Abstract:
The forthcoming 5G mobile networks shall be heterogeneous in nature and embody a large number and variety
of devices. Moreover, Internet of Things applications – like surveillance and maintenance – will use 5G
extensively due to its high availability and quality of connectivity. However, the heterogeneous services,
applications, users, devices, and the large amount of network traffic will bring challenges for the security of
the mobile network. It will be important to provide isolated segments from the network for applications that
require a high level of security. This paper presents the potential of micro-segmenting 5G networks. Micro-segmentation
is a concept that has been considered in data center networking to enforce the security of a data
center by monitoring the flows inside the data center. In this paper we describe how the micro-segmentation
concept could fit into the 5G security architecture and provide scenarios of how software mobile networks can
facilitate securing IoT.
