Hospitality organizations rely on Property Management Systems (PMS) for daily tasks, planning, and record keeping. As the operations hub, the PMS interfaces with several services and components within a hotel’s IT system, such as Point-of-Sale (POS) systems, door locks, Wi-Fi networks, and other guest service applications. Adding to the complexity of the network, external business partners’ components and services are also typically connected to the PMS, such as on-premises spas or restaurants, online travel agents, and customer relationship management partners or applications (on-premises or cloud-based). The numerous connections to and users of the PMS could provide a broader surface for attack by malicious actors. Improving the security of the PMS can help protect the business from network intrusions that might lead to data breaches and fraud.
Based on industry research and in collaboration with hospitality industry stakeholders, the NCCoE is proposing a solution to better secure the PMS and its connections within a hotel’s IT system that implements layers of security: point-to-point encryption, data tokenization, multifactor authentication for remote and partner access, network and user behavior analytics, and business-only usage restrictions.
Building on this collaboration with the hospitality business community and vendors of cybersecurity solutions, the NCCoE will explore methods to strengthen the security of the PMS and its connections and will develop an example implementation composed of open-source and commercially available components. This project will produce a NIST Cybersecurity Practice Guide—a publicly available description of the solution and practical steps needed to effectively secure the PMS and its many connections within the hotel IT system.
