Streaming Service Dos, Ddos Attack Security Research,

Denial of Service(DoS) and Distributed Denial of Service(DDoS) Attacks make great potential hazard on the safety of various applications on the internet. Especially for Streaming Media Service, the attack-effect of DDoS will be enlarged, since the real time capability and the large cost of Streaming Media Service. In this paper, we do research on the crisis of DoS, DDoS Attacks in Streaming Media Service, Analyse the method and potential crisis of DoS, DDoS attacks in Streaming Media Service, according to find the loopholes in RTSP.On the basic research of analyzing attack mode, we design and implement a defense system against the loopholes of streaming media protocol RTSP. This defense system employs a group of distributed streaming media proxies in order to hide the server, which improves the ability against attacks; It also can filter the malicious connections by analyzing the RTSP requests; and the intrude detect system can detect the health of Streaming Media Service and find the potential attack. We use this defense system in a simulation environment to defense kinds of DoS, DDoS attack caused by loophole of RTSP. It is proved that the defense system is effective.
