Elasticsearch: Quick Guide to User Access
Unlocking Elasticsearch Security: A Detailed Walkthrough on Setting Up User Access Control for Efficient and Safe Cluster Monitoring.
Elasticsearch is a powerful search and analytics engine. As with any tool that processes and stores data, especially in a clustered environment, user access control is paramount for both data integrity and security. In this guide, we’ll delve into how to set up user access controls specifically for monitoring in a 3-node Elasticsearch cluster.
Scenario
Let's consider a use case to give our guide some context. Imagine being a system administrator for a 3-node Elasticsearch cluster. To optimize cluster support, you've decided to delegate the day-to-day monitoring of the cluster to your Network Operations Center (NOC). But in the spirit of adhering to security best practices, you want to grant the NOC the minimum necessary permissions.
Objective: Grant the NOC access to monitor the cluster without compromising on security.
Step-by-Step Solution:
1. Define the Role for Monitoring
Firstly, we need to define a role that has the necessary permissions for monitoring.
