Design and Analytical Validation of a Context-Aware Security Framework for Information-Sharing-Enabled Internet of Medical Things (IoMT) in Healthcare Systems

The integration of Internet of Medical Things (IoMT) technologies has enhanced healthcare delivery through real-time data exchange and interoperable clinical systems. However, this integration simultaneously expanded cybersecurity risks associated with information sharing, especially in resource-constrained healthcare environments such as Nsambya and Rubaga Hospitals, where the research was conducted. This study aimed to design and analytically validate a context-aware security framework for information-sharing-enabled IoMT systems in healthcare. Guided by the Digital Health Security Architecture (DHSA) and Design Science Research (DSR), the study synthesized findings from prior framework evaluations and a comprehensive security requirements analysis to develop a multi-dimensional security framework. The proposed framework integrated four interdependent dimensions—technical security functionalities, compliance and governance mechanisms, IT–clinical alignment, and socio-behavioral moderators—demonstrating full coverage of technical, organizational, behavioral, and contextual security requirements. Analytical and contextual validation indicated that the framework offered a robust, adaptable, and healthcare-oriented solution for securing IoMT-enabled healthcare systems, particularly in resource-constrained settings.
