Thanks to the EVE JSON events and alerts format that appear in Suricata 2.0, it is now easy to import Suricata generated data into a running Splunk.

To ease the first steps of integration, Stamus Networks is providing a Splunk application: Suricata by Stamus Networks

It can be installed like any other applications and it just requires that a Suricata EVE JSON file is known and parsed by Splunk.

Current version is providing a dashboard and a few searches:

This post describes how to import the application and if you don’t have already done it how to import data from a Suricata EVE file.

Importing the application

Importing the application is done via the Apps menu on top of Splunk starting page:

Suricata by Stamus Networks application is currently provided as a file, so you need to download it: Suricata by Stamus Networks. Once done, you can add the application:

You need to select the file

Importing a Suricata EVE JSON file

Since splunk 6.1.x, the recognition of the file format is automatic. If you are using an older version of Splunk, you may need to refer to this page to import Suricata EVE file.

Here’s the detailed procedure to import Suricata EVE data into Splunk. From the starting page, we click on Add Data:

Then we click an Files & Directories to tell Splunk to import data from Suricata EVE JSON file:

Once done, we click on the New button:

Now, we only need to give the complete path to the eve.json file:

Once this is done, we just need to click on all Continue buttons to be done.

Using the application

Now, we can go to the application by clicking on Suricata by Stamus Networks:

Next step can be to to go the dashboard:

The dashboard contains some interesting panels like the following one who displays the destination IP addresses that are using a self-signed certificate for TLS connections:

Conclusion

This application should evolve with time, so stay tuned and follow us on twitter for more information.

Stamus Networks is proud to announce the release of SELKS 1.0 beta2. This is the second public release of our Live and installable ISO implementing a ready to use Suricata IDS/IPS.

SELKS 1.0 beta2 can be downloaded:

• Via torrent: SELKS-1.0beta2.iso.torrent (preferred method)
• Via HTTP: SELKS-1.0beta2.iso.

MD5 sum of the SELKS-1.0beta2.iso file is 38222aeda399f7502913c91465ac9499.

If this new release features some improvements in the creation process, the main new things for the user are an updated version of Scirius and a custom Kibana interface. A menu to switch from one interface to the other has been added on both application. A link has been added in the detail of alert event to be able to jump from Kibana to the correct place in Scirius rule management. The following screencast demonstrates these features:

On Suricata side, file extraction and Unix socket are now enable by default. So SELKS 1.0-beta2 will extract to disk files from stream if signatures containing the filestore are used. The activation of Unix socket allows user to get data from Suricata and/or to use alternate running modes like multiple pcap processing.

The complete Changelog is as follows:

• bump ES to 1.2.1
• suricata: enable file extraction
• kibana: use stamus version
• suricata: enable unix-socket
• scirius: remove unused files
• build: add capability to add option to lb config
• scirius: use new command to build default ruleset (Fix Issue 1)
• scirius: use version 0.4
• doc: update links on desktop README

Stamus Networks is proud to announce the release 0.3 of Scirius, our web interface for Suricata ruleset management.

The interface has been redesigned for more compacity and clarity:

Two major features have been added:

• Support of local rules: User can now upload rules contained in an archive
• Fast suppression of rules: two clicks are enough to suppress one rule

It is now also possible to select the time period selection on rules activity:

Please note, the rules with sid 220029 on the screenshot. It is displayed strikethrough because it has been suppressed from the ruleset.

Here’s a screencast showing how easy it is to suppress a noisy rule from a ruleset:

With all these new features, we think that Scirius can now be efficiently used to administrate a Suricata ruleset.

Stamus Networks is happy to release Scirius as Open Source Software under GPLv3. You can download it from GitHub : scirius-0.3.tar.gz.

Stamus Networks is proud to announce the first release of Scirius, its Suricata ruleset web management interface.

Scirius is a web management interface developed by Stamus Networks and released under the GPLv3 license. The interface is aiming simplicity and efficiency and that’s why we have adopted a simple design:

It is possible to link Scirius with a running Elasticsearch fed by Suricata EVE JSON log. Once done, information stored in the Elasticsearch can be used to get an idea of the activity of the Suricata. The following screenshot is an example of statistics fetched from Elasticsearch and displayed in Scirius:

Scirius is currently in alpha stage but it is already possible to manage efficiently a Suricata ruleset using ETOpen or ETPro ruleset. For example, the following video is demonstrating how it is possible to remove a selected subset of signatures from the ruleset:

Scirius is available on Github. Following releases of Scirius will feature among other things the support for local signatures (uploaded by the user) and some missing operations such as quick removal of individual signature.
