The Internet of Things (IoT) applications are evolving from general applications to precise use cases across various industries, including healthcare, automation, military, maritime, smart cities, transportation, and logistics. In the healthcare sector, IoT-based applications have significantly improved patient assessment, monitoring, and prescription systems with seamless internet-based access. Despite these benefits, IoT applications introduce critical security challenges due to their wireless communication and open-area deployment. Patient wearable devices and other networked entities follow unstructured communication formats, making them highly susceptible to security breaches. Given the critical nature of healthcare data, secure communication infrastructures are essential for data acquisition, processing, storage, and assessment on both client and remote systems. Security remains one of the major obstacles preventing widespread IoT adoption in healthcare. This paper presents a comprehensive review of security constraints in H-IoT, analyzing the unresolved security issues from 2015 to 2023. Based on existing literature, we identify key security requirements and challenges in H-IoT applications and propose future research directions to improve security frameworks for researchers and industry stakeholders.
