Smart cities are rapidly emerging as the backbone of modern urban development, driven by the integration of cutting-edge technologies such as the Internet of Things (IoT), artificial intelligence (AI), and big data. These technologies enhance operational efficiency, improve public services, and contribute to sustainable development. However, they also introduce significant cybersecurity challenges, as the interconnected nature of smart city infrastructure creates vulnerabilities that can be exploited by malicious actors. From transportation systems and energy grids to healthcare and public safety networks, critical urban infrastructure faces a growing risk of cyberattacks that can disrupt essential services, compromise public safety, and lead to significant financial losses. This paper explores the cybersecurity risks facing smart cities, with an emphasis on safeguarding critical infrastructure through a multi-layered defense strategy. It presents a comprehensive analysis of the most common threats, including ransomware attacks, Distributed Denial of Service (DDoS), data breaches, and unauthorized access to IoT devices. The paper proposes a multi-layered approach to security, encompassing network protection, application security, endpoint hardening, data encryption, and real-time monitoring. Each layer serves as a critical component of a holistic defense model, aiming to mitigate risks and enhance resilience against cyber threats. Furthermore, this research highlights the importance of collaboration between public and private sectors, smart city administrators, and cybersecurity professionals. It discusses the necessity of developing proactive incident response plans and implementing advanced technologies such as AI-powered threat detection and blockchain for secure data management. By adopting a multi-layered security strategy, cities can better protect their urban infrastructure and ensure the continued safe operation of smart technologies.
