Detection and Prevention Of DDoS Attack In software Defined Network
Keywords:
DDoS, SDN, Distributed system, IDSAbstract
Software Defined Network (SDN) is new upcoming field in networking domain which has potential to change the current
networking concepts. It has changed the current network architecture in terms of operation and network deployment. In SDN, the data
and control planes are made separate giving network administrator to design and implement their own concept for network control.
The controller is core part of SDN network as it manages the whole network centrally. It basically controls the incoming
packets and their forwarding route. However the controller are vulnerable to flooding attacks. Because of natural
feature of centralised control these become the potential target. The attackers attack by sending continues spoofed
packets leading to bandwidth occupation and overloading the flow tables in the switch.
To overcome such attack we are using IP based filtering in particular time frame in order to Detect and Prevent DDoS
attack.
