Encrypt the Elasticsearch Transport Network

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. In this hands-on lab, you will do the following: * Encrypt the transport network of an Elasticsearch cluster * Enable user authentication in Elasticsearch * Set built-in Elasticsearch user passwords

  1. Challenge

    Configure transport network encryption.

    Using the Secure Shell (SSH), log in to each node as cloud_user via the public IP address.

    Become the root user with:

    sudo su -
    

    Add the following to /etc/elasticsearch/elasticsearch.yml on each node:

    # --------------------------------- Security -----------------------------------
    #
    xpack.security.enabled: true
    xpack.security.transport.ssl.enabled: true
    xpack.security.transport.ssl.verification_mode: certificate
    xpack.security.transport.ssl.keystore.path: certificate.p12
    xpack.security.transport.ssl.truststore.path: certificate.p12
    
  2. Challenge

    Restart Elasticsearch.

    Start Elasticsearch with:

    systemctl start elasticsearch
    
  3. Challenge

    Set the password for each built-in user.

    Set the built-in user passwords using the elasticsearch-setup-passwords utility on the master-1 node:

    /usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive
    

    Use the following passwords:

    User: elastic
    Password: elastic_566
    
    User: apm_system
    Password: apm_system_566
    
    User: kibana
    Password: kibana_566
    
    User: logstash_system
    Password: logstash_system_566
    
    User: beats_system
    Password: beats_system_566
    
    User: remote_monitoring_user
