Threat Assessment of Wireless Patient Monitoring Systems

We address issues related to threat assessment of mobile patient monitoring systems using a wireless infrastructure including body area biomedical sensor networks. Several user scenarios are presented. Patient sensitive data, mobile and wireless infrastructure, and resource-constraint sensor nodes provide a challenging task of fulfilling some minimum requirements for security, privacy, reliability of the data and availability of the system. We have therefore studied threats associated to both short range and long range mobile wireless communication infrastructures, where requirements for security recommendations for such systems are presented. Emphasis is given on applications that employ a wireless infrastructure, such as biomedical sensor networks. In this work we present an informal threat assessment of mobile patient monitoring systems used with several scenarios.
