Prioritizing risk responses helps to balance the costs and benefits of managing IT risk by ensuring that the most significant risks are addressed first and that the resources allocated to risk management are used efficiently and effectively. Evaluating risk based on frequency and probability is a part of risk analysis, not risk response. Considering risk factors that can be quantified is also a part of risk analysis, and it does not necessarily capture all the relevant aspects of risk. Managing the risk by using controls is a possible risk response, but it does not guarantee that the costs and benefits of risk management are balanced, as some controls may be too expensive or ineffective for the level of risk they mitigate.
