Endpoint

An endpoint is any device that connects to a network and acts as a source or sink of traffic, workstation, server, mobile phone, IoT sensor, IP phone. Endpoints are the most numerous and often the least controlled assets in any environment, making endpoint hygiene (patching, EDR, configuration baselines) one of the highest-leverage security investments.

Endpoint in context

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect. Route hijacks and DNS abuse can degrade or intercept signaling, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

Cellular IoT — NB-IoT, LTE-M and 5G mMTC — brings billions of devices with weak identities and long field lifetimes into operator networks, extending signaling attack surface at scale.

To place Endpoint in the wider telecom-security picture, review Demarcation Point (Demarc), Network Slicing, PEI, SM-SR, 3G and 3GPP — each entry cross-references back to this page so you can walk the topic in either direction.
