Hospitals exist to take care of patients, not to write software, so they typically purchase it from third parties. HIPAA covers only health care and insurance providers but not the companies that produce software used in health care.

Let's continue with our hypothetical visit to the hospital to uncover other software vulnerabilities and learn more about the importance
The doctor runs you through a couple of tests to assess your condition. You are attached to a PC where an electrocardiogram is run. Little do you know that the administrative passwords on these PCs are the same at every hospital that uses them. The doctor then accesses your test results over the Internet using a laptop computer. When the doctor leaves, you notice that your results remain on the laptop screen for all to see.
After the EKG, the doctor orders a chest X-ray to take a closer look at your heart. A contracted radiologist in another country reads the image through the Internet via a Web server that accesses your information from the radiology database with a single administrative password sent in clear text. Although the data is SSL encrypted, the vendor doesn't know about Web server hardening or secure Web application development. The server is also several months behind with critical patches because the vendor has not yet authorized them.
The doctor determines you need an operation, but when you are wheeled into the hospital's heart center for the procedure, you are unaware that the software vendor for the hospital is working on the cardiology treatment application. The vendor uses a VPN that's always on, with a single username for all of its support staffers who have administrative access to the database.
