1 Scope p. 8

The scope of the present document is:

To address the network slicing open security issues which are left over from Rel-15, specifically:
- Study security and privacy aspects related to the solution for Network Slice specific access authentication and authorization using a User ID and credentials, different from the 3GPP subscription credentials (e.g. SUPI and credentials used for PLMN access) and that takes place after the primary authentication which is still required between the UE and the 5GS for PLMN access authorization and authentication, developed in the FS-eNS study led by SA2.
- Identify and study the open security issues from R15 Network Slices particularly the aspects such as:
  - Inter-slice security isolation.
  - Slice-specific security in the roaming scenarios.
  - Slice-specific security features that can be offered as part of Network Slice as a Service (NSaaS) (Slice management).
  - Slice-specific security features that can be made visible or monitored in the slice management (Slice management).
- Study the security aspects of architectural solutions in SA2 for the enhanced Network Slicing in R16.
- Study the possible security aspects of the Network Slicing interworking with EPC for Connected and Idle mes.
