The present document:
- Describes potential security threats and vulnerabilities that are applicable to the enhanced IAB architecture specified in the TS 38.300, TS 38.331, TS 38.321 and TS 38.340.
- Identifies potential security requirements for those potential security threats and vulnerabilities.
- Proposes candidate solutions to ensure that the enhanced IAB architecture specified in the TS 38.300, TS 38.331, TS 38.321 and TS 38.340 does not introduce security vulnerabilities in the 5G system providing a secure connection for the UEs connecting to the NR through IAB node(s).
- Concludes with the solutions that should be included in a future normative phase.

IAB-donor:
A RAN node that has wired transport to the core network and provides wireless access to UEs and wireless backhauling functionality to IAB-nodes.
IAB-node:
A RAN node that provides wireless access to UEs and wirelessly backhauls the access traffic.
Access-node:
An IAB-node serving an access UE.
Parent-node:
An IAB-node that is serving other IAB-nodes
Child-node:
An IAB-node which is served by another Parent-node.
Access-link:
