b) The Average Rate of Occurrence (ARO) is 1 per 7 years, derived from the reciprocal of the frequency of the threat category "Crossing project timeline."

a) The single loss expectancy (SLE) of the project is the expected value of the loss that would occur if the project were to be sabotaged. The SLE is calculated by multiplying the estimated value of the project (AV) by the expected frequency (EF) of the sabotage attack.

In the CBA, the AV is given as AED 8,000 and the EF is 15%. Therefore, the SLE is:

SLE = AV * EF = AED 8,000 * 15% = AED 1,200

b) The average rate of occurrence (ARO) of the project is 1 per 7 years. This is calculated by taking the reciprocal of the frequency of occurrence of the threat category "Crossing project timeline", which is listed as 1 per 7 years.

Here is a breakdown of the calculations:

* SLE = AV x EF

* SLE = 8000 AED x 15%

* SLE = 1200 AED

* ARO = 1 / Frequency of Occurrence

* ARO = 1 / 1 per 7 years

* ARO = 1 per 7 years
