In Microsoft Defender for Office 365, where should a security analyst check to understand the automatic actions taken by Automated Investigation and Response (AIR) regarding a weaponized URL?

The Actions tab in the investigation is the appropriate place for a security analyst to check regarding the automatic actions taken by Automated Investigation and Response (AIR) concerning a weaponized URL. This tab specifically outlines the automated actions that have been executed during the investigation of an incident. In the case of a weaponized URL, AIR may have blocked the URL, quarantined related messages, or implemented other remedial measures based on the findings during the investigation.

This clarity in the Actions tab provides a transparent view of what steps were taken by the system to mitigate threats effectively, allowing the analyst to understand the response to the incident and to document or communicate these actions as necessary. By checking this tab, the analyst can also evaluate the effectiveness of AIR's intervention and any further action that might be required based on the automated outcomes.
