From Power to Water: Dissecting SCADA Networks Across Different Critical Infrastructures

Abstract

In recent years, there has been an increasing need to understand the SCADA networks that oversee our essential infrastructures. While previous studies have focused on networks in a single sector, few have taken a comparative approach across multiple critical infrastructures. This paper dissects operational SCADA networks of three essential services: power grids, gas distribution, and water treatment systems. Our analysis reveals some distinct and shared behaviors of these networks, shedding light on their operation and network configuration. Our findings challenge some of the previous perceptions about the uniformity of SCADA networks and emphasize the need for specialized approaches tailored to each critical infrastructure. With this research, we pave the way for better network characterization for cybersecurity measures and more robust designs in intrusion detection systems.
