This high value of IoMT data creates a greater risk of cyber-attack. The average cost of IoMT data is estimated to be 50 times higher than in other sectors. The main motivation for an attack on the IoMT is the value of the data stored within it, for the monitoring and treatment of patients. The heterogeneity makes the system more vulnerable to cyber-attacks.

The probability of cyber-attacks increases in the case of the IoMT because it works on the concept of the IoT, in which devices, protocols, and operating systems all distinctly constitute the heterogeneous environment. Therefore, the IoMT needs to be protected from various types of cyber-attacks. Security, in any system, is a must, as it not only protects the client’s data and information, but also protects the reputation of the organization.

Finally, the paper gives a panoramic view of the current status of research in the field and outlines some future research directions in this area. Furthermore, the paper also explores various security requirements, inherent design challenges, and various security techniques that could make the IoMT more secure and sustainable. This paper presents state-of-the-art techniques for securing IoMT systems, in terms of data transmission, collection, and storage. In this regard, this paper highlights the significance of implementing key security measures, and essential aspects of the IoMT that make it useful for interconnecting various internal and external working domains of healthcare. However, significant inroads have been made by the on-going research, which powers the IoMT applications by incorporating prevalent security measures.

Security is thus a major challenge in these critical systems, one that inhibits their widespread adoption. Even though such pervasive and low-cost sensing devices can bring about enormous changes in the healthcare sector, these are prone to numerous security and privacy issues. This has led to the development of more complex and heterogeneous Internet of Medical Things (IoMT) systems that have their own operating systems and protocols.

The IoT is integrated with medical devices in order to enable better treatment, cost-effective medical solutions, improved patient monitoring, and enhanced personalized healthcare. Recent advances in machine-to-machine (M2M) communications, mini-hardware manufacturing, and micro computing have led to the development of the Internet of Things (IoT).
