Improving security controls is an example of risk mitigation, which is the process of reducing the likelihood or impact of a risk. Risk mitigation can be achieved by implementing various strategies, such as purchasing insurance, discontinuing the activity associated with the risk, or improving security controls. Purchasing insurance is a form of risk transfer, which is the process of shifting the responsibility or burden of a risk to another party. Discontinuing the activity associated with the risk is a form of risk avoidance, which is the process of eliminating or avoiding a potential source of harm. Performing a cost-benefit analysis is a form of risk evaluation, which is the process of assessing the costs and benefits of different options to manage a risk. References = CISM Review Manual, 16th Edition, page 1741; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 802
