Securing 5G Cloud Native NFV Architecture with Zero Trust Security
Taha Sajid · 2023
This study presents a risk-based method to apply zero-trust security concepts to 5G system core networks. It begins by discussing the issues the 5G network has in adopting a typical security strategy and the 3GPP and allied entities' study on NIST's Zero trust tenets. It describes how to identify and prioritize attack vectors, harden the application and infrastructure stack, maintain operational security, and enforce policy decisions across the 5G stack's control and data planes to control and monitor user and machine communication. This study showed promise and will guide enterprises adopting private 5G to leverage their enterprise security controls and maintain zero trust security. It will also provide wireless standard bodies like 3GPP and GSMA with recommendations for the next release
