Emerging risk is a risk that is new or evolving, and has the potential to significantly affect the enterprise's objectives, performance, or reputation. Emerging risk can arise from changes in the internal or external environment, such as technological innovations, regulatory developments, or social trends. The best way to support communication of emerging risk is to include it on the next enterprise risk committee agenda. The enterprise risk committee is a group of senior executives who oversee the enterprise-wide risk management program, and provide guidance and direction to the risk owners and practitioners. By including the emerging risk on the agenda, the risk practitioner can ensure that the enterprise risk committee is aware of the risk, its causes, impacts, and likelihood, and can decide on the appropriate risk response strategy and actions. The other options are not the best way to support communication of emerging risk, as they involve different aspects of the risk management process:
* Update residual risk levels to reflect the expected risk impact means that the risk practitioner adjusts the risk levels after considering the existing or planned risk responses. This may not be feasible or accurate for emerging risk, as the risk responses may not be defined or implemented yet, or may not be effective for the new or evolving risk.
* Adjust inherent risk levels upward means that the risk practitioner increases the risk levels before considering any risk responses. This may not reflect the true nature or magnitude of the emerging risk, as the inherent risk levels are based on the assumptions and estimates of the risk practitioner, and may not account for the uncertainties or complexities of the emerging risk.
* Include it in the risk register for ongoing monitoring means that the risk practitioner records and tracks the emerging risk, its causes, impacts, likelihood, responses, and owners. This is an important step in the risk management process, but it does not necessarily support communication of the emerging risk, as the risk register may not be accessible or visible to all the relevant stakeholders, or may not be updated or reviewed frequently enough to capture the changes in the emerging risk.

The most likely cause for a risk practitioner to reassess risk scenarios is a change in the regulatory environment. A regulatory environment is the set of laws, rules, and standards that apply to an organization and its activities, such as data privacy, security, compliance, or governance. A change in the regulatory environment can occur due to various factors, such as new legislation, court rulings, enforcement actions, or industry trends. A change in the regulatory environment can affect the risk scenarios that the organization faces, as it may introduce new or modified risks, or alter the probability or impact of existing risks. For example, a new regulation may require the organization to implement additional or different controls, or to report or disclose more information, which may increase the cost, complexity, or vulnerability of the organization's processes and systems. A change in the regulatory environment may also affect the risk appetite, tolerance, and capacity of the organization, as it may impose different requirements or expectations for the organization's risk management performance and outcomes. Therefore, a risk practitioner should reassess the risk scenarios when there is a change in the regulatory environment, to ensure that the risk scenarios are accurate, complete, and relevant, and that the risk response strategies and plans are appropriate, effective, and compliant. The other options are not the most likely cause, although they may be related or influential to the riskscenarios. A change in the risk management policy is a change in the rules and guidelines that define how the organization manages its risks, such as the roles and responsibilities, the processes and procedures, the tools and techniques, or the reporting and communication. A change in the risk management policy can affect the risk scenarios, as it may change the way the organization identifies, analyzes, evaluates, and responds to the risks, but it does not directly create or modify the risks themselves. A major security incident is an event or situation that compromises the confidentiality, integrity, or availability of the organization's information or systems, such as a data breach, a denial-of-service attack, or a ransomware infection. A major security incident can affect the risk scenarios, as it may indicate or reveal the existence or severity of the risks, or trigger or escalate the consequences of the risks, but it is not a cause, rather it is an effect of the risks. An increase in intrusion attempts is an increase in the frequency or intensity of the unauthorized or malicious attempts to access or exploit the organization's information or systems, such as phishing, malware, or brute-force attacks. An increase in intrusion attempts can affect the risk scenarios, as it may increase the likelihood or impact of the risks, or expose or exacerbate the vulnerabilities of the organization's processes and systems, but it is not a cause, rather it is a manifestation of the risks.

A business system is a set of interconnected processes, functions, or activities that support the operations and objectives of a business1. A security gap is a weakness or flaw in a business system that can be exploited by a threat to cause harm or gain unauthorized access2. A control is a measure or mechanism that reduces the likelihood or impact of a security gap or threat3.
The best way to determine whether new controls mitigate security gaps in a business system is to perform a vulnerability assessment. A vulnerability assessment is a process of identifying and evaluating the security gaps and threats in a business system, and testing the effectiveness and efficiency of the controls that are implemented to address them. A vulnerability assessment can help to:
Measure and compare the current and desired state of the security posture and performance of the business system Detect and prioritize the most critical and urgent security gaps and threats that may compromise the business system or its objectives Validate and validate the adequacy and reliability of the new controls and their ability to prevent, detect, or respond to security incidents or breaches Provide feedback and recommendations for improving the security of the business system and enhancing the security awareness and culture of the organization References = What is a Business System?, What is a Security Gap?, What is a Control?, [What is a Vulnerability Assessment?], [Vulnerability Assessment: A Guide for Business Leaders]

Risk strategies are the plans and actions that an organization adopts to manage its risks and to achieve its objectives. Risk strategies should be aligned with the organization's vision, mission, values, and culture, as well as its internal and external environment. The most important consideration when developing risk strategies is the long-term organizational goals, meaning that the risk strategies should support and enable the organization to pursue and attain its desired future state and outcomes. The long-term organizational goals should guide the risk identification, assessment, response, and monitoring processes, as well as the risk appetite and tolerance levels. The long-term organizational goals should also be communicated and cascaded throughout the organization to ensure the risk awareness and engagement of all stakeholders.

The best course of action to determine the root cause of the high number of policy exceptions approved by senior management is to interview the control owner. The control owner is the person who has the authority and responsibility for designing, implementing, and monitoring the controls that enforce the policy. The control owner can provide insight into the reasons, circumstances, and impacts of the policy exceptions, and the effectiveness and efficiency of the controls. The control owner can also suggest possible improvements or alternatives to the policy or the controls. The other options are not as useful as interviewing the control owner, as they are related to the review, analysis, or testing of the policy or the controls, not the investigation or understanding of the policy exceptions.
