Question 9

Sara and Julian need to implement a system for the Johnson Space Flight Center. It is projected that the Center will grow 60% or more over the next two years. These drastic increases at the Center will be reflected in huge increases in personnel, the relocation of offices, and many software upgrades. All of the software to be used in this system is considered "non-secure". The software will be purchased, thus reducing the cost of development.
