A standardized risk taxonomy is a common language and structure for identifying, analyzing, and reporting risks across the enterprise. It enables consistent and comparable risk assessment and aggregation, as well as clear communication and coordination among different divisions. A list of control deficiencies, an enterprise risk ownership policy, and an updated risk tolerance metric are not sufficient to enable management of risk at the enterprise level, as they do not address the issue of risk alignment and integration among divisions.

According to the CRISC Review Manual (Digital Version), the best course of action when a risk assessment has identified that an organization may not be in compliance with industry regulations is to conduct a gap analysis against compliance criteria, which is a method of comparing the current state of compliance with the desired or required state of compliance. Conducting a gap analysis against compliance criteria helps to:
Identify and evaluate the differences or discrepancies between the compliance requirements and the actual compliance practices and capabilities Assess the impact and severity of the compliance gaps on the organization's objectives and performance Prioritize the compliance gaps based on their urgency and importance Develop and implement appropriate actions or measures to close or reduce the compliance gaps Monitor and measure the effectiveness and efficiency of the actions or measures taken to address the compliance gaps References = CRISC Review Manual (Digital Version), Chapter 1: IT Risk Identification, Section 1.5: IT Risk Identification Methods and Techniques, pp. 34-351

The risk practitioner shouldfirst review the methodology of the BIAbecause the BIA identifies critical processes and the impacts of disruptions. This ensures that any identified risks are grounded in reliable, updated business impact data.

Changes in methods used to calculate probability present the greatest challenge for an IT risk practitioner who wants to report on trends in historical IT risk levels, as they may introduce inconsistency and incomparability in the risk assessment results over time. Probability is a key factor in determining the level and priority of IT risks, and different methods may produce different values for the same risk scenario. For example, some methods may use historical data, expert judgment, or simulation techniques to estimate the likelihood of a risk event. If the methods used to calculate probability change frequently or vary across different business units or processes, the IT risk practitioner may face difficulty in aggregating, normalizing, and reporting the risk levels and trends. The other options are not the greatest challenges for reporting on trends in historical IT risk levels, although they may pose some difficulties or limitations. Qualitative measures for potential loss events are subjective and imprecise, but they can still provide a relative ranking of risks and their impacts. Changes in owners for identified IT risk scenarios may affect the accountability and responsibility for managing the risks, but they do not necessarily affect the risk levels or trends. Frequent use of risk acceptance as a treatment option may indicate a high risk appetite or tolerance, but it does not prevent the IT risk practitioner from reporting on the risk levels or trends.
