Management Solutions for Cyber-Physical Security in Smart Built Environment

Cybersecurity risks, together with the associated physical security risks, are hindering the advancement of smart building innovations and applications. The cyber-physical (CP) security for smart built environments is an emerging, critical challenge that cannot be addressed solely by existing cybersecurity means nor traditional physical security means. Currently, because of rapid developments in smart building-related technologies, such as the Internet of Things (IoT), Cyberphysical Systems, and Artificial Intelligence (AI), researchers and industry professionals need a state-of-the-art overview of the solutions for CP security threats in smart built environments. Through a systematic literature review, this paper summarizes and discusses existing management means and methods to achieve more secured built environments. The content analysis results show that most research studies are in the area of smart grids and power systems' CP security, with focuses such as intrusion detection, cyberattack impact mitigation, system status monitoring, and system resilience improvement. The existing gaps of built-environment CP security research include human factors, coordinated attacks, preventive solutions, and the interactions between cybersecurity and physical security.
