Major Challenges and Concerns of Internet of Things (Iot) Security in Critical Healthcare

In an IoT space, everyday objects are equipped with microprocessors for data acquisition, transceivers to enable them to sense the surroundings and transfer with each other over the Internet. In this environment, intelligent objects can communicate with one another forming a promising model to offer services that can be accessible to anyone, anywhere, anytime. It has been widely accepted that our daily lives will be fundamentally enriched with various IoT services in healthcare domain. The inherent nature of the Internet of Things technology makes it an indispensable choice for patient monitoring in critical care areas. Along with the incredible opportunities provided by IoT, it also opens new risks and threats. As more and more medical devices are interconnected, they are increasingly exposed to security risks, malware, and user’s privacy. The rise in new attack vectors and poorly configured device settings may become a potential target for hackers to compromise affecting the resilience of the medical devices Hackers & targeted attacks could not only impair the medical devices functionality but potentially adversely effect on patient safety. The paper presents on the impact of security across IoT objects. and discusses how authentication, authorization, availability, confidentiality, integrity, and non-repudiation and privacy plays a critical role in the success of IoT.
