This makes travel app security very complicated compared to the security of an ordinary mobile application.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Travel booking platforms often process card details, store passport &amp; ID information, contact details, booking histories, and sometimes even real-time location data. These connections with users to payment gateways, hotels, airline systems, and GDS platforms make them prone to cyber threats. Even the smallest weakness could have serious ramifications such as leaking sensitive data, account takeover, or even fraud.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">How to secure a travel app?

Protection of the travel app data is therefore supposed to be effective and flexible enough to apply to every piece of information.<\/span><\/p>\n<p>\u00a0<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Third-Party_Integrations\"><\/span><b>Third-Party Integrations<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Travel apps are rarely isolated from other systems. They are integrated with payment gateways, airline and hotel APIs, GDS platforms, KYC providers, maps, and customer support systems. If an API is poorly implemented without proper security, it could provide overprivileged access and expose secrets, leading to major security breaches that could exist beyond the application\u2019s source code. This makes travel app cybersecurity truly dependent on the security of the APIs and other third-party ecosystems.<\/span><\/p>\n<p>\u00a0<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Compromised_Accounts\"><\/span><b>Compromised Accounts\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Cybercriminals don\u2019t need to access a full database. A stolen account or API credentials can be used to quickly modify bookings, steal points, obtain access to personal information, or divert payment-related information. So, it\u2019s vital to know how to secure a travel app. This includes protecting data on the mobile client, backend, APIs, integrations, and user accounts. Startups working with a travel app development company often gain this upper hand with knowledge of architectural requirements from the first sprint.<\/span><\/p>\n<p>\u00a0<\/p>\n<p style=\"text-align: center;\"><b>Insight\u00a0<\/b><\/p>\n<p style=\"text-align: center;\"><span style=\"font-weight: 400;\">According to the <\/span><a href=\"https:\/\/www.oecd.org\/en\/publications\/economic-outlook-for-southeast-asia-china-and-india\/volume-2023\/issue-1_f677c529-en\/full-report\/component-5.html\" target=\"_blank\" rel=\"nofollow noopener\"><span style=\"font-weight: 400;\">OECD<\/span><\/a><span style=\"font-weight: 400;\">, hotels are prime targets for cyberattacks because they collect large amounts of personal and financial information, while airlines are also attractive targets because they rely heavily on digital systems.\u00a0<\/span><\/p>\n<p>\u00a0<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Common_Security_Threats_Facing_Travel_Apps\"><\/span><span style=\"text-decoration: underline;\"><b>Common Security Threats Facing Travel Apps<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">There are many threats that can cause harm to travel applications as they work around personal information, money transfers, location-based services, and interactions with third parties.

PCI DSS 4.0 highlights the aspects of access control, authentication, vulnerability management, logging, monitoring, and periodic security assessments. Encrypting the cardholder information alone would not be enough, as we have to minimize its exposure.<\/span><\/p>\n<p>\u00a0<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"2_Use_Tokenization_Instead_of_Storing_Card_Data\"><\/span><b>2.
