The report provides a summary of the small cell system security architecture. Driven by the need for cost effective coverage and capacity solution for the evolving data demand, reliance on small cell solution is increasing both indoors and outdoors. The expected mass deployment of small cells largely relies on the providing secure and lawful operation for the user and the core network.
Small cell system has a distinct set of security requirements due to its locations, openness and backhaul implementation. This report outlines the main vulnerability points in the system. It discusses the various possible threats to users, devices and operator’s core network that arise from jeopardizing small cell system security.
Security measures to counteract such threats are explained as well as different roles of network nodes. The report includes a market overview of the current small cell security solution and concludes with an outlook into small cell technologies development and related security aspects.
