Toward a Multi-Layer Defence Framework for Securing Near-Real-Time Operations in Open RAN
IEEE Open Journal of the Communications SocietySecuring the near-real-time (near-RT) control operations in Open Radio Access Networks (Open RAN) is increasingly critical, yet remains insufficiently addressed, as new runtime threats target the control loop while the system is operational.
