NTN in context

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 NTN in the wider telecom-security picture, review LEO, ZSM, 3GPP, Attack Surface Mapping, Zigbee and 6G: each entry cross-references back to this page so you can walk the topic in either direction.
