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.

Residual risk is the amount of risk that remains after the implementation of risk mitigation controls. If the fraud detection controls in an online payment system do not perform as expected, the residual risk will most likely change as a result, because the controls will not be able toreduce the impact or likelihood of the fraud risk as intended. The residual risk may increase or decrease depending on the performance of the controls, and the risk practitioner may need to adjust the risk response strategy accordingly. The other options are not as likely to change as the residual risk, because they are not directly affected by the performance of the controls, but rather depend on other factors, such as the source of the risk, the organization’s objectives, or the external environment, as explained below:

A. Impact is the extent or magnitude of the harm or loss caused by a risk. The impact of the fraud risk in an online payment system may not change as a result of the controls’ performance, becausethe impact is determined by the potential consequences of the fraud, such as financial losses, reputational damage, or legal liabilities, which are independent of the controls.

C. Inherent risk is the amount of risk that exists before the implementation of any risk mitigation controls. The inherent risk of the fraud risk in an online payment system may not change as a result of the controls’ performance, because the inherent risk is determined by the nature and characteristics of the risk, such as the type, source, or frequency of the fraud, which are independent of the controls.

D. Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. The risk appetite of the organization may not change as a result of the controls’ performance, because the risk appetite is determined by the organization’s strategy, culture, and values, which are independent of the controls. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.1.1, page 32. What is Residual Risk?

The best action for the risk practitioner to take when business areas within an organization have engaged various cloud service providers directly without assistance from the IT department is to recommend a risk assessment be conducted. A risk assessment is a process of identifying, analyzing, and evaluating the risks associated with the use of cloud services, such as financial, privacy, compliance, security, performance, quality, and technical risks12. A risk assessment can help to determine the current and potential risk exposure and impact of the cloud services, as well as the effectiveness and efficiency of theexisting or proposed controls. A risk assessment can also help to prioritize the risks and to develop and implement appropriate risk response strategies and plans, such as risk avoidance, reduction, sharing, or acceptance. Recommending a risk assessment is the best action, because it can provide valuable information and guidance to the business areas and the IT department for managing the cloud services in a consistent, effective, and efficient manner, and for aligning the cloud services with the organizational objectives, strategy, and risk appetite. The other options are not the best action, although they may be related or subsequent steps in the risk management process. Recommending the IT department remove access to the cloud services is a drastic and impractical action, as it may disrupt the business operations and services, and it may not address the underlying causes or drivers of the cloud service adoption. Engaging with the business area managers to review controls applied is a useful and collaborative action, as it can help to understand and evaluate the current state and practices of the cloud service usage, and to identify and address any gaps or issues in the control environment. However, this action should be based on or supported by a risk assessment, rather than preceding or replacing it. Escalating to the risk committee is a reporting and communication action, as it can help to inform and involve the senior management and other stakeholders in the risk management process, and to obtain their support and approval for the risk response actions. However, this action should be done after or along with a risk assessment, rather than before or instead of it. References = Best Practices to Manage Risks in the Cloud - ISACA, Cloud Risk Management - PwC UK

Identifying risk events is essential for developing realistic and relevant risk scenarios. This step enables the creation of scenarios that reflect actual vulnerabilities and potential disruptions, adhering to the CRISC's focus onRisk Identification.
