Penetration testing applied to 5G Core Network

5G Networks are nowadays a widely used technology, rapidly spreading all over the world, due to an effective need of flexibility and scalability of resources and because of the continuous demands of the latter, by the users. This thesis analyses the 5G Core from the security point of view, checking for any kind of vulnerabilities and weaknesses that can be exploited by baleful users. Indeed, it presents first the parsing of each of the available Core singularly; and then the comparison between three open source 5G Core: Open5gs, Free5gs and OpenAirInterface. Looking for similarities, security flaws and everything that can give a reasoning to choose one of these Core with respect to the others. Sure enough, the idea is that, at the end of this analysis we should render an opinion regarding which one of these three is the best in terms of Confidentiality, Integrity and Availability, also providing countermeasures for each of the weaknesses found.
