Security Analysis of a Patient Monitoring System for the Internet of Things in eHealth

A patient monitoring system for the Internet of Things in eHealth can be established through the integration of wireless body area network, communication infrastructure, and the hospital network. The dynamic and heterogeneous environment of the Internet of Things may facilitate the patient with mobility options. However, security-related problems may obstruct the development of such a comprehensive patient monitoring system. While assessing the security of a patient monitoring system, it is necessary to realise that it may not be enough to only look into the security related aspects of the body area network. Instead, the overall patient monitoring system should be treated as a connected and integrated eHealth system. This paper analyses the important security issues that can put the eHealth system at risk. The specific security goals and requirements, vulnerabilities, threats, and attacks are analysed and some possible security recommendations with direction for future work are discussed.
