I have gone through the documentation here https://www.elastic.co/guide/en/x-pack/v5.0.0-alpha3-docs/security-privileges.html
However, I still do not understand the meaning. Does the indices privileges are all related to the command made in the console?
How about if I use logstash to feed data into ES, how can it be used to filter users for creating index through logstash based on security concerns
