Isaca Updated CRISC Exam Questions and Answers by julian

To make well-informed cybersecurity risk decisions, it is most important to determine and understand the risk rating of scenarios. A risk rating is a measure of the severity and priority of a risk, based on the combination of its impact and likelihood. A risk scenario is a description of a potential event or situation that could adversely affect the organization’s objectives, assets, or processes. By determining and understanding the risk rating of scenarios, the organization can identify the most critical and urgent risks, and select the appropriate risk response strategies accordingly. The other options are not as important as determining and understanding the risk rating of scenarios, because they do not provide a clear and comprehensive view of the risk, but rather focus on specific or partial aspects of the risk management process. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.3.1, page 45.

Key risk indicators (KRIs) are metrics that provide information about the level of exposure to a specific risk or a group of risks.

Reviewing KRIs is the most helpful way to determine the effectiveness of an organization’s IT risk mitigation efforts. This means that the organization monitors and evaluates the actual results and outcomes of the risk responses, compares them with the risk appetite and tolerance of the organization, identifies any deviations or breaches that may require attention or action, and reports them to the appropriate parties for decision making or improvement actions.

The other options are not the most helpful ways to determine the effectiveness of an organization’s IT risk mitigation efforts. They are either secondary or not essential for risk management.

The MOST important consideration when developing IT risk scenarios is the potential threats and vulnerabilities that may have an impact on the business, because they are the key elements of a risk scenario that describe the sources and causes of the risk, and the potential consequences and impacts of the risk on the business objectives and processes. The other options are not as important as the potential threats and vulnerabilities, because:

Option A: The impact of controls on the efficiency of the business in delivering services is a secondary consideration that may affect the cost-benefit analysis of the risk response, but it does not directly affect the identification and assessment of the risk scenario.

Option B: Linkage of identified risk scenarios with enterprise risk management is a good practice that ensures the alignment and integration of the IT risk management with the overall enterprise risk management, but it does not directly affect the identification and assessment of the risk scenario.

Option D: Results of network vulnerability scanning and penetration testing are useful sources of information that may reveal some of the threats and vulnerabilities in the IT environment, but they are not the only or the most important consideration when developing IT risk scenarios, as they may not cover all the aspects and dimensions of the risk. References = Risk and Information Systems Control Study Manual, 7th Edition, ISACA, 2020, p. 104.

Configuration management is a process that establishes and maintains the consistency and integrity of the IT systems and applications throughout their lifecycle. Configuration management involves identifying, documenting, controlling, and auditing the configuration items, such as hardware, software, data, or services, that comprise the IT systems and applications. Configuration management also involves establishing and enforcing the configuration baselines, which are the approved and authorized states of the configuration items. Implementing configuration management will best help ensure that systems comply with an established baseline before deployment, as it will enable the enterprise to verify that the systems meet the specified requirements, standards, and policies, and to detect and correct any deviations or discrepancies. The other options are not as effective as configuration management, as they involve different aspects or outcomes of the IT systems and applications:

Vulnerability scanning is a process that identifies and analyzes the weaknesses or gaps in the IT systems and applications that could be exploited by threats. Vulnerability scanning helps to assessthe security and compliance of the systems, but it does not ensure that the systems comply with an established baseline before deployment, as it may not cover all the aspects or components of the systems, or may not reflect the latest changes or updates of the systems.

Continuous monitoring and alerting is a process that tracks and reports the performance and status of the IT systems and applications on an ongoing basis. Continuous monitoring and alerting helps to identify and respond to any issues or incidents that affect the availability, integrity, or confidentiality of the systems, but it does not ensure that the systems comply with an established baseline before deployment, as it may not prevent or detect the unauthorized or unintended changes or modifications of the systems, or may not provide sufficient information or evidence to verify the compliance of the systems.

Access controls and active logging are processes that restrict and record the access and activities of the users or entities on the IT systems and applications. Access controls and active logging help to protect and audit the IT systems and applications, but they do not ensure that the systems comply with an established baseline before deployment, as they may not address the configuration or quality issues of the systems, or may not be consistent or comprehensive across the systems. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 4, Section 4.2.1.1, pp. 156-157.
