University of Bahrain uses the time-based model to evaluate the security level of its student Information System (SIS). The current security system components as following: Preventive control (P)= 60 Seconds Detective control (D) = 25 Seconds - Corrective control (C) = 40 Seconds University of Bahrain management believes that the security level of the system is low and it must be increased, which require to spend $20,000. The mprovement of the security system has 4 alternatives as following:

. Alternative 1 would increase P by 25 Seconds. Alternative 2 would decrease C by 20 Seconds. Alternative 3 would increase P by 15 Seconds and reduce C by 20 Seconds. Alternative 4, would increase P by 20 Seconds and reduce D by 10 Seconds. Answer the following questions:

1. Does the SIS of University of Bahrain currently secure? And why?

2. Show the Time-based model Alternative 1

3. Show the Time-based model for Alternative 2

4. Show the Time-based model for Alternative 3

5. Show the Time-based model for Alternative 4

6. Since each alternative has the same cost, which do you think would be the most cost-effective choice? And why?

Question University of Balinin uses the time-bound model to evaluate the security level of its student Information System (515) The current security system components as following Preventive control (P) 60 Seconds Detective control (1) 25 Secondi Corrective control (0) - 10 Seconds University of Bahrain management believes that the security level of the system is low and it must be increased, which required to spend 20.000. The improvement of the security system alternatives as following . Alternative I would increase by 25 Seconds Alternative 2 would decrete Cby 20 Seconds Alternative 3 would increase by 15 Seconds and reduce by 20 Seconds Alternative 4, would increase by 20 Seconds and reduce by 10 Seconds Diversity of Nahrain management believes that the security level of the system is low and it must be increme, which repunetop 20,000 Improvement of the security system has alternatives as following Alternative would incre by 25 Seconds Allemative 2 would decree by 20 Seconds Alternative 3 would increase by 15 Seconds and reduce by 20 Seconds Alternative 4, would increase by 20 Seconds and reduce 1) by 10 Seconda Answer the following questions: + Does tho SiS or University of Bahrain currently secure?
