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.
