Kibana¶

From https://www.elastic.co/kibana:

Kibana is a free and open user interface that lets you visualize your Elasticsearch data and navigate the Elastic Stack. Do anything from tracking query load to understanding the way requests flow through your apps.

Authentication¶

We support Elastic authentication via so-elastic-auth. Elastic authentication is automatically enabled for new installations, so you will need to log into Kibana using the same username and password that you use for Security Onion Console (SOC).

Dashboards¶

Once you log into Kibana, you should start on the Security Onion - Home dashboard.

Notice the visualization in the upper left is labeled Security Onion - Navigation. This navigation panel contains links to other dashboards and will change depending on what dashboard you’re currently looking at. For example, when you’re on the Security Onion - Home dashboard and click the Alert link, you will go to the Security Onion - Alerts dashboard and the Navigation panel will then contain links to more specific alert dashboards for Playbook, Suricata, and Wazuh. When you’re done looking at alerts, you can click the Home link in the navigation panel to go back to the main Security Onion - Home dashboard.

We’ve included the old 16.04 dashboards in case you performed an in-place upgrade and have any old 16.04 data. These dashboards are named with the z16.04 prefix and will only show old 16.04 data from the old *:logstash-* indices. The new Security Onion 2 dashboards are all named with the Security Onion prefix and they should be used for any new data stored in the new *:so-* indices.

If you ever need to reload dashboards, you can run the following command on your manager:

sudo so-kibana-config-load

If that doesn’t resolve the issue, then you may need to run the following:

sudo salt-call state.apply kibana.so_savedobjects_defaults -l info queue=True

If you try to modify a default dashboard, your change will get overwritten. Instead of modifying, copy the desired dashboard and edit the copy. You may also want to consider setting up Kibana Spaces as this will allow you to make whatever changes you want without them being overwritten. This includes not only dashboards but certain Kibana settings as well. You can read more about Kibana Spaces at https://www.elastic.co/guide/en/kibana/current/xpack-spaces.html.

Pivoting¶

Kibana uses multiple hyperlinked fields to accelerate investigations and decision-making:

PCAP/Cases¶

The _id field has a hyperlink which is labeled as Hunt and optionally pivot to PCAP/Cases. Clicking this hyperlink takes you to Hunt and searches for that particular record. From Hunt, you can then escalate the event to Cases or pivot to full packet capture via our PCAP interface (assuming it’s a network event). You can usually find the _id field as the rightmost column in the log panels at the bottom of the dashboards.

You can also find the hyperlinked _id field by drilling into a row in the log panel.

Indicator Dashboard¶

Several fields are hyperlinked to the Indicator dashboard to allow you to get all the information you can about a particular indicator. Here are just a few:

uid
source.ip
source.port
destination.ip
destination.port

Search Results¶

Search results in the dashboards and through Discover are limited to the first 100 results for a particular query. If you don’t feel like this is adequate after narrowing your search, you can adjust the value for discover:sampleSize in Kibana by navigating to Stack Management -> Advanced Settings and changing the value. It may be best to change this value incrementally to see how it affects performance for your deployment.

Timestamps¶

By default, Kibana will display timestamps in the timezone of your local browser. If you would prefer timestamps in UTC, you can go to Management –> Advanced Settings and set dateFormat:tz to UTC.

Configuration¶

Kibana’s configuration can be found in /opt/so/conf/kibana/. However, please keep in mind that most configuration is managed with Salt, so if you manually make any modifications in /opt/so/conf/kibana/, they may be overwritten at the next salt update.

/opt/so/conf/kibana/etc/kibana.yml can be managed using the kibana pillar placed in the manager pillar file located under /opt/so/saltstack/local/pillar/minions/. The manager pillar file will end with either *_manager.sls, *_managersearch.sls, *_standalone.sls, or *_eval.sls depending on the manager type that was chosen during install.

An example of a Kibana pillar may look as follows:

kibana:
  config:
    elasticsearch:
      requestTimeout: 120000
    data:
      autocomplete:
        valueSuggestions:
          timeout: 2000
          terminateAfter: 200000
    logging:
      root:
        level: warn

Diagnostic Logging¶

Kibana logs to /opt/so/log/kibana/kibana.log. Depending on what you’re looking for, you may also need to look at the Docker logs for the container:

sudo docker logs so-kibana

If you try to access Kibana and it says Kibana server is not ready yet even after waiting a few minutes for it to fully initialize, then check /opt/so/log/kibana/kibana.log. You may see something like:

Another Kibana instance appears to be migrating the index. Waiting for that migration to complete. If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_6 and restarting Kibana

If that’s the case, then you can do the following (replacing .kibana_6 with the actual index name that was mentioned in the log):

curl -k -XDELETE https://localhost:9200/.kibana_6

sudo so-kibana-restart

If you then are able to login to Kibana but your dashboards don’t look right, you can reload them as follows:

so-kibana-config-load

Features¶

You can enable or disable specific features by clicking the main menu in the upper left corner, then click Stack Management, then click Spaces, then click Default. For more information, please see https://www.elastic.co/guide/en/kibana/master/xpack-spaces.html#spaces-control-feature-visibility.
