5G Security Artifacts (DoS / DDoS and Authentication)

5G will deliver a wider broadband access, higher and faster mobility, unprecedented connectivity and coverage to massive matrix of personal devices, mobility based (vehicular! commercial UAVs/ Drones) and Internet of Things / Everything (IoT / IoE) nodes with ensured availability and optimum reliability. Availability is targeted through multipronged Active/Passive attacks using DOS / DDOS (RF jamming / Bandwidth jamming with malformed packets) and reliability is targeted through exploiting existing architectural weaknesses of radio and data communication protocols (LTE-A / IP based Networking). In prevailing threat landscape, concepts of adoption and integration of Software Defined Networking (SDN) and Network Function Virtualization (NFV) in 5G networks will open gateways of new networking paradigms with a focus on centralized security dynamics (overall visibility and substantial controls). These network security dynamics in diversified use cases (Internet of Everything /smart grids) will provide an optimum centralized control with a global overview, vigilant monitoring as well as prompt reaction (detection and prevention) to these prevailing threats. In this purview of the 5G cellular security matrix with a centralized SDN and NFV, this document has reviewed on 5G cellular secure communication channels to unearth the effectiveness of conventional DOS/DDoS and Authentication attacks within environment of SDN and NFV. This research will also present proposed mitigation of DOS / DDOS and incorporation of advanced authentication mechanism for more reliable cellular communication networks.
