TopIntroduction
The integration of the Internet of Things (IoT) into smart cities has become a revolutionary force as urban environments alter with technology breakthroughs. The idea covers an extensive network of interconnected devices, which includes sensors that capture environmental data and edge computing that enables real-time decision-making. According to Market Watch, the IoT security market achieved a value of 3.35 billion in 2022 and is projected to see a Compound Annual Growth Rate (CAGR) of 26.36%. It is anticipated to reach a value of 13.36 billion by 2028. The incidence of malware assaults targeting Internet of Things (IoT) devices had a significant surge of 77% during the initial six months of 2022 (Watch, 2023). Gartner says that almost a quarter of all hacks targeting organization’s would use IoT (Poy, 2023). Statista predicts that the market for endpoint security would exceed $29 billion by 2027 (Poy, 2022).
The Internet of Things (IoT) is a network including interconnected objects that engage in communication and data exchange. Smart cities have widely embraced the IoT. A “smart city” is an advanced metropolis that gathers information via the use of technological means and sensors. City operations are enhanced by the data's application to asset, resource, and service management. It aids in enhancing productivity, minimizing expenses, and elevating the quality of life for inhabitants. The system utilizes IoT-enabled devices, such as interconnected Bluetooth sensors, RFID tags, and meters, to gather data in real-time for further analysis. IoT enabled cities will benefit in many ways such as traffic management, environment safety, disaster management and much more (Ahmed et al., 2021). The scope of IoT in smart cities includes:

Scope of IoT in smart cities
The networks utilized for connecting IoT devices in smart cities frequently exhibit inadequate security measures, rendering them susceptible to hacking and unauthorized intrusion. Metropolitan regions frequently experience interoperability challenges, meaning that the IoT devices and systems in use are typically not specifically intended to function flawlessly with one another. The significance of security issues is increasing due to several factors, such as: cyber security, cloud security, IoT attacks, weak passwords, identity management, compliance, insider threats, and malware.
Further, the rest of the chapter is organized as follows: components of smart city IoT, addressed data security and privacy, security challenges are discussed, strategies to mitigate risk, emerging technologies with case studies, and finally adaptive security measure are discussed followed by a conclusion.
