ABSTRACT

Cybersecurity for the smart grid is essential to ensure the resiliency of the supply and delivery of electrical power. This chapter discusses the functions of encryption and access control in more detail. It also discusses frameworks, standards, and regulations that provide a model for securing the utility environment in the smart grid. The chapter reviews the most widely recognized and referenced security standards for the smart grid, as well as a couple of Industrial Control System (ICS) standards that are relevant to the electric industry. The answers to solving the integrity problems are rooted in the security functions of auditing, authorization, nonrepudiation, and message-signing. The chapter describes the functions in more detail. Confidentiality in the smart grid is needed to protect sensitive information, such that if the data were exposed, the data could have the potential to have a negative consequence on the operation of the system.
