A New Architecture to Protect SIP Server against Flooding Attack

Mourade Azrour, Mohammed Ouanan, Yousef Farhaoui


Session Initiation Protocol (SIP) is coming the most popular used signaling protocol by the Telephony over IP (ToIP) to open, alter, and terminate a multimedia session among various participants. As result of this popularity SIP become new targets of several attacks. Flooding attack is one of those attacks, which is applied to consume server’s resources; in this attack a malicious try to flood its victim with a lot of messages more than it can process in a giving period time. In this paper we propose a new architecture that can protect SIP servers against flooding attack. Our proposed architecture is implemented under JAVA programming language. Then, we have done the experimental tests in Local Area Network, the obtained results prove that the proposed architecture can detect flooding attack as well as it can provide the service even if the attack is detected.
