Gce Model Questions Vol1 2021 Computer Studies Question 37
Practice objective / multiple choice question 37 from the 2021 Gce Model Questions Vol1 Computer Studies examination.
An organisation faces three threats. Their annual probabilities and monetary impacts are:\n\n- Threat A: probability \(0.02\), impact \(\$200\) k\n- Threat B: probability \(0.05\), impact \(\$150\) k\n- Threat C: probability \(0.10\), impact \(\$100\) k\n\nThree possible security controls are available:\n\n1. Control X reduces the probability of Threat A by 50 % and costs \(\$5\) k.\n2. Control Y reduces the impact of Threat B by 40 % and costs \(\$4\) k.\n3. Control Z reduces the probability of Threat C by 30 % and its impact by 20 % and costs \(\$6\) k.\n\nFor each control, compute the reduction in expected annual loss per \(\$1\) k spent and state which single control gives the greatest reduction.
