ETSI ISG NFV

In telecom networks, the ETSI Industry Specification Group for Network Functions Virtualization defines the architectural framework, MANO components (NFVO, VNFM, VIM), and security guidelines for virtualized network functions. Its specifications underpin the design of virtualized 4G EPC and 5G core deployments.

ETSI ISG NFV 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.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how they interlock, is essential for both design and audit work.

To place ETSI ISG NFV in the wider telecom-security picture, review AES, Conformance Testing, CSPM, EIR, MEC and NESAS — each entry cross-references back to this page so you can walk the topic in either direction.
