Aviation, tourism, and hospitality confront enormous problems and possibilities in a digital age, with cybersecurity crucial to their success and resilience. This chapter examines the various effects of cybersecurity on these interrelated industries and the potential implications of breaches and vulnerabilities. The aviation industry is concerned about cyber risks to flight systems and air traffic control. In contrast, tourism and hospitality businesses must balance client data privacy with reservation system efficiency. The financial effects of data breaches and fraudulent transactions emphasize regulatory compliance's significance in protecting sensitive data. Interconnected aviation, tourism, and hospitality supply chains provide unique difficulties that require thorough third-party risk management. Cybersecurity plans include risk assessments, personnel training, safe system design, and cybersecurity expert cooperation. For robust cybersecurity in these dynamic and linked industries, continuous monitoring and responsiveness to new threats are needed.
