1 Scope p. 8
The present document studies the potential security enhancements for supporting 5G NR Femto. More specifically, the study investigates potential security enhancements in the following areas:
- With the gap analysis, study the potential updates or enhancements needed for 5G NR Femto over TS 33.320.
- Study the security impacts for interworking between CAG and CSG cells.
- Study the security impacts of enabling provisioning of subscribers allowed to access 5G NR Femto cells and how to manage 5G NR Femto access control by the Closed Access Group (CAG) owner or an authorized administrator.

4 Security Architecture and Assumptions p. 9
The following architecture and security assumptions are applied to the present document:
- The architectural assumptions and principles captured in TR 23.700-45 are used as architecture assumptions in this study.
- The security architecture defined in clause 4.1 in TS 33.320 can be reused as basis for this study. Whether all components are all necessary and what are the function names in 5G will be studied in the present document.
