Which category of the Respond (RS) function involves assessing the impact of an incident?

The category of the Respond function that involves assessing the impact of an incident is Analysis. This stage is crucial in the incident response process, as it allows teams to understand the extent and implications of the security incident. Through analysis, organizations evaluate the data surrounding the incident, identify affected systems and data, and understand the potential harm that has been caused or could be caused if not addressed properly. This comprehensive assessment helps inform the subsequent response actions and ensures that appropriate measures are taken to mitigate further risks.

In contrast, other categories such as Mitigation focus on taking preventive measures to limit damage and prevent recurrence, while Recovery pertains to restoring systems and operations after the incident has been managed. Comprehension, while related to understanding the incident, does not specifically address the assessment of its impact in the detailed manner that Analysis does. Thus, Analysis is the most appropriate category for assessing the impact of an incident within the Respond function.
