Cybersecurity of critical infrastructure in smart city

Abstract

The security of the country, its economy, cities, and their citizens depends on the critical infrastructure, which is the most important part of the total infrastructure. Each subsystem within the critical infrastructure system provides services to other subsystems, and in this sense, they are characterized by a large number of interwoven, tight connections. By maliciously acting on one subsystem, a ripple effect is created that can grow so much that it threatens the security of the state itself. Therefore, the cyber security aspects of critical infrastructure are very important for researchers, government agencies, and professional individuals. The vision of a smart city should enable a better life for all its citizens and humanity as a whole. It presupposes the use of 4.0 technologies such as the Internet of Things, cloud computing, big data, and artificial intelligence. In past, critical infrastructure subsystems have relied to a greater or lesser extent on isolated and proprietary technologies. With the introduction of "things" into those subsystems, a new polygon is created that includes a large number of vulnerabilities that did not exist until that moment.This paper attempts to shed light on the cybersecurity aspects of critical infrastructure in smart city scenarios.
