Emerging E-health applications utilizing IoT (Internet of Things) solutions should be sufficiently secure and robust. Adaptive security management techniques enable maintenance of sufficient security level during changing context, threats and usage scenarios. Systematic adaptive security management is based on security metrics. We analyze security objective decomposition strategies for an IoT E-health application. These strategies enable development of meaningful security metrics. Adaptive security solutions need security metrics to be able to adapt the relevant security parameters according to contextual and threat changes, which are typical for patient-centric IoT solutions used in various environments. In order to achieve this we have developed a context-aware Markov game theoretic model for security metrics risk impact assessment to measurably evaluate and validate the run-time adaptivity of IoT security solutions.
