Smart Grid Information Security

The structure of the smart grid (SG) can be divided into two main parts, SG infrastructure and SG applications. This chapter offers novel insights and comprehensive analysis on the cyber security of the SG to ensure that the SG is highly secure against the cyber‐attack threat for both communication and physical networks, without impacting customer confidence in the utility provider, and without substantially inconveniencing customers. The structure of the SG from the viewpoint of security can be divided into three layers; the power system layer, the information layer, and the communication layer. Smart grids are electric grids with digital information/communication capabilities. Attacks on the SG network can be divided into three categories as follows: attacks on the physical layer, data injection and data integrity attacks, and network‐based attacks. The chapter presents the challenges of building resilience control in the power system and highlights the governmental efforts needed to secure the SG.
