Cyber-physical security presents a unique challenge for smart buildings due to the interconnected nature of cyber and physical systems. Smart buildings rely on a network of sensors, controllers, and actuators, all of which are vulnerable to cyber attacks. A cyber attack can have direct physical consequences, such as manipulating heating systems or access controls, leading to safety and privacy risks. Additionally, the complexity and heterogeneity of these systems make it difficult to secure them against all potential threats. This integration of cyber and physical elements requires a comprehensive approach to security that addresses both aspects simultaneously.
Project 1: Graph-Based Simulation for Cyber-Physical Attacks on Smart Buildings
The research team developed a system called SHSim to simulate cyber-physical attacks on smart buildings. This system models the cyber and physical aspects of a smart building in an integrated graph and simulates various attacks to assess their combined impact. We designed and implemented a prototype of SHSim, and conducted experiments on multiple smart home layouts to demonstrate its functionality and feasibility. The study highlighted the potential vulnerabilities in smart building systems and emphasized the need for comprehensive security solutions that address both cyber and physical threats.
