How to filter NULL or empty values

Does anyone have a good workaround for this issue?

tried many of the former suggestions in this forum, like in here (https://community.mcafee.com/t5/Security-Information-and-Event/Is-there-any-way-to-filter-destinatio...)

but nothing capture correctly. I still left with null values.

Since the thread is also a bit old, has anyone overcome this issue and can help?

Thank you

Re: How to filter NULL or empty values

Hi Prashanth 

thank you for reaching out

I did. when using query filter "source user = regex ($)" I'm getting only fields that contain values, so that OK.

BUT, what is the most efficient way or correct way to implement it within a correlation rule?

source user could be "in" or "not in" ONLY conditions
