Cyber security in Healthcare is a growing concern. Since it has been a proliferation of IoT devices, data breaches from the healthcare industry are increasing the concern about how cyber security can protect data from connected medical devices. Recent years have seen numerous hacking and IT security incidents. Many healthcare organizations are facing problems to defend their networks from cybercriminals. In the current digital era, the physical world has a cyber-representation. Both the real and virtual worlds are connected in areas, such as informatics and manufacturing. Health 4.0 (H4.0) refers to a group of initiatives aiming to improve medical care for patients, hospitals, researchers, and medical device suppliers. Increasing collaboration in terms of medical equipment, artificial organs, and biosensors is a way to facilitate H4.0. As a result, cyber security budgets have increased, new technology has been purchased, and healthcare organizations are improving at blocking attacks and keeping their networks secure.
