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 3G, 3GPP, 4G, 5GNR, 6G and ADSL — each entry cross-references back to this page so you can walk the topic in either direction.
