Security Onion 2.3.60 now available!

Last October, we released Security Onion 2.3:

Today, we are releasing Security Onion 2.3.60, which adds new features and resolves a few issues:

UPDATE 2021/07/02 10:11 AM - We've identified a few issues in this release and are working on releasing a hotfix. If you haven't already updated to 2.3.60, you may want to wait until we release the hotfix.

UPDATE 2021/07/02 11:34 AM - We've released the hotfix as 2.3.60-ECSFIX. If you had already updated to 2.3.60 via soup, you will want to run soup again to get 2.3.60-ECSFIX. If you had downloaded the 2.3.60 ISO image, you will want to download the new 2.3.60-ECSFIX ISO image.


Starting in Security Onion 2.3.60, we will support Elastic authentication. This means that you will authenticate to Elasticsearch and Kibana using the same username and password that you use for Security Onion Console (SOC). Please make sure you read and understand the following:


We now support official Filebeat modules:

Security Onion Console (SOC)

SOC has many improvements in this release:

  • The Alerts and Hunt pages have consolidated options into a new Options drop-down menu.
  • The Alerts and Hunt pages allow you to do a quick drilldown in some scenarios by clicking the value in the Count column.
  • The PCAP page allows you to select text with your mouse and then select where to send that text (for example, CyberChef) via context menu actions.
  • You can now manually change your timezone.


In this release, Grafana will have both high-resolution data and downsampled low-resolution data. Some Grafana graphs have dotted lines (trend lines) that show previous data that has been downsampled. High-resolution data will be purged after 30 days, leaving just the downsampled low-resolution data.

When upgrading an existing installation to Security Onion 2.3.60, Grafana will not show old data by default. You can update the data as shown here:


We covered some of these highlights in a YouTube video:
