Enabling Security Features

By default, Elasticsearch security features are disabled. To enable them, you need to configure Elasticsearch and restart it.

Step 1: Update the Configuration

Open the elasticsearch.yml configuration file and add the following settings:

xpack.security.enabled: true

Step 2: Generate Certificates

Elasticsearch requires transport and HTTP layer encryption. Use the elasticsearch-certutil tool to generate the necessary certificates.

bin/elasticsearch-certutil ca
bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12

Follow the prompts to generate the certificates.

Step 3: Configure the Keystore

Add the generated certificates to the Elasticsearch keystore:

bin/elasticsearch-keystore add xpack.security.transport.ssl.keystore.secure_password
bin/elasticsearch-keystore add xpack.security.transport.ssl.truststore.secure_password

Step 4: Restart Elasticsearch

Restart Elasticsearch to apply the changes.

bin/elasticsearch

Elasticsearch is a powerful distributed search and analytics engine widely used for logging, monitoring, and data analysis. To protect your data and ensure secure access, setting up API authentication is essential.

This article will guide you through the process of configuring Elasticsearch API authentication with detailed examples and outputs. We will cover basic authentication, API keys, and role-based access control (RBAC).
