Increasing number of vehicles in utilize has conducted in the service to supply human and resource security. The present trend calls for the application of technology to automate safety measures in road traffic and since has been known as Intelligent Transport System (ITS). Vehicular Ad hoc Network is like a fork to Mobile Ad hoc Network, where the nodes are mobile vehicles moving in constrained road topology. VANET networks are visualized to be utilized in practical ITS systems around the world. A network standard has been grown as Wireless Access In Vehicular Environment (IEEE 802.11p) to be utilized in VANET which is an alteration to IEEE 802.11 standard. With each innovative technical applications particularly computers and network appliances, come novel safety challenges. Each network in present time is vulnerable to safety attacks and VANET is not the exception. The most notorious attack among all is the Distributed Denial of Service Attack which is obvious as unlike other safety attacks the data packets utilized in it are genuine and authorized packets. In this paper, a novel offensive measure for detection and prevention has been proposed.
