In the era of smart cities, Intelligent Transportation Systems (ITS) play a crucial role in enhancing urban mobility, safety, and efficiency. However, as ITS becomes more interconnected and reliant on digital technology, it faces increasing cybersecurity threats. This chapter explores these challenges, starting with the ITS architecture, including connected vehicles, traffic management centers, communication networks, and data platforms. IoT integration and real-time data dependence introduce unique vulnerabilities, opening risks to ransomware, data breaches, denial-of-service attacks, and sensor tampering. Consequences of such attacks range from traffic disruption and accidents to data loss and decreased public trust. To address these issues, we propose a cybersecurity framework for ITS that encompasses risk assessment, threat detection, incident response, and ongoing monitoring, enhanced by AI and machine learning.
