A Survey of Ransomware Attacks for Healthcare Systems: Risks, Challenges, Solutions and Opportunity of Research

Healthcare is one of the most vulnerable sectors of cyber-attacks. As it continues to expand exponentially and moves to digitally-enabled healthcare services, cyber-criminals are trying to take advantage of the weaknesses and security vulnerabilities correlated with these shifts. As a result of technical developments, a multitude of highly powerful risks such as Ransomware is facing the healthcare sector. Ransomware is cyber-attack targeting companies and household users and has increased lately due to its productive results. It conflicts have significantly improved over the last few years. The study shows an exhaustive survey on Ransomware attacks and fixes these attacks. The main aim of this study is to classify the solution strategies for Ransomware attacks in healthcare that used to prevent the Ransomware, such as Blockchain technology, Software define network technology, Machine Learning, and other tools as well as to highlight many issues faced by researchers during the process of discovering a way to solve Ransomware attacks in health care systems. In addition, the study will provide scientific benefits to researchers in the field of information security, health institutions, and security companies.
