Skip this step if you have already configured the Microsoft Graph Security API Source.
Use the Cloud-to-Cloud Integration for Microsoft Graph Security API to ingest security alerts data from the Microsoft Purview Data Loss Prevention to the Sumo Logic platform.
Search alerts
Use the following query to retrieve alerts generated by the Microsoft Purview Data Loss Prevention.
_sourcecategory=Labs/MicrosoftGraphSecurity
| json field=_raw "serviceSource" as service_source
| where service_source = "dataLossPrevention"
Analyse alerts
Use the following query to extract detailed insights from the alert data:
_sourceCategory=Labs/MicrosoftGraphSecurity
|json"id","status","severity","category","title","description","classification","determination","serviceSource","detectionSource","alertWebUrl" ,"comments[*]","evidence[*]"as alert_id,status,severity,category,title,description,classification,determination,service_source,detection_source,alert_url,comments,evidence_info nodrop
| where service_source = "dataLossPrevention"
| where severity matches "*" and status matches "*" and classification matches "*"
| if(isNull(category),"-",category) as category
| if(isNull(classification),"-",classification) as classification
| if(isNull(determination),"-",determination) as determination
| count by _messageTime,status,severity,category,title,description,classification,determination,alert_url,alert_id
| formatDate(toLong(_messageTime), "dd-MM-yyyy HH:mm:ss") as time
