This guidance—created by the Enduring Security Framework (ESF), a public-private cross-sector working group led by the NSA and CISA—presents recommendations to address some identified threats to 5G standalone network slicing, and provides industry recognized practices for the design, deployment, operation, and maintenance of a hardened 5G standalone network slice(s).
For the purposes of this paper, a network slice is defined as an end-to-end logical network that provides specific network capabilities and characteristics for a user. More specifically, it is a network architecture that allows infrastructure providers to divide their network up into several virtual networks to satisfy different 5G use cases with varying quality of service requirements and was not intended to be a security mechanism to isolate different 5G user sets.
5G network slicing is a network architecture that provides a way to divides a network to provide independent logical networks over physical network resources and functionality. This can help operators provide differentiated services and more quickly deploy new cases.
An operator can use network slicing to logically allocate physical resources across one or more slices, where each slice may have a different Quality of Service (QoS) and other performance characteristics, as well as configurations and policies, to meet a variety of use cases and possible Service Level Agreements (SLAs). For example, a slice supporting mobile broadband users requires high data rates and traffic volumes, a slice supporting Internet of Things devices may optimize high-density devices and power consumption, and a slice supporting autonomous driving may provide high-reliability and low-latency communications.
