Gce Model Questions Vol1 2025 Computer Studies Question 23
Practice objective / multiple choice question 23 from the 2025 Gce Model Questions Vol1 Computer Studies examination.
An organisation evaluates three security threats. Threat A has a probability of occurrence of 0.02 per year and would cause a loss of $250,000. Threat B has a probability of 0.05 per year and a loss of $120,000. Threat C has a probability of 0.01 per year and a loss of $500,000. The organisation can install a security control that reduces the probability of Threat A by 60\% and the probability of Threat C by 40\%, at an annual cost of $30,000. The control does not affect Threat B. Using the criterion that the expected annual loss reduction must exceed the cost of the control, should the control be implemented? Show your calculations.
