AP (Access Point)

A networking device allowing wireless devices (Wi-Fi, cellular) to connect to a wired network. In enterprise and carrier environments, APs include security features like WPA2/WPA3 encryption and 802.1X authentication.

AP in context

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

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

To place AP in the wider telecom-security picture, review HTTPS, MAC, MACsec, EAP, NAC and Private 5G.
