Specific to Medical Facilities, Patients Medical Records, Doctor's Visits and notes, that allow Patients to access their Records On Line, this only opened up that Medical Facility to a Computer Server Attack.   As nobody can guarantee that the Computer used by the Patient is 100 percent free of Viruses, Spyware, Malware, Trojan Horses, Ransomware, Rootkit attacks, Redirect Programs, DNS attacks, and lots more, that then infect the Medical Facilities Computers, including all online Diagnostics, Elevators, Critical Life Saving Medical Equipment, Electricity, Heating and Air Conditioning, PBX System, Medical Records, Imaging, Fire Extinguishing System,  and most of the entire Medical Facility, before you even think that they cannot find out that that infection came from YOUR computer, you are WRONG.
