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
The Ubuntu used in this tutorial:
root@LTS-64-1:~/opt#uname -a

If you have these packages installed you need to remove them so that Scirius would work with the latest python dependencies.
Please be careful so that this actually does not affect your current running services. It is always best to test first 🙂
root@LTS-64-1:~/opt#apt-get remove django-tables python-django python-django-south python-git
Install the needed dependencies:

Now lets have a walk through registering and adding a ruleset
For example (for the latest stable and dev Suricata) from http://rules.emergingthreats.net/open/suricata/emerging.rules.tar.gz since Emerging Threats create, write and distribute specially tuned for Suricata rulesets that make use of the advanced features of that IDS engine.
First we need to add a source:
Then we add a ruleset:
We need to edit the ruleset and select the categories we want from that ruleset:
Select categories:
Validate changes:
If you have already Elasticsearch, Logstash, Kibana installed on the same server,
you could do the following -> put in the values as on the picture – except the host name – chose the hostname to be exactly as your hostkey in Elasticsearch/Kibana , like in the pics below.
Then in Scirius ->
Now you should be able to see the hits and which rules are making the most noise 🙂
That’s it for a quick intro.
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.
I’ve given a talk entitled “Suricata 2.0, Netfilter and the PRC” at the Hackito Ergo Sum conference.
The talk is presenting Suricata and the new features available in version 2.0, focusing on the new EVE output and how it can be used with Elasticsearch, Logstash and Kibana. I’ve also shown how ulogd, the Netfilter logging daemon can be used with Elasticsearch thanks to the new JSON output plugin. Finally, I’ve explained how I’ve discovered a attack schema which is originating from systems running in the People Republic of China.
