Industrial Control Systems (ICS) have become a ubiquitous part of modern critical infrastructure. Automatic Tank Gauge (ATG) systems play a role in this infrastructure by monitoring and managing fuel storage tanks, such as those found in everyday gas stations. These systems ensure that fuel levels are accurately tracked, leaks are detected early, and inventory is managed efficiently. Although the typical gas station comes to mind when thinking about fuel tanks, these systems also exist in other critical facilities, including military bases, hospitals, airports, emergency services, and power plants, to name a few.
