A Review on Security Issues in Healthcare Cyber-Physical Systems

Abstract

The rapid advancements in computation methodologies and cloud computing along with the rapid expansion of the Internet of things have resulted in tremendous advancements in Cyber-Physical Systems (CPS) especially in health care systems. The competencies for adaptation of advanced healthcare monitoring systems have been raised. In healthcare industries, today CPS ranges from providing smart feedback systems, automated updating of the patient data digitally, continuous passive monitoring of patients using biosensors, and much more. Cyber-Physical Systems are changing into life-saving decision-making systems. Moreover, CPS has developed an unbreakable bonding with Wireless Sensor Networks abbreviated as WSN. The main motive has been to consolidate the major works in the areas of data privacy and security in CPS and healthcare in the survey. In this paper, researchers’ contributions related to the security of Healthcare CPS have been discussed in general and included the latest updated papers in the domain, later, has extended the focus to Wireless Sensor Networks and the vulnerabilities faced along with their defense as an overview. The concept of Sensor Only Networks, an advancement to WSN based on the security policies has been overviewed.
