Abstract: Software defined network (SDN) for preventing an attack on a host tracking service and a controller included in the same are disclosed. The SDN comprises a plurality of switches arranged on a data plane of the SDN, and connected to at least one host, and a controller arranged on a control plane of the SDN, configured to control the switches and perform a host tracking service for recognizing location of at least one host connected to the switches. Here, a switch A of the switches receives a packet from a host A connected to the switch A and transmits an address information message of the host A to the controller based on the packet. The controller determines whether or not the host A is a host for performing an attack on the host tracking service, by using the address information message and previous address information of the host.
