b. The company is considering investing up to an additional $100,000 to improve its secu- rity. Given the following possibilities, which single investment would you recommend? Which combination of investments would you recommend? Explain your answer. • An investment of $75,000 would change the estimates for protection time to 19 minutes (worst case), 23 minutes (average case), and 30 minutes (best case). An investment of $75,000 would change the estimates for detection time to 2 minutes (best case), 4 minutes (average case), and 7 minutes (worst case). An investment of $75,000 would change the estimates for response time to 3 minutes (best case), 6 minutes (average case), and 10 minutes (worst case). An investment of $25,000 would change the estimates for protection time to 17 minutes (worst case), 22 minutes (average case), and 28 minutes (best case). An investment of $25,000 would change the estimates of detection time to 4 min- utes (best case), 7 minutes (average case) and 9 minutes (worst case). An investment of $25,000 would change the estimates for response time to 4 minutes (best case), 9 minutes (average case), and 12 minutes (worst case).

a. Use the following facts to assess the time-based model of security for the ABC Com-
pany; how well does the existing system protect ABC? Assume that the best-, aver-
age-, and worst-case estimates are independent for each component of the model.
Estimated time that existing controls will protect the system from attack = 15
minutes (worst case), 20 minutes (average case), and 25 minutes (best case)
Estimated time to detect that an attack is happening
minutes (average case) and 10 minutes (worst case)
Estimated time to respond to an attack once it has been detected = 6 minutes
(best case), 14 minutes (average case), and 20 minutes (worst case)
= 5 minutes (best case), 8
