SELKS is a free and open source Debian-based IDS/IPS/Network Security Monitoring platform released under GPLv3 from Stamus Networks (https://www.stamus-networks.com/).
SELKS can be installed via docker compose on any Linux or Windows OS. Once installed it is ready to use out of the box solution.
SELKS ISOs are also available for air gapped environment or bare metal or VM installation.

SELKS is comprised of the following major components:
The acronym was established before the addition of Arkime, EveBox and CyberChef.
And it includes preconfigured dashboards like this one:

SELKS is a showcase of what Suricata IDS/IPS/NSM can do and the network protocol monitoring logs and alerts it produces. As such any and all data in SELKS is generated by Suricata:

The usage of Suricata data is further enhanced by Stamus' developed Scirius, a threat hunting interface. The interface is specifically designed for Suricata events and combines a drill down approach to pivot for quick exploration of alerts and NSM events. It includes predefined hunting filters and enhanced contextual views:

An example subset (not complete) of raw JSON logs generated by Suricata can be found here <https://github.com/StamusNetworks/SELKS/tree/master/doc/example-logs>_.
If you are a new to Suricata, you can read a series of articles we wrote about The other side of Suricata <https://www.stamus-networks.com/blog/the-other-side-of-suricata>_.
SELKS has by default over 28 default dashboards, more than 400 visualizations and 24 predefined searches available.
Here is an extract of the dashboards list: SN-ALERTS, SN-ALL, SN-ANOMALY, SN-DHCP, SN-DNS, SN-DNP3, SN-FILE-Transactions, SN-FLOW, SN-HTTP, SN-HUNT-1, SN-IDS, SN-IKEv2, SN-KRB5, SN-MQTT, SN-NFS, SN-OVERVIEW, SN-RDP, SN-RFB, SN-SANS-MTA-Training, SN-SIP, SN-SMB, SN-SMTP, SN-SNMP, SN-SSH, SN-STATS, SN-TLS, SN-VLAN, SN-TFTP, SN-TrafficID
Additional visualizations and dashboards are also available in the Events viewer (EveBox).
The minimal configuration for production usage is 2 cores and 9 Gb of memory. As Suricata and Elastisearch are multithreaded, the more cores you have the better it is. Regarding memory, the more traffic to monitor you have, the more getting some extra memory will be interesting.
You can spin up SELKS on any Linux or Windows OSes in minutes via docker compose. See Docker Installation <https://github.com/StamusNetworks/SELKS/wiki/Docker>_.
For air gapped environement or full OS installation, see SELKS ISO Setup <https://github.com/StamusNetworks/SELKS/wiki/Docker-ISO-setup>_.
You need to authenticate to access to the web interface(see the HTTPS access section below ). The default user/password is selks-user/selks-user (including through the Dashboards or Scirius desktop icons).
You can change credentials and user settings by using the top left menu in Scirius.
Default OS user:
selks-userselks-user (password in Live mode is live)The default root password is StamusNetworks
If you wish to remotely (from a different PC on your network) access the dashboards you could do that as follows (in your browser):
You need to authenticate to access to the web interface. The default user/password is the
same as for local access: selks-user/selks-user. Don't forget to change credentials at first
login. You can do that by going to Account settings in the top left dropdown menu of
Scirius.

While SELKS is suitable as a production network security solution in small to medium sized organizations and is a great system to test out the power of Suricata for intrusion detection and threat hunting, it was never designed to be deployed in an enterprise setting. For enterprise applications, please review our commercial solution, Stamus Security Platform (SSP).
Stamus Security Platform (SSP) is the commercial network-based threat detection and response solution from Stamus Networks. While it retains much of the same look and feel as SELKS, SSP is a completely different system and requires a new software installation.
Available in two license tiers, SSP delivers:
