The most helpful factor to align when defining thresholds for control key performance indicators (KPIs) is the control performance with the risk tolerance of business owners. Control KPIs are metrics that measurethe effectiveness and efficiency of the controls that are implemented to mitigate the risks. By aligning the control performance with the risk tolerance of business owners, the thresholds for control KPIs can reflect the acceptable level of risk and the desired level of control for the business processes and objectives. Information risk assessments with enterprise risk assessments, key risk indicators (KRIs) with risk appetite of the business, andcontrol KPIs with audit findings are other possible factors to align, but they are not as helpful as control performance with risk tolerance of business owners. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 12; CRISC Review Manual, 6th Edition, page 215.

The most important action for the risk practitioner to take when a risk assessment has identified increased losses associated with an IT risk scenario is to update the risk rating. A risk rating is a measure of the overall level of risk, based on the combination of the probability and impact of the risk scenario. A risk rating helps to prioritize the risks, communicate the risk exposure, and monitor the risk response. Updating the risk rating is the most important action, because it reflects the current state and magnitude of the risk, and it triggers the review and revision of the risk response plan, if needed. Updating the risk rating also ensures that the risk register and the risk profile are accurate and complete, and that the risk management process is consistent and effective. The other options are not the most important action, although they may be related or subsequent steps in the risk management process. Reevaluating inherent risk is a part of the risk analysis process, which estimates the probability and impact of the risk scenario before considering the existing controls. Reevaluating inherent risk can help to identify the root causes and drivers of the risk, and to assess the effectiveness and efficiency of the controls, but it does not change the overall level of risk or the risk response plan. Developing new risk scenarios is a part of the risk identification process, which identifies and describes the potential events or situations that could affect the achievement of the objectives. Developing new risk scenarios can help to expand the scope and coverage of the risk management process, and to address the emerging or changing risks, but it does not update the existing risk scenarios or the risk response plan. Implementing additional controls is a part of the risk response process, which selects and executes the appropriate actions to reduce, avoid, share, or exploit the risk. Implementing additional controls can help to mitigate the risk and achieve the desired risk level, but it is not the first or the only option, as it depends on the risk appetite, tolerance, and capacity of the organization, and the cost-benefit analysis of the controls. References = Risk Register Template and Examples | Prioritize and Manage Risk, How to Write Strong Risk Scenarios and Statements - ISACA, IT Risk Resources | ISACA

The best way to ensure that access remains appropriate for an organization that practices the principle of least privilege is to review user access rights on a regular basis by obtaining an access control matrix and approval from the user’s manager. An access control matrix is a table that shows the access rights and permissions of each user or role for each resource or function. An access control matrix helps to verify that the users have the minimum level of access required to perform their duties, and to identify any unauthorized or excessive access rights. Approval from the user’s manager helps to confirm that the user’s access rights are consistent with their current role and responsibilities, and to authorize any changes or exceptions as needed. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.2.2, page 1281

Defining recovery time objectives (RTOs) and acceptable data loss thresholds is critical for effective disaster response, ensuring recovery activities are aligned with business priorities. This supportsBusiness Continuity Planning.
