ABSTRACT
It is estimated that by 2030, more than 60% of the population is going to live in cities. Overpopulation in urban cities causes numerous problems including environmental pollution, emissions exhaustion, global warming, energy waste, health problems, public transport congestion, and overcrowding. Therefore, the transformation of regular cities into smart cities is more vital than ever. Smart cities make usage of intelligent ways to effectively manage various components that are essential to the normal functioning of a city such as transportation systems, the health system, energy and waste infrastructures, residential premises, industrial, commercial and governmental sectors, and the environment to protect the environment, promote sustainability, and improve the life of its citizens. A wide set of complex systems and infrastructures, technologies, social and political mechanisms, the economy, and the citizens are going to play a vital role in its realization, with the most popular being the Internet of Things (IoT). Using the IoT in smart cities allows for the vast collection of data from different and multiple types of sensors from anyone at anytime and from anywhere. This set of data is transferred to the cloud to be processed further and monitor the state of various networks and infrastructures of the smart city and assist its citizens with their lives. However, the presence of the IoT in smart cities brings a whole set of vulnerabilities that when exploited by adversaries can result in not only data theft and network malfunction, but disruptions to the life of its citizens which can be hazardous to them and even cost human lives. In this chapter, we aim to explore the security and privacy issues emerging from the deployment of the IoT in smart cities and its various networks and infrastructures and what solutions could be provided to guard against them.
