Summary:The purpose of network traffic characterization is to explore unknown patterns in different types of network communications to help improve many aspects of the network. While many previous studies have explored the characterization of many different networks (e.g., university networks), the power grid network (and other SCADA networks) characterization has not yet been studied. In this paper, we provide a characterization of the power grid network to answer questions like the following: i) how stable is the communication based on configurations?; ii) are there different observable traffic patterns in different vendor equipment?; iii) are there trends in the network traffic?; iv) can information be gathered from the traffic characterization to help secure the power grid network? To address these questions, we have collected power grid network traffic in a live substation for two months and conducted an empirical study to identify network traffic behaviors in the live substation. Our empirical study shows different behaviors between the devices and vendors when they communicate with each other.
