threat modelling

In your text book, on page 528, I want you to read the case on iNTegrity.  On page 531, there are 4 exercises related to the case.  Your assignment is to submit a Microsoft Word document completing those 4 exercises.  
It will be to your benefit to review the cases presented before page 528.  The author does a good job of giving you some sample work.
