CRISC Exam Dumps - Certified in Risk and Information Systems Control

The best way to prevent technical vulnerabilities from being exploited is to update the software with the latest patches and updates. Patches and updates are software modifications that fix the known bugs, errors, or flaws in the software. They also improve the performance, functionality, and security of the software. By updating the software with the latest patches and updates, the company can reduce the exposure and likelihood of the technical vulnerabilities, and protect the software from potential attacks or exploits. The other options are not as effective as updating the software with the latest patches and updates, as they are related to the quality assurance, legal protection, or error handling of the software, not the prevention or mitigation of the technical vulnerabilities. References = Risk and Information Systems Control Study Manual, Chapter 3: IT Risk Response, Section 3.3: IT Risk Response Implementation, page 145.

The most likely factor to change as a result of a zero-day vulnerability being discovered in a globally used brand of hardware server that allows hackers to gain access to affected IT systems is the risk likelihood. Risk likelihood is the probability or frequency of a risk event occurring, or the possibility of a risk event occurring within a given time period. Risk likelihood is one of the key dimensions of risk analysis, along with the risk impact. Risk likelihood helps to determine the severity and priority of the risk, and to select the most appropriate and effective risk response. Risk likelihood also helps to evaluate the cost-benefit and trade-off of the risk response, and to measure the residual risk and the risk performance. The risk likelihood is likely to change as a result of a zero-day vulnerability, because a zero-day vulnerability is a security flaw that has been discovered but not yet patched by the vendor, which means that it can be exploited by hackers before the affected systems can be updated or protected. A zero-day vulnerability increases the risk likelihood, because it creates a window of opportunity for hackers to launch attacks that could compromise the affected systems, and because it may not be detected or prevented by the existing security controls or measures. The other options are not as likely to change as the risk likelihood, although they may also be affected or influenced by the zero-day vulnerability. Control effectiveness, risk appetite, and key risk indicator (KRI) are all factors that could change as a result of a zero-day vulnerability, but they are not the most likely factor to change. Control effectiveness is the extent to which the risk controls or responses achieve the intended risk objectives or outcomes. Control effectiveness could change as a result of a zero-day vulnerability, because the existing controls may not be able to detect or prevent the exploitation of the vulnerability, or because new or additional controls may be needed to address the vulnerability. However, control effectiveness is not the most likely factor to change, because it depends on the type and level of the controls that are already in place or that can be implemented, and because it may not change until the vulnerability is actually exploited or the risk response is executed. Risk appetite is the amount and type of risk that the organization is willing to accept or pursue in order to achieve its objectives. Risk appetite could change as a result of a zero-day vulnerability, because the vulnerability could affect the organization’s objectives or operations, and because the organization may need to adjust its risk tolerance or threshold to cope with the vulnerability. However, risk appetite is not the most likely factor to change, because it is a strategic and long-term decision that is driven by the organization’s mission, vision, values, and strategy, and because it may not change until the vulnerability is resolved or the risk impact is realized. Key risk indicator (KRI) is a metric that measures thelikelihood and impact of risks, and helps monitor and prioritize the most critical risks. KRI could change as a result of a zero-day vulnerability, because the vulnerability could increase the likelihood and impact of the risks, and because the organization may need to update or revise its KRI to reflect the current risk situation. However, KRI is not the most likely factor to change,because it is a monitoring and reporting tool that is derived from the risk analysis and response, and because it may not change until the vulnerability is exploited or the risk response is implemented. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.3.1, page 4-25.

 A cost-benefit analysis is a technique that compares the costs and benefits of different risk response strategies, such as mitigating, transferring, avoiding, or accepting risks. A cost-benefit analysis can help justify investment in risk response strategies by showing the expected return on investment, the net present value, the break-even point, and the cost-effectiveness of each option.A cost-benefit analysis can also help prioritize the most optimal risk response strategies based on the available resources, the risk appetite, and the stakeholder expectations. References = Risk and Information Systems Control Study Manual, Chapter 3: Risk Response and Mitigation, Section 3.4: Risk Response Selection, p. 156-157.

 Business process owners are the most important to include in the assessment of existing IT risk scenarios, as they have the authority and responsibility to manage the business processes and their associated risks and controls, and to provide the business perspective and requirements for the IT risk scenarios. Technology subject matter experts, business users of IT systems, and risk management consultants are not the most important to include, as they may have different roles and responsibilities related to the technical, operational, or advisory aspects of IT risk scenarios, respectively, but they do not own the business processes or the IT risk scenarios. References = CRISC Review Manual, 7th Edition, page 101.

Regular reviews with stakeholders ensure the risk scenarios are current, complete, and relevant. Stakeholders provide operational and strategic insights, enabling the identification of new, evolving, or obsolete risks. Periodic reviews foster dynamic and continuous alignment of risk scenarios with the business context and threat landscape.

The second line of defense is responsible for challenging the risk decision making of the first line of defense, which is the business process owners and managers. The second line of defense also provides oversight, guidance, and support to the first line of defense in implementing andmaintaining effective risk management practices. The second line of defense includes functions such as risk management, compliance, quality assurance, and internal audit.
