Prospects of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) Techniques for Smart Grid Cyber Defense

Abstract

In the enormous growth of smart grid technology, the integration of 5G architecture network technology offers many advantages such as real-time data processing, improved communication facilities, safe data transfer, improved privacy, and diversified services. Yet, it leads to new cybersecurity problems that need to be addressed to ensure the smooth operation of the smart grid. This chapter outlines an extensive study of state-of-the-art network function virtualization (NFV) and software-defined networking (SDN) cybersecurity techniques in smart grid applications. NFV and SDN are key perceptions in the development of 5G networks, promoting flexibility, scalability, programmability, and centralized control over network resources. NFV, along with SDN, promotes the transformation of telecommunication networks, enabling them more adaptable, scalable, and capable of facilitating the diverse services envisioned in the 5G era, protecting critical energy infrastructure from cyber threats.
