Abstract

Voice over IP (VoIP) telephony is becoming widespread in use, and is often integrated into computer networks. Because of this, malicious software threatens VoIP systems in the same way that traditional computer systems have been attacked by viruses, worms, and other automated agents. VoIP networks are a challenge to secure against such malware as much of the network intelligence is focused on the edge devices and access environment. This paper describes the design and implementation of a novel VoIP security architecture in which evaluation of, and mitigation against, malicious traffic is demonstrated by the use of virtual machines to emulate vulnerable clients and servers through the use of apparent attack vectors. This new architecture, which is part of an ongoing research project, establishes interaction between the VoIP backend and the end users, thus providing information about ongoing and unknown attacks to users.
