There has been a swift rise in the development of smart cities. This evolution has been prompted by the rise in emerging technologies such as edge computing, IoT, data science, and analytics. Combining these technologies has paved the way for new, automated systems for managing and monitoring procedures and industries, resulting in increased efficiency and improved quality of life. While these interconnected services assist in managing the growing population in the urban environments through efficient service delivery and increased operational efficiency, they also increase the risk of adversary threats, security, and privacy challenges to smart cities. This paper presents the holistic view of the security landscape and highlights the security threats, challenges, and risks to the smart city environment.
