A Taxonomy of Industrial Control Protocols and Networks in the Power Grid

Despite a growing interest in understanding the industrial control networks that monitor our critical infrastructures (such as the power grid), to date, these networks have been analyzed in isolation from each other and treated as monolithic networks without consideration of the differences. In this article, we use five industrial control protocols to showcase the diversity of applications and usage of these systems. We introduce a taxonomy of industrial protocols and a summary of their security challenges.
