Within Microsoft 365 Defender, which tab should you navigate to identify all entities impacted by an incident?

To identify all entities impacted by an incident within Microsoft 365 Defender, navigating to the Evidence and Response tab is the most effective choice. This tab provides a comprehensive view of all entities that are directly related to the incident, including users, devices, and applications that may have been affected. It consolidates relevant evidence and artifacts associated with the incident, making it easier for security analysts to assess the scope and severity of the impact.

The Evidence and Response section enables analysts to delve into the details of what occurred, understand the relationships between affected entities, and take appropriate remediation steps. This information is crucial for incident response, as it helps analysts determine the breadth of the incident and any necessary follow-up actions.

While the other tabs, like Investigations or Alerts, provide valuable information regarding security events or activities, they do not focus specifically on outlining all entities impacted by a particular incident. Thus, the Evidence and Response tab offers the most relevant information needed for understanding the full impact of an incident.
