Threat modeling for mobile health systems

Mobile Health (mHealth) is on the rise and it is likely to reduce costs and improve the quality of healthcare. It tightly intersects with the Internet of Things (IoT) and comes with special challenges in terms of interoperability and security. This paper focuses on security challenges and offers a mitigation solution especially with a focus on authentication and encryption for resource constrained devices. It identifies assets in a prototyped mHealth ecosystem and classifies threats with the STRIDE methodology. Furthermore the paper identifies associated risk levels using DREAD and outlines possible mitigation strategies to provide a reasonable trustworthy environment.
