In this thesis, VoIP systems are presented and their relation to security is examined. More specifically, in the first chapters of the thesis we analyze VoIP technologies more generally, the way they are applied in systems and furthermore, the architectures that they depend on. In the next chapters, protocols that apply on VoIP systems are analyzed in detail. Moreover, the most dangerous VoIP attacks and the security mechanisms are presented. Because of the importance of SIP protocol in VoIP systems, the security that offers is described in a more extended way. Finally, in the last chapter of the thesis, problems that rise in VoIP systems are analyzed and a secure solution is suggested along with the solution's architecture.
