 This paper proposes a framework for designing secure and sustainable internet of medical things, IOMT systems. It identifies the key challenges facing the medical industry and discusses how IOT can help address them. A case study was conducted at a private medical clinic to demonstrate the effectiveness of the proposed framework. The study showed that the implemented IOMT system met the required security and sustainability standards. The study also found that the use of IOMT devices enabled real-time monitoring of patient vital signs, leading to earlier detection of potential complications. This was consistent with previous research on the benefits of IOMT in remote monitoring, early detection of health issues, and improved medical decision-making.
