The security of civil aviation represents one of the most important aspects of modern global transportation. The increasing number of flights, the development of digital infrastructure, and the growing cyber threats create the need for new approaches to protecting passengers, personnel, and aviation systems. In this context, information technology (IT) plays a crucial role in improving all aspects of security - from physical and operational to communication and cybersecurity. This paper aims to analyze the significance and application of information technologies within the civil aviation security system, with a special focus on the implementation at Belgrade Nikola Tesla Airport. Through methods of analysis, comparison, and case study, the research examines how modern IT systems contribute to incident prevention, faster communication, process automation, and the reduction of human error risks. The results show that the integration of information technologies significantly increases the efficiency and reliability of security systems, while at the same time requiring continuous technological advancement and staff training. It is concluded that information technologies are not merely a technical tool but a strategic resource that ensures the sustainable development and safety of modern civil aviation.
