3GPP 5G SECURITY ARCHITECTURE

3GPP 5G SECURITY ARCHITECTURE

3GPP defines the overall 5G security architecture, illustrated in Figure above.

This includes many network architectural elements and concepts such as:

Network access security (I)

which is the set of security features that enables user equipment (UE) to authenticate and access services via the network securely, including 3GPP access and non3GPP access, and particularly to protect against attacks on the radio interfaces. In addition, it includes the security context delivery from SN to UE for the access security

Network domain security (II)

which is the set of security features that enables network nodes to securely exchange signalling data and user plane data

User domain security (III),

which is the set of security features that secures the user access to mobile equipment (ME)

Application domain security (IV)

which is the set of security features that enables applications in the user domain and in the provider domain to exchange messages securely

SBA domain security (V)

which is the set of security features regarding SBA. These include the network element registration, discovery and authorization security aspects, and also the protection for the service-based interfaces
Visibility and configurability of security (VI), which is the set of features that enables the user to be
informed whether a security feature is in operation
