  Smart Grid is a power grid system that uses digital communication
technologies. By deploying intelligent devices throughout the power grid
infrastructure,from power generation to consumption, and enabling communication
among them, it revolutionizes the modern power grid industry with increased
efficiency, reliability, and availability. However, reliance on information and
communication technologies has also made the smart grids exposed to new
vulnerabilities and complications that may negatively impact the availability
and stability of electricity services, which are vital for people's daily
lives. The purpose of this monograph is to provide an up-to-date and
comprehensive survey and tutorial on the cybersecurity aspect of smart grids.
The book focuses on the sources of the cybersecurity issues, the taxonomy of
threats, and the survey of various approaches to overcome or mitigate such
threats. It covers the state-of-the-art research results in recent years, along
with remaining open challenges. We hope that this monograph can be used both as
learning materials for beginners who are embarking on research in this area and
as a useful reference for established researchers in this field.
