Wazuh

Wazuh is a free, open source and enterprise-ready security monitoring solution for threat detection, integrity monitoring, incident response and compliance. This integration allows you to send Wazuh logs to your Logz.io SIEM account.

Before you begin, you'll need:

Configure Wazuh for JSON logging​

In the Wazuh configuration file (/var/ossec/etc/ossec.conf), find the <logging> tag, and set the <log_format> property to json.

<logging>
  <log_format>json</log_format>
</logging>

Restart Wazuh.

sudo systemctl restart wazuh-manager

Download the Logz.io public certificate​

For HTTPS shipping, download the Logz.io public certificate to your certificate authority folder.

sudo curl https://raw.githubusercontent.com/logzio/public-certificates/master/AAACertificateServices.crt --create-dirs -o /etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt

Add Wazuh as an input​

In the Filebeat configuration file (/etc/filebeat/filebeat.yml), add Wazuh to the filebeat.inputs section.

Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.

note

Filebeat requires a file extension specified for the log input.

# ...
filebeat.inputs:
- type: filestream

  paths:
  - /var/ossec/logs/alerts/alerts.json

  fields:
    logzio_codec: json

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<LOG-SHIPPING-TOKEN>>
    type: wazuh
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h

If you're running Filebeat 7 to 8.1, paste the code block below instead:

# ...
filebeat.inputs:
- type: log

  paths:
  - /var/ossec/logs/alerts/alerts.json

  fields:
    logzio_codec: json

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<LOG-SHIPPING-TOKEN>>
    type: wazuh
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h

Set Logz.io as the output​

If Logz.io is not an output, add it now. Remove all other outputs.

Replace <<LISTENER-HOST>> with the host for your region. 

# ...
output.logstash:
  hosts: ["<<LISTENER-HOST>>:5015"]
  ssl:
    certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']

Start Filebeat​

Start or restart Filebeat for the changes to take effect.

Check Logz.io for your logs​

Give your logs some time to get from your system to ours, and then open Open Search Dashboards.

You can search for type:wazuh to filter for your logs. Your logs should be already parsed thanks to the Logz.io preconfigured parsing pipeline.

If you still don't see your logs, see Filebeat troubleshooting.
