ISACA CRISC - Certified in Risk and Information Systems Control Certification Exam

Key control indicators (KCIs) are metrics that measure how well a specific control is performing in reducing the causes, consequences, or likelihood of a risk1. Key risk indicators (KRIs) are metrics that measure changes in the risk exposure or the potential impact of a risk2. By linkingan effective KCI to relevant KRIs, the organization can monitor changes in the risk environment and assess how the control is influencing the risk level3. This can help the organization to: Identify emerging or escalating risks and take timely and appropriate actions Evaluate the effectiveness and efficiency of the control and make improvements if needed Align the control with the risk appetite and tolerance of the organization Communicate the risk and control status to stakeholders and regulators

According to the CRISC Review Manual, a root cause analysis is a technique that identifies the underlying causes of an event or a problem. It helps to determine the most effective actions to prevent or mitigate the recurrence of the event or problem. A root cause analysis is the best approach for the risk practitioner to take in this scenario, because it will help to understand why the number of emergency changes has increased substantially and what can be done to address the issue. The other options are not the best approaches, because they do not address the underlying causes of the problem. Temporarily suspending emergency changes may disrupt the business operations and create more risks. Documenting the control deficiency in the risk register is a passive action that does not resolve the problem. Continuing monitoring change management metrics is an ongoing activity that does not provide any insight into the problem.

Utilizing secure encryption protocols is the most important factor to mitigate risk associated with data privacy when implementing a new Software as a Service (SaaS) speech-to-text solution, as it ensures that the data is protected from unauthorized access, interception, or modification during the transmission and storage in the cloud. Setting up multi-factor authentication for users, approving the solution architecture by IT, and including a risk transfer clause in the contract are not the most important factors, as they may not address the data privacy issue, but rather the data access, quality, or liability issue, respectively.

A KRI is a measure used by an organization to measure the health of a particular risk. In this case, the risk practitioner is developing a metric to measure the risk associated with security threats that were not identified by antivirus software12.

A high number of exceptions often indicate misalignment between policies and business needs. Reviewing policies helps determine if they are overly restrictive or need adjustments to reduce exceptions while maintaining security.
