The primary input when designing IT controls should be internal and external risk reports. IT controls are specific activities performed by persons or systems to ensure that business objectives are met, and thatthe confidentiality, integrity, and availability of data and the overall management of the IT function are ensured1. Designing IT controls means creating and implementing the appropriate measures or actions to reduce the likelihood or impact of the IT risks that may affect the organization2. Internal and external risk reports are documents that provide information and analysis on the current and potential IT risks that the organization faces, as well as their sources, drivers, consequences, and responses3. Internal risk reports are generated by the organization itself, such as by the IT risk management function, the internal audit function, or the business units. External risk reports are obtained from external sources, such as regulators, industry associations, or third-party service providers. Internal and external risk reports are the primary input when designing IT controls, because they help to:
Identify and prioritize the IT risks that need to be addressed by the IT controls; Evaluate the likelihood and impact of the IT risks, and compare them against the organization's risk appetite and tolerance; Determine the most suitable and effective IT control objectives and activities to mitigate the IT risks; Align the IT control design and implementation with the organization's objectives, strategies, and values; Monitor and measure the performance and effectiveness of the IT controls in reducing the IT risks. The other options are not the primary input when designing IT controls, as they are either less relevant or less specific than internal and external risk reports. Benchmark of industry standards is a comparison of the organization's IT control practices and performance with those of other organizations in the same industry or sector4.
Benchmark of industry standards can help to improve the quality and consistency of the IT control design and implementation, as well as to identify the best practices and gaps. However, benchmark of industry standards is not the primary input when designing IT controls, as it does not address the specific IT risks that the organization faces, or the IT control objectives and activities that are appropriate and effective for the organization. Recommendations from IT risk experts are the suggestions or advice from the professionals or specialists who have the knowledge and experience in IT risk management and IT control design and implementation5. Recommendations from IT risk experts can help to enhance the IT control design and implementation, as well as to provide guidance and support to the organization. However, recommendations from IT risk experts are not the primary input when designing IT controls, as they are based on the opinions and perceptions of the experts, and may not reflect the actual or objective level and nature of the IT risks, or the IT control objectives and activities that are suitable and efficient for the organization. Outcome of control self-assessments is the result or conclusion of the evaluation and testing of the design and operation of the existing IT controls by the organization itself, such as by the IT control owners, the IT risk management function, or the business units6. Outcome of control self-assessments can help to improve the IT control design and implementation, as well as to detect and correct any issues or deficiencies. However, outcome of control self-assessments is not the primary input when designing IT controls, as it does not cover the new or emerging IT risks that the organization may face, or the IT control objectives and activities that are relevant and necessary for the organization.

The most effective approach to prioritize risk scenarios is by assessing the impact to the strategic plan, because this will help to align the risk management process with the organization's vision, mission, and goals.
The strategic plan is the document that defines the organization's direction, priorities, and objectives, and guides the allocation of resources and efforts. By assessing the impact to the strategic plan, the organization can determine which risk scenarios pose the greatest threat or opportunity to the achievement of the strategic objectives, and prioritize them accordingly. The other options are not as effective as assessing the impact to the strategic plan, because they do not directly relate to the organization's specific context, needs, and expectations, as explained below:
B: Aligning with industry best practices is an approach that involves following the standards, norms, and expectations for risk management that are established and followed by the peers or competitors in the same industry or sector. Aligning with industry best practices can help to benchmark and compare the organization' s risk management performance and maturity, and identify areas for improvement or innovation. However, this approach is not as effective as assessing the impact to the strategic plan, because it does not account for the organization's unique and customized risk scenarios, which may differ from the industry average or standard.
C: Soliciting input from risk management experts is an approach that involves seeking advice, guidance, or feedback from the professionals or specialists who have the knowledge, experience, or skills in risk management. Soliciting input from risk management experts can help to enhance the quality and validity of the risk analysis and evaluation, and provide insights and recommendations for risk mitigation. However, this approach is not as effective as assessing the impact to the strategic plan, because it does not reflect the organization's risk appetite, preferences, and expectations, which may differ from the risk management experts' opinions or perspectives.
D: Evaluating the cost of risk response is an approach that involves estimating the resources and efforts required to implement the risk response strategies, such as avoiding, reducing, transferring, or accepting the risk. Evaluating the cost of risk response can help to optimize the risk management efficiency and effectiveness, and balance the potential benefits and costs of taking risks. However, this approach is not as effective as assessing the impact to the strategic plan, because it does not consider the potential consequences and outcomes of the risk scenarios, which may affect the organization's performance and reputation.

According to the CRISC Review Manual, risk taxonomy is the system of classification and categorization of risks based on common characteristics and attributes. Risk taxonomy is necessary to enable an IT risk register to be consolidated with the rest of the organization's risk register, because it helps to ensure consistency, comparability, and alignment of the risks across the organization. Risk taxonomy also helps to facilitate the communication, reporting, and aggregation of the risks. The other options are not the correct answers, because they are not essential for consolidating the risk registers. Risk response is the action taken to address the risk, which may vary depending on the risk level and strategy. Risk appetite is the amount and type of risk that an organization is willing to accept, which may differ across the organization's units and functions. Risk ranking is the process of prioritizing the risks based on their impact and likelihood, which may change over time and context.

Role-based access controls (RBAC) are a type of preventive control that limit the access and actions of users based on their roles and responsibilities within the organization. RBAC can help to address the risk of malicious outsiders modifying application data by restricting their access to the data and the functions they can perform on it. RBAC can also enforce the principle of least privilege, which means that users only have the minimum level of access required to perform their tasks. RBAC can be implemented through policies, procedures, and technical mechanisms such as access control lists, encryption, and authentication.

Determining the business purpose of the application is the first thing that a risk practitioner should do when a shadow IT application is identified in a business owner's business impact analysis (BIA), because it helps to understand the rationale and value of the application, and the potential risks and issues that it may introduce or affect. A shadow IT application is an IT system or application that is used by the business units or employees without the knowledge or approval of the IT department or management. A shadow IT application may offer benefits such as convenience, efficiency, or innovation, but it may also pose risks such as security breaches, data loss, compatibility issues, or regulatory non-compliance. A BIA is a process of analyzing the potential impact of disruption to the critical business functions or processes, and identifying the recovery priorities and requirements. A BIA may reveal the existence of a shadow IT application, as it may be used to support or enable a critical business function or process. Determining the business purpose of the application is the first thing to do, as it helps to evaluate the necessity and suitability of the application, and to plan the appropriate actions to address the shadow IT application. Including the application in the business continuity plan (BCP), segregating the application from the network, and reporting the finding to management are all possible things to do after determining the business purpose of the application, but they are not the first thing to do, as they depend on the results of the evaluation of the application.
