Industries are being revolutionised as the Internet of Things (IoT) builds seamless interconnectivity between devices, sensors, and systems like never before. However, the proliferation of IoT also poses numerous security challenges as well, especially in healthcare where patient data can be readily exploited. In this thesis, general IoT is explored first, because the situation of IoT security tends to be quite serious due to the availability issue and heterogeneous or resource-constrained nature and distributed nature of IoT devices. Healthcare is an obvious and most significant area to really concern about the IoT systems security, as it involves very sensitive medical data and life-critical services. To overcome these issues, reference architectures provide a set of guidance to help in the design of secure, scalable, and interoperable IoT systems. This research offers a reference architecture designed specifically for healthcare IoT environments which includes cutting-edge security mechanisms such as encryption, intrusion detection, multi-factor authentication, and role-based access control. The architecture aims to protect data integrity, confidentiality and availability whilst ensuring the performance and usability of the system by following these security principles. This design pattern is a robust solution to protect healthcare IoT systems and comply with industry regulations while mitigating the associated risks with evolving cyber threats.
