Abstract
Internet of Medical Things is the internet connection of medical devices to perform services and processes to support the healthcare sector. Wearable Technology in Healthcare has seen tremendous growth in recent times. This is due to a global increase in the aging population, the need for disease management, and effective patient monitoring. The prevalent technology of wearable devices is Bluetooth technology due to its low cost, low energy, and size. Despite the growth recorded in the adoption of Bluetooth Wearable IoMT, there are concerns by users and other healthcare stakeholders about security and privacy issues with its adoption. Our paper presents a simulation of passive and active attacks on 3 wearable IoMT devices, followed by analysis and evaluation of the experiment outcomes. Thereafter, countermeasures for the identified weaknesses were provided. It was discovered that some of the standard security features of Bluetooth Technology to mitigate privacy and security issues were not implemented in some of the devices, which can result in data compromise in the devices. A security assessment framework was developed to assess the security of Bluetooth IoMT devices using the Bayesian Network model. This is used to rank devices, identify their vulnerabilities, and apply security measures on the identified vulnerabilities. Our paper further provides recommendations on improving the security of Bluetooth IoMT devices.

Summary
Internet of Medical Things is the connection of medical devices to the internet to perform services and processes to support the healthcare sector. Wearable Healthcare devices, a branch of Internet of Medical Things, are regarded as one of the fastest-growing markets in recent times. This growth is expected to continue due to increase in device adoption, popularity, functionality, and innovation [1]. There are security concerns about the continued adoption of IoT devices for healthcare, Internet of Medical Things still accounts for one-third of the Internet of Things [2]. This is because patients’ health can be enhanced with IoMT adoption for patient remote monitoring. Muck explains that IoMT devices may be an easy target for attackers to launch a distributed denial-of-service attack on [3]
