(4 pts) Consider a computer in a hospital that controls the radiation dosage, exposure time, and bed movement for a CT scan machine. It receives input from the hospitals network in the form of a record containing a patient number and settings for the scan. Then it sends signals to the hardware to perform the scan according to those settings.

List Confidentiality, Integrity, and Availability requirements for the data and services that such a machine is responsible for.

For each of the requirements, indicate the degree of seriousness (high/medium/low) if the requirement is broken. Justify your answer.
