Elastic Search Indexing --Security User Based

Hi all,

Mine is a generic question, hence i am not specifying the ELK Cluster version etc.

I have installed Search guard, and managed to achieve Index level and Document level querying security.

How can i make sure that only a certain user is able to index data into Elastic cluster ? Is this something that can be done via Search guard.

Can i create a user which can only index data and not be able to login into Kibana and do other operations ?

Any guidance is appreciated, thank you experts
