That's a good question, I encounter the case issue as well in using elastic.
We have no plans to change existing categories, there are a few new ones we
have tossed around about adding, but no plans to change the existing.
For our Suricata 5 ruleset we made new category suggestions to the official
Suricata classifications.config (
As we are intertwined with OISF/Suricata there, we wanted to make sure to
maintain the same classifications.config so there wouldn't be issues. May
want to pose this question there as well.
