Mr. Cusimano’s presentation will address the often-overlooked, systemic vulnerabilities of Packaged Control Systems (PCS)—pre-engineered, plug-and-play units (such as gas compression skids and boiler control systems) that are a mainstay in industrial environments. While PCS offer benefits like rapid deployment and cost-efficiency, they are frequently the most vulnerable components in an OT network.
