H-IoT THE METHOD OF DEFENSE AGAINST DISTRIBUTED DENIAL-OF-SERVICE ATTACK ON THE HETEROGENEOUS IOT NETWORK AND THE SYSTEM THEREOF

摘要

The present invention relates to a method for defending a distributed denial of service (DDOS) attack on a heterogeneous internet of things (H-IoT) network, which is capable of efficiently managing the DDOS attack and a system thereof. According to one embodiment of the present invention, the method comprises the steps of: allowing an end-point defender placed at an edge node of an IoT network to receive traffic information from the IoT network; allowing the end-point defender to perform machine learning for the traffic information; allowing the end-point defender to generate a traffic statistic report based on the machine-learned traffic information; allowing an orchestrator to receive the traffic statistic report from the end-point defender to analyze a DDOS attack; allowing the orchestrator to generate and transmit a policy to the end-point defender when the DDOS attack is detected; and allowing the end-point defender to extract traffic features upon the DDOS attack based on the received policy to apply the traffic features to the machine learning.
