Its intricate architecture typically encompasses the acquisition of data from a multitude of devices, followed by robust data processing and analysis, culminating in a user interface designed for both healthcare professionals and patients. Key applications span a wide spectrum, from remote patient monitoring and sophisticated wearable health trackers to intelligent hospital systems and the burgeoning field of telemedicine. However, the extensive proliferation of IoMT devices concurrently introduces significant security vulnerabilities, including the critical risks of data breaches, malicious device tampering, and disruptive denial-of-service attacks, thereby necessitating the development and implementation of strong security frameworks and effective privacy-preserving mechanisms. [1] The foundational architecture of IoMT is characterized by distinct layers, including device layers, network layers, and application layers, all working in concert to facilitate seamless healthcare operations. This architecture critically relies on the advanced capabilities of cloud computing and edge computing paradigms for the efficient management and processing of the immense volumes of data generated by these connected medical devices. The article further explores diverse applications, ranging from the management of chronic diseases to sophisticated emergency response systems, strongly underscoring IoMT's profound potential to significantly improve healthcare accessibility and overall efficiency. A paramount aspect discussed is the critical importance of robust cybersecurity measures within IoMT ecosystems, with a specific focus on prevalent threats such as unauthorized access and the compromising of data integrity, alongside the proposal of effective mitigation strategies.
