As people’s needs evolving, so as technology needs to be evolved. Circuit-switched based networks have become obsolete in order to design new technologies that will be faster, always available and easy to use. Such kind of technology is Packet switched network that is based on IP protocol, the protocol of Internet. Thus, networks like 2G or 3G have become obsolete in many countries, whereas 4G or 5G are the main networks for data and voice. VoLTE and VoWiFi are the main voice services of these two technologies which are based on VoIP technology.
The purpose of this thesis is to analyze the vulnerabilities of these 3 voice technologies, VoIP, VoLTE and VoWiFi. We will present a historic background of the circuit and packet switched networks along with their protocols. Moreover, we will proceed to the analysis of their architectural structure and their used protocols, but also proceed to a vulnerability assessment. On the next parts, we will launch some attacks and observe their impact. Finally, we will propose some mitigations that will help to avoid or reduce the impact of such attacks.
