A Categorization of Cloud-Based Services and their Security Analysis in the Healthcare Sector

The contribution of cloud-based services in the healthcare environments is a vital issue in the 21st century. In this paper, presenting its benefits and tools in hospitals, clinics as well as diagnostic centers, the already existing applications and services are separated in categories, which basically concern: data storage, computing power, network, PaaS, SaaS, data analytics, business intelligence and project management. Then, some security and risk assessment issues in cloud-based services are analyzed thoroughly together with some case studies. Furthermore, a risk analysis with a comparative diagram between secured and non-secured cloud systems in health is listed. Finally, conclusions with the suggested future work are presented.
