Abstract: As the new generation of mobile communication technology, 5G adopts the service-oriented architecture for

the core network, which splits the whole with multiple functions into multiple individuals with independent functions,

making the core network more flexible. While the introduction of new architectures and new technologies facilitates

communication of users, it also brings some new security issues. This article introduces the security risks of 5G core

network element services and corresponding abnormal detection methods, designs a prototype system for detecting

abnormalities of 5G core network function services by traffic yzing and explains the technical routes of each module

in the prototype.
