Implementation of a VoIP simulation network by using stochastic process methods

Abstract

It is not an entirely trivial matter to ensure the security of VoIP services and analyze attacks on telecommunication solutions the possible gains of which are attracting a growing number of active attackers. In many situations, it is necessary to detect and analyze these attacks, monitor their progress and then prepare an effective defence against them. The best way how to detect attacks on VoIP infrastructure is by implementing VoIP honeypot. To attract the highest number of attackers possible, our VoIP honeypots create fake VoIP traffic among themselves. This feature is based on a Markov chains principle. In this paper, we provide a complete implementation of a SIP emulation model which ensures the exchange process of SIP signaling messages between the honeypots.
