Policy based virtualised security architecture for SDN/NFV enabled 5G access networks

The challenging traits of 5G networks to support novel and diverse business requirements of vertical sectors have rendered current network security approaches impotent. To address various security requirements of 5G networks and services, a holistic and robust security architecture mindful of 5G technical and business features becomes vital. This paper describes a holistic security architecture for a multi-tenant NFV/SDN enabled 5G access network based on policy-based security management and monitoring & smart analytics.
