Private 5G

A dedicated 5G wireless network deployed for exclusive use by a specific organization, operating independently of public carrier networks. Private 5G provides enterprises with full control over network configuration, security policies, quality of service, and data sovereignty. Private 5G can be deployed using licensed spectrum (leased from carriers), shared spectrum (e.g., CBRS), or as network slices on public infrastructure. Used extensively in manufacturing, healthcare, logistics, and critical infrastructure.

Private 5G 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.

Cryptography in telecom spans air-interface ciphers (A5/1, A5/3, ZUC, SNOW, NEA/NIA), transport (IPsec, TLS) and identity (AKA, 5G-AKA, EAP-AKA'). Weak or downgradeable ciphers remain a live risk on 2G/3G fallback.

To place Private 5G in the wider telecom-security picture, review Zigbee, AP, PLMN, PSTN, 1G and 5G: each entry cross-references back to this page so you can walk the topic in either direction.
