The primary reason to perform ongoing risk assessments is that the risk environment is subject to change. The risk environment is the external and internal factors that influence the level and nature of the risks that the organization faces1. These factors include economic, political, social, technological, legal, and environmental aspects, as well as the organization's objectives, strategies, culture, and resources2. The risk environment is dynamic and unpredictable, and may change due to various events, trends, or developments that create new or modify existing risks3. Therefore, it is important to perform ongoing risk assessments to identify, analyze, and evaluate the changes in the risk environment, and to adjust the risk response and management accordingly. Ongoing risk assessments help to ensure that the organization's risk profile is up to date and reflects the current reality, and that the organization's risk appetite and tolerance are aligned with the changing risk environment4. The other options are not the primary reason to perform ongoing risk assessments, as they are either less comprehensive or less relevant than the changing risk environment. Emerging risk must be continuously reported to management. This option is a consequence or outcome of performing ongoing risk assessments, not a reason for doing so. Emerging risk is a new or evolving risk that has the potential to affect the organization's objectives, operations, or performance5. Ongoing risk assessments can help to identify and monitor emerging risks, and to report them to management for decision making and action. However, this is not the main reason for performing ongoing risk assessments, as it does not cover the existing or modified risks that may also change due to the risk environment. New system vulnerabilities emerge at frequent intervals. This option is a specific or narrow example of a changing risk environment, not a general or broad reason for performing ongoing risk assessments. System vulnerabilities are weaknesses or flaws in the design, implementation, or operation of information systems that can be exploited by threats to cause harm or loss6.
Ongoing risk assessments can help to discover and assess new system vulnerabilities that may emerge due to technological changes, cyberattacks, or human errors. However, this is not the primary reason for performing ongoing risk assessments, as it does not encompass the other types or sources of risks that may also change due to the risk environment. The information security budget must be justified. This option is a secondary or incidental benefit of performing ongoing risk assessments, not a primary or essential reason for doing so. The information security budget is the amount of money that the organization allocates for implementing and maintaining information security measures and controls7. Ongoing risk assessments can help to justify the information security budget by demonstrating the value and effectiveness of the security measures and controls in reducing the risks, and by identifying the gaps or needs for additional or improved security measures and controls. However, this is not the main reason for performing ongoing risk assessments, as it does not address the purpose or objective of risk assessment, which is to identify, analyze, and evaluate the risks and their impact on the organization.

Senior management participation is essential for the success of an organization's risk management framework, as it demonstrates the commitment, support, and leadership for the risk management activities. Senior management participation also ensures that the risk management framework is aligned with the organization's strategy, objectives, and culture, and that the risk management roles and responsibilities are clearly defined and communicated. Senior management participation also facilitates the allocation of adequate resources, the establishment of risk appetite and tolerance, and the monitoring and reporting of risk performance. Therefore, the lack of senior management participation should be of greatest concern to a risk practitioner, as it indicates a low level of risk maturity and a high level of risk exposure. The other options are not as concerning as the lack of senior management participation, because they do not affect the risk management framework as significantly, and they can be addressed or improved with the involvement of senior management, as explained below:
* A. Unclear organizational risk appetite is a deficiency that can affect the risk management framework, as it can lead to inconsistent or inappropriate risk decisions and responses. However, this deficiency can be resolved or mitigated with the participation of senior management, who can define and communicate the risk appetite and tolerance for the organization, and ensure that they are aligned with the organization's strategy and objectives.
* C. Use of highly customized control frameworks is a deficiency that can affect the risk management framework, as it can create complexity, confusion, or duplication in the control design and implementation. However, this deficiency can be resolved or mitigated with the participation of senior management, who can review and rationalize the control frameworks, and ensure that they are relevant, effective, and efficient for the organization's risk profile and environment.
* D. Reliance on qualitative analysis methods is a deficiency that can affect the risk management framework, as it can limit the accuracy, reliability, and comparability of the risk information and assessment. However, this deficiency can be resolved or mitigated with the participation of senior management, who can support and promote the use of quantitative analysis methods, such as the FAIR framework1, and provide the necessary data, tools, and skills for the risk analysis and evaluation.

The most important information to be communicated during security awareness training is management's expectations. This will help to establish the security culture and behavior of the enterprise, and to align the staff's actions with the enterprise's objectives, policies, and standards. Management's expectations also provide the basis for measuring and evaluating the effectiveness of the security awareness program. Corporate risk profile, recent security incidents, and the current risk management capability are also important information to be communicated during security awareness training, but they are not as important as management's expectations.

The best indicator of the risk appetite and tolerance level for the risk associated with business interruption caused by IT system failures is the recovery time objective (RTO). The RTO is the maximum acceptable time or duration that a business process or an IT system can be disrupted or interrupted before it causes unacceptable impact or harm to the business. The RTO reflects the risk appetite and tolerance level for the business interruption risk, as it indicates how much disruption or interruption the business can tolerate or accept, and how quickly the business needs to resume or recover the business process or the IT system. The RTO also helps to determine the priorities and requirements for the business continuity and recovery planning, and to select and implement the appropriate continuity and recovery strategies and solutions. Mean time to recover (MTTR), IT system criticality classification, and incident management service level agreement (SLA) are not the best indicators of the risk appetite and tolerance level for the business interruption risk, as they are either the measures or the outcomes of the business continuity and recovery performance, and they do not directly indicate how much disruption or interruption the business can tolerate or accept.
