Define User Access Control in Elasticsearch
No matter what technology we are working with, we always need to be mindful of security. Big data platforms are certainly no exception, as they can contain massive amounts of sensitive data that must be protected. Elasticsearch has made securing your cluster very easy with native security configurations and tools to ensure that your data is only accessible to authorized users. One of the best and most obvious ways of securing data is through limited user access control via user authentication and authorization. In this hands-on lab, you are given the opportunity to create a role in an Elasticsearch cluster to authorize a specific level of access to some data. Then you will get to create a user who will be given the previously created role which, after authentication, will be authorized to perform any operations permitted by said role.
