Hi,  
Please help me to achieve the following condition.

If (SourceIP of (Winlogbeat – Login as Admin AND Winlogbeat Privilege Escalation) = Same SourceIP - say X)  
AND (Output of the Denied or Allowed Outbound Malicious Traffic Source IP = X)  
Then index the matching documents to a new account index.
