Insights? That is SOP for CISA right there. "We recommend that you should do this *but* if it does not work it is up to you to figure out how we screwed up." You should see the amazing dysfunction of CISA trying to explain how to fill out/answer a data call for any recently released BOD. It happens.every.single.time.

These are not default Snort classtypes. Can someone provide some insight on how to either define these classtypes OR provide a good alternative classtype? Thanks in advance for any insight you can provide!
