VoIP (Voice-over-IP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. These include denial - of service attacks, worms, viruses, and hacker exploitation. In addition to these traditional network security and availability concerns, there are also a plethora of new VoIP protocols that have yet to undergo detailed security analysis and scrutiny. The new challenges of VoIP security are session hijacking, abnormal termination, call flooding and spam. History has shown that many other advances and trends in information technology typically outpace the corresponding realistic security requirements that are often tackled only after these technologies have been widely adopted and deployed. In this paper, we describe the technology protects networks against the known VoIP threats, and propose security mechanism for VoIP session management.
