1. Strengthening mobile networks: The power of zero trust and DPI in Open RAN

   As Open RAN architectures evolve, so do the security vulnerabilities they face. This article looks at the importance of zero trust architectures (ZTA) for Open RAN, discussing how access control requirements in a multi-vendor, virtualized, cloud-based architecture necessitate stricter access control and security. It examines the role of deep packet inspection (DPI) in ZTA implementations in Open RAN, and how DPI’s analytics are used to establish user identities, context, and continuous adaptive trust for today’s mobile networks.
