Determining if organizational risk is tolerable requires understanding the organization’s risk appetite, which is the amount and type of risk that the organization is willing to accept or pursue in order to achieve its objectives1. Understanding the organization’s risk appetite can help to:

Define and communicate the risk tolerance, which is the acceptable or unacceptable level of risk for each risk category or scenario2.

Guide and align the risk identification, analysis, evaluation, and treatment processes, and ensure that the risks are consistent and proportional to the risk appetite3.

Measure and monitor the risk performance and outcome, and ensure that the residual risk (the risk that remains after the risk responses) is within the risk appetite, or take corrective actions if needed4.

The other options are not the best ways to determine if organizational risk is tolerable, because:

Mapping residual risk with cost of controls is a useful but not sufficient way to determine if organizational risk is tolerable, as it provides a quantitative analysis of the trade-off between the risk level and the risk response cost5. However, mapping residual risk with cost of controls does not consider the qualitative aspects of the risk, such as the impact on the organization’s strategy, culture, or reputation.

Comparing against regulatory requirements is a necessary but not sufficient way to determine if organizational risk is tolerable, as it ensures that the organization complies with the applicable laws, rules, or standards that govern its activities and operations6. However, comparing against regulatory requirements does not guarantee that the organization meets its own objectives and expectations, which may be higher or lower than the regulatory requirements.

Comparing industry risk appetite with the organization’s risk appetite is a helpful but not sufficient way to determine if organizational risk is tolerable, as it provides a reference or a standard for benchmarking the organization’s risk level and performance with its peers or competitors7. However, comparing industry risk appetite with the organization’s risk appetitedoes not ensure that the organization addresses its specific or unique risks, which may differ from the industry risks.

The most important factor for successful incident response is the timeliness of attack recognition. Incident response is the process of detecting, analyzing, containing, eradicating, recovering, and reporting on security incidents that could affect the organization’s IT systems or data. The timeliness of attack recognition is the speed and accuracy with which the organization can identify and confirm that an attack has occurred or is in progress. The timeliness of attack recognition is crucial for successful incident response, as it affects the ability and effectiveness of the organization to respond to and mitigate the attack, and to minimize the damage and impact of the attack. The other options are not as important as the timeliness of attack recognition, although they may also contribute to or influence the incident response. The quantity of data logged by the attack control tools, the ability to trace the source of the attack, and the blocking of the attack route immediately are all factors that could help or hinder the incident response, but they are not the most important factor for successful incident response. References = CISA Review Manual, 27th Edition, Chapter 5, Section 5.4.1, page 5-32.

Requesting a formal risk acceptance sign-off is the most likely scenario when the residual risk in excess of the risk appetite cannot be mitigated, because it indicates that the organization is willing to tolerate a higher level of risk than it normally would, and that the risk owner has the authority and accountability to accept the risk and its consequences. Risk acceptance is a risk response strategy that involves acknowledging the existence ofa risk and deciding not to take any action to reduce it. Risk acceptance is usually chosen when the cost or effort of mitigating therisk outweighs the potential benefits, or when no feasible mitigation options are available. Residual risk is the risk that remains after applying controls or mitigating factors. Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Inherent risk, cancellation of an initiative, change of risk appetite, and constant residual risk are all possible scenarios that may affect the risk management process, but they are not the most likely to cause a risk practitioner to request a formal risk acceptance sign-off, as they do not necessarily involve a risk owner accepting a higher level of risk than the organization’s risk appetite.

 An exception to the information security policy is a permission to continue operating a system, service, or product that cannot comply with the established information security standards and requirements1. A risk owner is a person or entity that has the authority and accountability for a risk and its management2. A risk practitioner is a person or entity that has the knowledge and skills to perform risk management activities3. A high number of exceptions to the information security policy indicates that there are many systems, services, or products that do not meet the expected level of security and pose potential risks to the organization. The risk practitioner’s greatest concern should be that the aggregate risk, which is the total amount of risk that the organization faces from all sources, is approaching the tolerance threshold, which is the limit beyond which the organization does not want to tolerate the risk4. If the aggregate risk isapproaching the tolerance threshold, it means that the organization is exposed to a high level of risk that may exceed its risk appetite, which is the amount of risk that the organization is willing to accept to achieve its objectives5. This may result in negative consequences for the organization, such as breaches, losses, damages, or reputational harm. Therefore, the risk practitioner should monitor and report the aggregate risk level and the tolerance threshold, and advise the risk owners and the management on the appropriate risk responses and actions to reduce the aggregate risk to an acceptable level. Security policies are being reviewed infrequently, controls are not operating efficiently, and vulnerabilities are not being mitigated are not the risk practitioner’s greatest concern, as they are not directly related to the aggregate risk level and the tolerance threshold. Security policies are being reviewed infrequently is a condition that indicates that the organization’s security policies are not updated or revised regularly to reflect the changes and updates in the security environment and the security requirements6. This may affect the relevance and effectiveness of the security policies, but it does not necessarilyincrease the aggregate risk level or the tolerance threshold. Controls are not operating efficiently is a condition thatindicates that the organization’s controls, which are the measures or actions taken to manage or mitigate the risks, are not performing well or optimally7. This may affect the quality and performance of the controls, but it does not necessarily increase the aggregate risk level or the tolerance threshold. Vulnerabilities are not being mitigated is a condition that indicates that the organization’s vulnerabilities, which are the weaknesses or gaps that may be exploited by the threats, are not being addressed or reduced8. This may increase the likelihood or impact of the risks, but it does not necessarily increase the aggregate risk level or the tolerance threshold. References = 1: IT/Information Security Exception Request Process2: [Risk Ownership - Risk Management] 3: [Risk Practitioner - ISACA] 4: Risk Threshold: Definition, Meaning & Example - PM Study Circle5: Risk Appetite vs Risk Tolerance vs Risk Threshold - projectcubicle6: [Security Policy Review and Update - SANS Institute] 7: [Control Effectiveness and Efficiency - ISACA] 8: [Vulnerability Management - ISACA] : [Risk andInformation Systems Control Study Manual, Chapter 1: IT Risk Identification, Section 1.1: IT Risk Concepts, pp. 17-19.] : [Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.1: Risk Identification, pp. 57-59.] : [Risk and Information Systems Control Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.2: Risk Monitoring, pp. 189-191.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.1: Control Design, pp. 233-235.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.2: Control Implementation, pp. 243-245.] : [Risk and Information Systems Control Study Manual, Chapter 5: Information Systems Control Design and Implementation, Section 5.3: Control Monitoring and Maintenance, pp. 251-253.]
