How to config Single node for Single Cluster (Standalone Cluster)

Hello All,

I have my local machine. I want to config elastic search for only single cluster for single node. (Standalone Server)Means whatever I will created new index, it will available for only to me. Its not accesible to other.
My current scenario these indexes are available to other, so they can make any changes.But I don't want it.

I went through some other blogs but not getting best solution.
So can you please let me know steps for same?

Quick response will be appreciable.

Thanks in advance.

Thanks
