Agent Based Preventive Measure for UDP Flood Attack in DDoS Attacks

摘要

Distributed Denial-of-Service (DDoS) attack is an attack which makes victim resources and services unavailable to its intended users. In particular, User Datagram Protocol (UDP) flood attack in DDoS attacks is a method causing host based denial of service. It occurs when attacker sends UDP packets to a random port on the victim system, causing responses to be sent to forged IP address. The basic thrust of this paper is agent based solution for UDP flood attack because software agent technology seems to be a strong candidate for defending DDoS attacks and very few researchers have thought of deploying agents towards providing solution for UDP attack earlier.
