Internet congestion existing solutions such as active queue management algorithms have many shortcomings, mainly related to the detection phase. These algorithms depend on routers' buffer statistics to detect congestion and their performance is highly affected by the environment and the parameters that are used. In this paper we are proposing a mechanism(More)
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(More)
SIP is among the most popular Voice over IP signaling protocols. Its deployment in live scenarios showed vulnerability to attacks defined as signaling attacks. These attacks are used to tear down a session or manipulate its parameters. In this paper we present a security mechanism that protects SIP sessions against such attacks. The mechanism uses SIP(More)
