In addition to the risk register, which is a tool to document and monitor the risks that affect the organization, a risk practitioner should review the business objectives of the organization to develop an understanding of its risk profile. The risk profile is a description of the set of risks that the organization faces in relation to its goals and strategies. By reviewing the business objectives, the risk practitioner can identify the sources, drivers, and consequences of the risks, as well as the alignment, prioritization, and tolerance of the risks. The business objectives also provide the context and criteria for evaluating and managing the risks. The other options are not the best choices to review for developing an understanding of the organization's risk profile, as they do not capture the full scope and nature of the risks. The control catalog is a list of the existing controls that are implemented to mitigate the risks, but it does not reflect the effectiveness, efficiency, or sufficiency of the controls. The asset profile is a description of the resources and capabilities that the organization possesses or relies on, but it does not indicate the value, vulnerability, or interdependency of the assets. The key risk indicators (KRIs) are metrics that measure the level and trend of the risks, but they do not explain the causes, impacts, or responses to the risks.
