ABSTRACT
In smart built environments, people’s lives digitally connect with city services, buildings, infrastructures, and utilities through information and communication technologies (ICTs). Since the ICT applications in the smart built environments are continually increasing and evolving, the potential benefits that the smart built environments can provide are also growing. This chapter discusses the definition of each layer of smart built environments and reviews the literature regarding the cyber-physical risks according to the type. Some studies addressed the cyber-physical security risks from the aspects of risk cognition and information security management (ISM). The AECO industry is advancing towards the smart building paradigm in which IoT devices and networks are used to improve occupants’ comfort, reduce lifecycle costs, and optimize the operation of building systems. Cyber attacks can impact one or multiple smart building cyber security goals, involving confidentiality, authenticity, integrity, authorization, and availability, non-repudiation. The data decentralization of blockchain can effectively prevent the single point of failure and data loss and breach.
