    📌 Learn more about security configuration

  2. Set Up SSL/TLS

    • Generate certificate files: elasticsearch.crt, elasticsearch.key
    • Configure in elasticsearch.yml: 
      xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.key_file: /etc/elasticsearch/elasticsearch.key

  3. Create User Roles
    Use the following API to define roles: 

    POST /_security/role/my_role
{
  "cluster": ["monitor"],
  "indices": [
    {
      "names": ["*"],
      "privileges": ["read", "search"]
    }
  ]
}
