@aalves1 out of the box the WMI AD event source will send the entire contents of the security log to the Raw Log log set, from there you can build you queries or detections for any events which aren’t sent to a parsed logset such as AD Admin Activity
What you have outlined regarding the audit policy is a necessary step to ensure the events are being audited also
I’m not sure I follow, are you asking how to audit these events or are you saying you gave rights to the service account for the event source? The event source doesn’t make any auditing changes on your behalf
I gave rights to the account… Now I am questioning myself if I need this action. Assuming that the Account doesn’t have DOmain Admin rights - I did the WMI rights configuration.
