Securing Smart Cities: Implications and Challenges

Smart cities are designed and envisioned as cities augmented with technological capabilities facilitating various types of actuation, sensing, and control of their infrastructure. Countless possible applications include traffic monitoring and control, energy consumption, parking, lighting, building health and automation, waste management and recycling, air quality, noise monitoring, hazard detection, and auditing. Achieving reliability, safety, security, and privacy in such large and complex system-of-systems poses different challenges. As Internet of Things (IoT) systems form the core of smart-city technologies, this chapter focuses on approaches to monitoring the behavior and properties of IoT devices and protocols. Specifically, the chapter introduces the concepts of detection, fingerprinting, identification, and various proposed techniques that can be used to aid in the difficult but crucial task of mapping the IoT scape in a smart-city environment. Moreover, the chapter discusses behavioral monitoring of system components and how to reason about and model the smart-city environment. Finally, the chapter captures future needs and principles related to connecting and federating IoT technologies in smart cities.
