Evaluating risk scenarios and assessing current controls is the most helpful in identifying gaps between the current and desired state of the IT risk environment, because it allows the risk practitioner to compare the actual and expected outcomes of the IT processes and activities under different situations. A risk scenario is a hypothetical situation that describes a possible event or sequence of events that may affect the IT objectives and performance. A risk scenario can be based on various factors, such as the sources of risk, the risk drivers, the risk events, the risk impacts, and the risk responses. A risk scenario can also include the likelihood and severity of the risk, as well as the assumptions and uncertainties involved. Evaluating risk scenarios helps the risk practitioner to understand the nature and extent of the IT risks, as well as the potential consequences and opportunities that may arise from them. Assessing current controls is the process of examining and testing the existing controls that are implemented to manage the IT risks. A control is a measure or action that reduces the likelihood or impact of a risk, or enhances the benefits or opportunities of a risk. Assessing current controls helps the risk practitioner to determine the effectiveness and efficiency of the controls, as well as their alignment with the IT objectives and requirements. By evaluating risk scenarios and assessing current controls, the risk practitioner can identify the gaps between the current and desired state of the IT risk environment. The gaps can be related to the following aspects: - The IT objectives and performance: The gaps can indicate the difference between the actual and expected results of theIT processes and activities, as well as the deviation from the IT goals and targets. - The IT risk exposure and appetite: The gaps can indicate the difference between the actualand acceptable level of risk that the organization faces or is willing to take in pursuit of the IT objectives. - The IT risk management process and practices: The gaps can indicate the difference between the actual and expected performance of the IT risk management process, as well as the compliance with the IT risk management policies and standards. - The IT risk culture and awareness: The gaps can indicate the difference between the actual and desired level of risk awareness,understanding, and communication among the IT stakeholders, as well as the alignment with the organizational values and culture. Identifying the gaps between the current and desired state of the IT risk environment is important for the risk practitioner, as it can help to prioritize and address the IT risks, as well as to improve and optimize the IT risk management process and practices. References = Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.3: Risk Scenarios, pp. 63-681
