Background: Global tourism platforms—including online travel agencies (OTAs), hotel booking engines, airline reservation systems, and digital mobility apps—handle vast amounts of personal, financial, and biometric data. As these systems become increasingly interconnected, they are exposed to growing cybersecurity threats ranging from data breaches to ransomware and identity theft.

Objective: This study investigates the cybersecurity risks faced by global tourism platforms, analyzing key vulnerabilities, threat actors, and attack patterns. It also proposes mitigation strategies through technological, organizational, and regulatory frameworks.

Methods: A multi-method approach combining 15 expert interviews, cybersecurity incident analysis (2016–2024), and a survey of 270 tourism platform users was conducted. MITRE ATT&CK, NIST Cybersecurity Framework (CSF), and ISO 27001 were used to categorize risks and mitigation measures.

Results: Findings show that phishing (78%), credential theft (66%), API vulnerabilities (54%), insecure cloud configurations (49%), and DDoS attacks (42%) are the most common cybersecurity risks. Over 70% of surveyed users expressed concern about data misuse. Platforms using multi-factor authentication (MFA), encrypted APIs, and zero-trust architecture reported a 60–75% reduction in cyber incidents.

Conclusion: Tourism platforms face critical cybersecurity challenges due to high data volumes, weak authentication systems, third-party integrations, and inadequate regulatory compliance. Adopting advanced security technologies, continuous monitoring, and global regulatory collaboration is essential for safeguarding digital tourism ecosystems.
