Microsoft Sentinel Incident Investigation and Incident Management 

After you connected your data sources to Microsoft Sentinel, you want to be notified when something suspicious happens. To enable you to do this, Microsoft Sentinel lets you create advanced analytics rules that generate incidents that you can assign and investigate.
Investigate incidents
Use the investigation graph
An incident can include multiple alerts. It's an aggregation of all the relevant evidence for a specific investigation. An incident is created based on analytics rules that you created in the Analytics page. The properties related to the alerts, such as severity and status, are set at the incident level. After you let Microsoft Sentinel know what kinds of threats you're looking for and how to find them, you can monitor detected threats by investigating incidents.
