Towards Cyber-Secure and Hazard-Resilient Smart Civil Structures

Abstract

<p>The accelerated growth of urban areas in the last decades has led to an unprecedented increase in the construction of wind-sensitive structures, e.g., long-span bridges, tall buildings, wind turbines, and solar trackers. To effectively control undesired wind- and earthquake-induced responses, a plethora of operational technology and cyber-physical systems have been introduced, including supervisory control and data acquisition systems, programmable logic controllers, and remote terminal units. All these systems are potential targets for cyberattacks and have already been attacked in other sectors, including energy, industry, education, and health. This study analyzes this threat to critical infrastructure, quantifies its potential damage, and develops possible countermeasures and cyber-defenses so the structural engineering community can effectively address this emerging challenge.</p>
