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, transport and application delivery. Route hijacks and DNS abuse can degrade or intercept signaling as easily as any application-layer attack, 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, long field lifetimes and limited patchability into operator networks. The same signaling attacks that target smartphones (location tracking, denial of service, credential exfiltration) apply, often at greater scale.

To place Endpoint in the wider telecom-security picture, review Demarcation Point (Demarc), PEI, 5G, Network Slicing, 3GPP and A5/2.
