Cybersecurity and Privacy in Smart Cities for Citizen Welfare

Abstract

In smart cities, technologies and systems of various types, from manual sensors to data collection devices, cooperate to improve citizens' wellbeing. They take advantage of information technologies and the internet of things (IoT) to increase citizens' welfare through the implementation of services with distinct objectives, like reducing energy consumption and improving transport routes and health services. Due to their functionalities and characteristics, IoT devices work interconnectedly and collect large amounts of data. In this context, cybersecurity and privacy arise as topics of central interest, as security breaches can lead to personal data exposure and service interruptions and malfunctions, thus directly affecting citizens' welfare and the implementation of the Sustainable Development Goals. This chapter discusses how cybersecurity risks affect smart cities' operations and citizens' welfare. It presents some current cybersecurity techniques and how to apply them in the smart city context. It also reviews some open issues and future directions.

Engineering the application of machine learning in an IDS based on IoT traffic flow

“…Currently, the use of IoT devices and cyberenabled resources in machine-to-machine and human-to-machine interactions generate large amounts of data (Berman et al, 2019), including confidential, private, and high-value data. Also, in smart cities, IoT devices support a myriad of interconnected services, which increases the risk of cyberattacks (Figueiredo et al, 2022). Cybersecurity systems can be used together with machine learning to take advantage of its characteristics to develop increasingly robust attack detection methods and solutions.…”

“…In the last decade, cities started to provide a wide range of information to their citizens based on IoT data, including car parking availability, transportation routes or schedules, traffic congestion. Also, they started to use IoT devices in critical services, like environmental disasters detection, energy and water supply management, and street surveillance, among others (Figueiredo et al, 2022). Smart cities became one of the major drivers for the IoT applications (Singh et al, 2020).…”

“…The Internet of Things (IoT) paradigm is one of the drivers for a new generation of communication networks, combining a wide variety of hardware and software that provide customers easy-to-use experience and low-cost solutions. IoT devices are present in our cities, homes, industry, healthcare facilities, vehicles, and personal gadgets and can perform several critical tasks and make our lives more comfortable (Figueiredo et al, 2022, Tewari & Gupta, 2017. IoT networks are made up of a large number of devices and sensors that collect and share large volumes of data, including confidential and private ones (Neisse et al, 2014, Tewari & Gupta, 2020.…”

“…The use of IoT devices has also boosted the creation of smart environments, such as smart cities. In these contexts, they provide a wide variety of services, increasing the well-being of the population and the conscious use of resources (Figueiredo et al, 2022).…”

Cybersecurity and Cyber Forensics for Smart Cities: A Comprehensive Literature Review and Survey

“…Ma [ 57 ] provided functional solutions for maintaining both user privacy and security in smart cities and also explained relevant cybersecurity threats. Figueiredo et al [ 58 ] discussed the cybersecurity issues and risks in smart city operations. They also presented the current cybersecurity techniques and their applications and discussed possible future directions for smart cities.…”
