The session initiation protocol (SIP) is among the most popular voice over IP (VoIP) signaling protocols. Like other Internet protocols, deployment in live scenarios showed its vulnerability to flooding attacks. These attacks are very similar to those against TCP protocol but have emerged at the application level of the Internet architecture. In this paper, we present a new approach to protect SIP...
SIP is amongst the most popular Voice over IP signaling protocols. Its deployment in live scenarios showed its vulnerability to flooding attacks. In this paper, we present a SIP flooding attack detection mechanism that dynamically detects SIP flooding attacks and correlates in real time the temporal characteristics of SIP reliable mechanism and the number of received INVITE requests. Experimental...
