The operational risk associated with attacks on a web application should be owned by the individual in charge of the business function, because they are the primary stakeholder and beneficiary of the web application, and they are responsible for defining and achieving the business objectives and requirements that the web application supports or enables. Anoperational risk is a risk of loss or damage resulting from inadequate or failed internal processes, people, or systems, or from external events. An attack on a web application is a type of operational risk that involves a malicious or unauthorized attempt to compromise the confidentiality, integrity, or availability of the web application, such as a denial-of-service attack, a SQL injection attack, or a cross-site scripting attack. A web application is an application that runs on a web server and can be accessed or used through a web browser, such as an online shopping site, a social media platform, or a web-based email service. A business function is a set of activities or tasks that support or enable the organization’s vision, mission, and strategy, such as marketing, sales, or customer service. A risk owner is a person or role that has the authority and accountability to manage a specific risk, and to implement and monitor the risk response and controls. The individual in charge of the business function should be the risk owner, as they have the best understanding and interest of the web application and its business value and impact, and they have the ability and responsibility to manage the operational risk associated with the attacks on the web application. The individual in charge of network operations, the cybersecurity function, or application development are all possible candidates for the risk owner, but they are not the best choice, as they may not have the same level of stake and influence in the web application and its business objectives and requirements, and they may have different orconflicting priorities or perspectives on the operational risk and its management.

The best metric to demonstrate that servers are configured securely is the total number of servers meeting the baseline for hardening. Hardening is the process of applying security configurations and settings to servers to reduce their attack surface and vulnerability. A baseline is a standard or benchmark that defines the minimum level of security required for servers. By measuring the number of servers that meet the baseline, the organization can assess the effectiveness of its hardening efforts and identify any gaps or deviations. The other metrics, such as exceeding availability thresholds, experiencing hardware failures, or exceeding current patching standards, are not directly related to the security configuration of servers, but rather to their performance, reliability, or maintenance. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.3.2, page 2-25.

The BEST answer is D because a KRI must be linked to a specific risk or risk scenario and should provide an early warning of increased risk exposure. ISACA’s CRISC exam outline includes defining, implementing, refining, monitoring, and analyzing KRIs, KPIs, and KCIs as supporting CRISC tasks. ISACA’s risk indicator explanation distinguishes indicators clearly: a KRI gives an early signal of increased exposure to risk, while a KPI measures performance over time for a specific objective. The uploaded CRISC notes directly support this: the most important consideration when implementing KRIs is linking the metric to a specific risk, and the most important attribute of an effective KRI is that it is linked to a specific risk.

A is too narrow because KRIs may measure many types of risk exposure, not only threat landscape changes. B is incorrect because risk appetite is normally set by governance/senior leadership; KRIs monitor exposure against appetite/tolerance, not refine appetite themselves. C describes a KPI more than a KRI, because process performance monitoring is performance-focused rather than risk-exposure-focused.

Recovery time objectives (RTOs) are the maximum acceptable time frames for restoring the critical functions and processes after a disruption1. RTOs are derived from the business impact analysis (BIA) andreflect the organization’s risk appetite, which is the amount of risk that an organization is willing to accept to achieve its objectives2. Risk tolerance is the level of risk a company is willing to tolerate, and it is affected by a number of factors, including how much uncertainty or financial loss can be tolerated and where those losses will impact operations3. Risk tolerance is used to measure if the risk exposure is within the risk appetite and to implement controls to reduce the residual risk to an acceptable level2. If the majority of core IT application RTOs have exceeded the maximum time defined by the business application owners, it means that the organization is not meeting its risk appetite and is exposed to more risk than it can accept. Therefore, the most likely change as a result is to adjust the risk tolerance to reflect the current reality and to take actions to improve the recovery capabilities and reduce the risk exposure4. Risk forecasting is the process of estimating the potential outcomes and impactsof future events that may affect the organization’s objectives5. Risk forecasting may change as aresult of the RTOs exceeding the maximum time, but it is not the most likely change, as it does not directly address the gap between the risk appetite and the risk exposure. Risk likelihood is the probability of a risk event occurring5. Risk likelihood may change as a result of the RTOs exceeding the maximum time, but it is not the most likely change, as it does not directly measure the impact of the risk event on the organization’s objectives. Risk appetite is the amount of risk that an organization is willing to accept to achieve its objectives2. Risk appetite may change as a result of the RTOs exceeding the maximum time, but it is not the most likely change, as it is a strategic decision that reflects the organization’s vision and mission, and not a tactical response to a specific risk event. References = Risk and Information Systems Control Study Manual, Chapter 5: Risk Response and Mitigation, Section 5.3: Business Continuity Planning, pp. 227-238.
