Neco 2024 Data Processing Question 21
Practice objective / multiple choice question 21 from the 2024 Neco Data Processing examination.
A small business is evaluating three security controls. Control A (firewall) costs \(\text{₦}150{,}000\) and reduces the overall risk by 60\%. Control B (encryption) costs \(\text{₦}120{,}000\) and reduces risk by 50\%. Control C (IDS) costs \(\text{₦}200{,}000\) and reduces risk by 40\%. The initial risk level is 100 units and risk reductions are multiplicative, i.e. after applying a control the remaining risk = previous risk \(\times (1-\text{reduction})\). The business wants the final risk to be at most 20 units. Which combination of controls meets the target with the minimum total cost? State the total cost and the controls chosen.
