A. Construct a reliability block diagram for the security system. Is this a series system, parallel system, or mixed system? What are the single point failures? What are the cut sets of size 2 (you must draw the reliability block diagram use Paint, PPT art, or draw/scan)?

B. For each block in the reliability block diagram you created, describe a way in which failure might occur by chance. What can be done to mitigate the chance of failure?

C. For each block in the reliability block diagram you created, describe a way in which failure might occur due to the actions of the threat. What can be done to mitigate the chance of failure from assault?

D. Based on the system as you modeled it, what one thing might you do to improve the effectiveness of the security system?
