HTTP (Hypertext Transfer Protocol)

HTTP in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

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 HTTP in the wider telecom-security picture, review OAuth2 in 5G Core, Inter-Network Function Authentication, SMPP, HTTP/2 Security in 5G, Network Exposure Function (NEF) and Service-Based Architecture (SBA) Security: each entry cross-references back to this page so you can walk the topic in either direction.
