Abstract: Significant changes have been taking place in interactive media transmission as traditional circuit-based PSTN is substituted by packet-based networks called next generation networks (NGN) that use internet protocol (IP). NGN is believed to completely restructure the communication systems. Voice over IP (VoIP) with its cost effective deployment has transpired as a paramount instrument for multimedia communication. Session Initiation Protocol (SIP) is currently the most popular application layer protocol used for signalling purposes to control VoIP connections between communicating parties. SIP, being a simple text-based protocol, is pregnable to various security breaches and Distributed Denial of Service (DDoS) attacks happen to be one of the most devastating cyber threats. In this paper, a detailed analysis on detection of DDoS attacks in SIP based VoIP networks is presented. Machine learning evolves as a building block in cyber security solutions with a large number of techniques available to automate the detection of network attacks and make robust and quick network defence systems. Numerous approaches exist in state of the art for identifying anomalous behaviour in VoIP traffic. This paper includes important aspects that need to be taken into account by the professionals when developing cyber security systems for such networks.
