Identifying incidents that have been closed by automated investigations

Copper Contributor

Is it possible to identify security incidents in Microsoft Sentinel which have been closed automatically after one of the Defender/Microsoft products has carried out an automated investigation and closed the incident?

It doesn’t look like there are any tags added to these incidents when that happens and the “AIR” option in the Automation rule section in Sentinel also doesn’t appear to work.

I would start with something like this:
| where Status == "Closed"
| where TimeGenerated > ago(1d) 

| where tostring(AdditionalData.alertProductNames) contains "Microsoft Defender"
| project ModifiedBy, IncidentNumber, Title, Description, Status


You could then modify this to look for certain services. 


Hope this helps
