Isaca CRISC Questions Answers

The most important concern when assigning multiple risk owners for an identified risk is that accountability may not be clearly defined. Accountability is the obligation of an individual or group to take responsibility for the risk and its associated actions and outcomes. If multiple risk owners are assigned for the same risk, there may be confusion, conflict, or overlap in their roles and responsibilities, and they may not be held accountable for the risk management performance. Risk ratings being inconsistently applied, different risk taxonomies being used, and mitigation efforts being duplicated are other possible concerns, but they are not as important as accountability not being clearly defined. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 12; CRISC Review Manual, 6th Edition, page 215.

Threat-based risk event modeling often involves significant expert judgment: choosing plausible threats, estimating their capability, attack paths, and motivations, and modeling multi-step attack scenarios. According to CRISC, such modeling demands strong justification and documented rationale because assumptions and inputs may be challenged by stakeholders and auditors. Semi-quantitative approaches and ALE calculations also require explanation, but they are generally based on standardized scales, historical data, or accepted formulas. MTBF is an engineering reliability metric, usually based on vendor data or operational history, requiring limited justification from a risk perspective. Threat-based modeling, however, drives critical decisions about controls and investment, and because it can be sensitive to subjective inputs, risk practitioners must carefully justify scenario selection, likelihood estimates, and impact assumptions to maintain credibility and enable informed governance decisions.

The best recommendation to reduce the risk associated with potential system compromise when a vendor stops releasing security patches and updates for a business-critical legacy system is to segment the system on its own network. Network segmentation is the process of dividing a network into smaller subnetworks or segments, based on different criteria, such as function, location, or security level. Network segmentation helps to isolate the system from the rest of the network, and limit the exposure and access to the system. Network segmentation also helps to improve the performance and security of the network, by reducing the network traffic and congestion, and enhancing the monitoring and control capabilities. The other options are not as effective as segmenting the system on its own network, although they may provide some additional protection or recovery options. Ensuring regular backups take place, virtualizing the system in the cloud, and installing antivirus software on the system are all measures that can helpto reduce the risk of data loss or system damage, but they do not address the root cause of the risk, which is the lack of security patches and updates for the system. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.2.1, page 3-11.

The most important characteristic of an effective risk management program is that risk ownership is assigned. Risk ownership is the accountability and authority to manage a risk1. Assigning risk ownership means identifying and assigning the person or entity who is responsible for evaluating, treating, monitoring, and reporting on a specific risk2. Assigning risk ownership is essential for ensuring that the risk management program works effectively and efficiently, as it helps to:

Clarify the roles and responsibilities of the different functions or groups involved in risk management and internal control;

Ensure that the risks are managed in accordance with the organization’s objectives, strategies, and risk appetite;

Provide guidance and support to the risk owners in identifying, assessing, and mitigating the risks;

Monitor and evaluate the performance and effectiveness of the risk owners and the risk response actions;

Communicate and report on the risk status and issues to the relevant stakeholders and authorities. The other options are not the most important characteristic of an effective risk managementprogram, as they are either less relevant or less specific than assigning risk ownership. Risk response plans are documented. This option is a consequence or outcome of an effective risk management program, not a characteristic of it. Risk response plans are the actions or measures that are taken to modify the risk, such as reducing, avoiding, transferring, or accepting the risk3. Documenting risk response plans means recording and maintaining the details and outcomes of the risk responseactions, such as the objectives, scope, resources, timelines, performance indicators, and results4. Documenting risk response plans can help to improve the consistency and transparency of the risk management process, as well as to support the monitoring and evaluation of the risk response actions. However, documenting risk response plans is not the most important characteristic of an effective risk management program, as it does not address the accountability and authority for managing the risk. Controls are mapped to key risk scenarios. This option is a specific or narrow example of an effective risk managementprogram, not a general or broad characteristic of it. Controls are the measures or actions that are taken to reduce the likelihood or impact of a risk, or to increase the likelihood or impact of an opportunity5. Mapping controls to key risk scenarios means linking the controls to the specific situations or events that may affect the organization’s objectives, operations, or performance6. Mapping controls to key risk scenarios can help to enhance the design and implementation of the controls, as well as to evaluate the effectiveness and efficiency of the controls in mitigating the risk. However, mapping controls to key risk scenarios is not the most important characteristic of an effective risk management program, as it does not cover the other aspects of risk management, such as risk identification, assessment, treatment, and monitoring. Key risk indicators are defined. This option is a component or element of an effective risk management program, not a characteristic of it. Key risk indicators are the metrics that measure thelevel and trend of a risk that may affect the organization’s objectives, operations, or performance7. Defining key risk indicators means establishing and maintaining the criteria and methods for measuring and reporting on the risk8. Defining key risk indicators can help to enhance the risk identification, assessment, and reporting processes, as well as to support the risk decision making and prioritization. However, defining key risk indicators is not the most important characteristic of an effective risk management program, as it does not indicate the accountability and authority for managing the risk. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.1.1, Page 85.
