denial of service and its mitigation is another important concern, This paper addresses this problem by using the firecol whose core is composed of a ring of Intrusion prevention systems(IPS) defends by exchanging only a selected traffic. In this paper, we address the problem of DDoS attacks and present the theoretical foundation, architecture, and algorithms of the circular protection network. The coreis composed of intrusion prevention systems (IPSs) located at the Internet service providers (ISPs) level. The IPSs form virtual protection rings around the hosts to defend and collaborate by exchanging selected traffic information. The firecol can protect the system even if more than 100GB of messages are sending by the same attacker to the victim. It is a more effective and efficient way to protect the system from the DDOS attack.
