Attacks and Countermeasures in IoT Based Smart Healthcare Applications

Abstract

The perpetual evolution of IoT continues to make cities smart beyond measure with the abundance of data transactions through expansive networks. Healthcare has been a foremost pillar of settlements and has gained particular focus in recent times owing to the pandemic and the deficiencies it has brought to light. There is an exigency to developing smart healthcare systems that make smart cities more intelligent and sustainable. Therefore, this paper aims to present a study of smart healthcare in the context of a smart city, along with recent and relevant research areas and applications. Several applications have been discussed for early disease diagnosis and emergency services with advanced health technologies. It also focuses on security and privacy issues and the challenges posed by technologies such as wearable devices and big healthcare data. This paper briefly reviews some enhanced schemes and recently proposed security mechanisms as countermeasures to various cyber-attacks. Recent references are primarily used to present smart healthcare privacy and security issues. The issues are laid out briefly based on the different architecture layers, various security attacks, and their corresponding proposed solutions along with other facets of smart health such as Wireless Body Area Network (WBAN) and healthcare data.
