Sigma Rule Coverage Explorer Released

In our habitual spirit of transparency and openness, we have released a web app that lets you see exactly which Sigma detection signatures are supported in uberAgent ESA’s Threat Detection Engine.

TL;DR: take a look at uberAgent Sigma Rule Coverage Explorer.

What is uberAgent Sigma Rule Coverage Explorer?

As we explained in this recent blog post about v2 of our Sigma integration, we’re going to great lengths to make Sigma signatures available for uberAgent ESA’s Threat Detection Engine via a backend plugin for Sigma’s rule converter. We’re working hard to get to supporting 100% of Sigma’s feature set. To document our progress, we’ve developed the Sigma Rule Coverage Explorer app so that everybody can see where we stand.

Why Sigma?

Sigma is the leading open detection signature project. It excels with its open signature format that allows security researchers and analysts to describe their detection methods in a generic, vendor-agnostic manner. Sigma is also a growing repository of peer-reviewed detection and hunting rules that can be converted to a variety of backends.

Why a rule coverage explorer app?

One part of the answer is openness. We believe that, in the long term, it benefits everybody involved to be able to determine a product’s capabilities easily. We’re proud of what we have to offer, and we like to show the cool things uberAgent can do. But we’re not in the business of selling the (non-existent!) one product that does it all. Transparency FTW.

The other part, we’re not ashamed to admit, is selfishness. The Rule Coverage Explorer app has a section that lists the fields not yet supported by uberAgent, along with the number of Sigma rules making use of such fields. This statistic is very helpful for us in determining which features to add to our query language uAQL next.
