摘要：The Internet usage has increased rigorously in the modern scenario; cyber-attack such as DDoS attack is still the mostpowerful attack that disrupts the genuine users from accessing the essential services. In application layer-based DDoS attack, attackeruses other machine instead of using his own IP address to flood the targeted system and disrupts the services, that leads to server failure.Most of the reputed enterprises are converting their networks to SDN (software defined networks) for cost efficiency and networkflexibility, but DDoS is one of the most launched attack on SDN layer. DDoS attack in this type of environment leads to system failure,financial loss, data theft, and performance degradation. In our paper, extensive survey has been made to detect and prevent DDoS basedattack in application layer and SDN based environment. Finally, some of the important solutions are outlined. The solutions areproviding promising results based on various parameters..
