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...
SIP-based Voice Over IP(VoIP) network is becoming predominant in current and future communications. Distributed Denial of service attacks pose a serious threat to VOIP network security. SIP servers are victims of DDos attacks. The major aim of the DDos attacks is to avoid legitimate users to access resources of SIP servers. Distributed Denial of service attacks target the VOIP network by deploying...
A finite state machine contains a finite number of states and produces outputs on state transitions after receiving inputs. Finite state machines are widely used to model systems in diverse areas, including sequential circuits, certain types of programs, and, more recently, communication protocols. The denial of service (DoS) attacks are the hackneyed and evil cyberattacks in the IP which can be easily...
Through deeply analysis of INVITE flooding attack of SIP based VoIP system, a novel VoIP flooding detection scheme called CDVFD (Call Duration based VoIP Flooding Detection) is presented. The CDVFD method makes use of SIP signaling bidirectional interaction, and it can make fast detection using Chi-square value, and can distinguish from normal high VoIP traffic. Experimental results show the effectiveness...
Voice over Internet Protocol (VoIP) is the newest and the fastest growing technology which consists of routing voice conversations over IP-based network. The flexibility of the VoIP system and the convergence of voice and data networks brings with it additional security requirements, VoIP availability is the most important one. Denial-of-service (DoS) attacks are the main concerns with regard to causing...
