DoH (DNS over HTTPS)

DoH in context

Telecom fraud costs operators an estimated $40+ billion per year. Common vectors include International Revenue Share Fraud (IRSF), Wangiri callback scams, SIM box bypass, PBX hacking, subscription fraud and A2P grey routing. Effective defense combines real-time signaling analytics with CDR-side machine learning.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how the specs interlock (for example 3GPP TS 33.501 with GSMA FS.34 for 5G SBA security), is essential for both design and audit work.

To place DoH in the wider telecom-security picture, review DoT, SIM Box, Traffic Pumping, SM-SR, DetNet and 3G.
