5G-NextGen Core (5GC) refers to the new 5G core networkarchitecture developed by 3GPP. This 5G architecture offers great flexibility for managing heterogeneous devices and applications. But the advanced features of this architecture present new requirements and newchallenges in security. This article presents a comprehensive study on thesecurity of 5G network systems. The document begins with the overallarchitecture of 5GC. After the potential attacks that can exist in the 5G.then the security requirements in the 5G and some solutions that can fight against these attacks finally discussion about 5G services.
