Security Onion: analyzers

Security Onion 2.3.130 is now available! It includes new features and resolves a few issues:
https://docs.securityonion.net/en/2.3/release-notes.html#changes

Dashboards

Security Onion 2.3.130 now includes a new Dashboards app!

The new Dashboards app includes an entire set of pre-built dashboards for our standard data types.

In addition to the pre-built dashboards, you can make your own dashboards very quickly and easily:

create a data table for a particular field using the action menu or by manually typing in a "groupby" option in the query bar

add additional fields to that data table OR a new data table
convert the data table(s) to a pie chart, bar chart, or Sankey diagram using the buttons in the Count column

Here's what it looks like in action!

If you're familiar with our Hunt interface, then you'll feel right at home in Dashboards. The main difference between Hunt and Dashboards is that Dashboards has a different set of default queries that give you one dashboard for each data type, providing a simplified experience. Also, the new capabilities of creating multiple data tables and converting to charts or diagrams carries over to Hunt to make your hunting that much more powerful!

Analyzers

This release also includes analyzers allowing you to quickly gather context around an observable. Analyzers can leverage multiple internal and external sources of data without ever having to leave SOC!

For example, let’s start by going to the OBSERVABLES tab inside of a case. From the screenshot below, we can see we are working with an observable of type hash and a value of 8a62d103168974fba9c61edab336038c. To start analysis for this observable, we click the lightning bolt icon to the left of the observable creation date. At this point, an analyzer job is enqueued for each analyzer that supports the hash data type and results will be returned once all analyzers have completed their analysis.

Here, we can see results for analysis against a local file, Team Cymru’s Malware Hash Registry, Alienvault OTX, Pulsedive, and VirusTotal. All of these analyzers were initiated automatically since they support the hash observable type.

Each analyzer will have a brief description of the outcome of the analysis, such as No results found, Further investigation needed, or Malicious. We can expand the details for each analyzer to find more information. For example, here are the malwarehashregistry and virustotal sections.

In addition to the hash data type, several other types are supported by analyzers, including domain, ip, url, and more – even ja3!

If the supported data types don’t fit your needs, you can use the localfile analyzer. This will allow you to leverage multiple CSV files if desired, utilizing a data type of other and providing threat intel or other associative information that could contribute to overall context.

In addition to the included analyzers, you can also write your own custom analyzers in Python if you need to leverage other data sources or perform analysis in a different manner.

Here’s what the analyzers feature looks like in action!
