Deepa Kunju Krishnan, Swapnil Singh · 2022
Health care IoT industry has witnessed tremendous momentum in recent years due to the widespread availability of high speed internet and multi-functional cost economical sensors of varying sizes ranging even to nano sizes. The medical community and end-users have embraced the potential of IoT in leveraging cost-effective medical care like never before. The adoption of innovative technology has been steadily increasing over the years, be it consumer devices, wearable devices, and in-body devices. However, most device manufacturers overlook the security and privacy aspect of the devices in the rat race to deliver the devices to the market. A successful compromise of a wearable IoT device can further escalate security attacks on other parts of healthcare networks as distributed denial of service attacks. In recent years, few alarming cases have been witnessed where patient safety and the confidentiality of their data was at stake. This underscores the growing necessity of adopting the best security practices in medical IoT. In this chapter, the growing importance of IoT in the medical field and a few important use-cases are reviewed. The recent security attacks targeting smart healthcare and security and privacy concerns are comprehensively analysed. The existing solutions for security and privacy concerns of medical IoT have also been surveyed and a critical review of challenges in existing mechanisms is presented that can open further research in this area.
