Study on enhanced security for network slicing phase 2
The present document identifies key issues, potential security and privacy requirements and solutions with respect to network slicing Phase 2 work TS 23.501 [2], TS 23.502 [3], TS 23.503 [4] and studies TR 23.700-40 [5] and TR 38.832 [6], specifically,
- Define the security requirements and security services for new NF(s) introduced for UEs' network slice access control.
- Study potential security risks/threats (i.e. DoS, sensitive information leakage) and solutions if needed with respect to slice-related quota management, data rate limitation, and constraints on simultaneous use of slices.
- Study potential security risks/threats related to broadcasting slice-related cell selection/reselection info, and provide security solutions if needed.
