NWDAF (Network Data Analytics Function)
In telecom networks, the NWDAF is the 5G Network Function that collects data from other NFs, OAM, and external sources to produce analytics and machine-learning insights, including anomaly detection and behavior profiling. NWDAF outputs can drive policy decisions, slice optimization, and security use cases such as detecting compromised UEs.

NWDAF in context
The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.
To place NWDAF in the wider telecom-security picture, review 5G, 5G SA, 5G NSA, 5G SBA, ACL and AES — each entry cross-references back to this page so you can walk the topic in either direction.
