Test Name TC_ONLY_UDM_CAN_UPDATE_UDR
Threat Reference

TR 33.926 [5], clause AA.2 Assets and threats specific to the UDR
Requirement Name

Ability of NFs to update UE security-related information in the UDR
Requirement Reference

TS 33.501 [4], clause 5.8b Requirements on the UDR
Requirement Description

Only the UDM is able to update security-related information in the UDR.
Test Purpose
  • Verify that only the UDM is able to update the security related information in the UDR.
Pre-Conditions

  • The test case is applicable if UDR and UDM are implemented as separate network functions (non-colocated)

  • The network environment, such as the UDM, can be simulated.

  • The network environment, such as the non-UDM, can be simulated.
Execution Steps

Test Case 1:

  1. The tester correctly calculates an access token with valid audience and scope claims reflecting the UDM network function to access the UDR resources.

  2. The tester includes the access token into an update request to the UDR, e.g., update the SQN or the Authentication Status.

Test Case 2:

  1. The tester correctly calculates an access token with valid audience and scope claims reflecting a non-UDM network function to access the UDR resources.

  2. The tester includes the access token into an update request to the UDR, e.g., update the SQN or the Authentication Status.
Expected Results

For test case 1: The UDR accepts the service request.

For test case 2: The UDR rejects the service request.
Expected Format of Evidence

Evidence suitable for the interface, e.g., pcap file or screenshot containing the operational results.
