New to SIEM - not sure what to do with new case

Regular Visitor

I setup my SIEM with Data Connector to MS Security Events and then installed "Failed Login Attempts within 10 minutes" alert. Then I triggered this alert which resulted in a Case. Now what?

 

I can't seem to drill down to find out which account or host was part of this alert. Maybe I don't have entities mapped correctly, but I was hoping I'd have point and click access to the details. Actually I was somewhat surprised that I had to go out to a Github repo to find some prebuilt alerts.

 

I'm feeling like I'm in over my head and that I'm either not using this correctly or it's just a framework on which I'm expected to build out what I need. If it's the latter, can anyone recommend how I can get up to speed on this work?

You can look at the "Hunting with Jupyter Notebooks" articles published here to give you an idea of how to use Notebooks to perform a more in-depth analysis
