Um, excuse me. Do you have clearance to patch that MRI scanner?

Computerised medical devices need TWO computers

One computer to handle the medical function networked by an internal link to a firewall/security computer. All control of the medical device is on one computer that runs the approved (and often years out of date) software for the device. The second (firewall) computer as it does not control the device can be kept up to date to deal with evolving security threats. There must be NO external (outside the device) network connection except via the firewall computer. Any USB (or similar) ports on the control computer must be behind locked access panels (or disabled with epoxy glue).
