Security Update for Security Onion 2.0 RC1

We recently released Security Onion 2.0 RC1:

https://blog.securityonion.net/2020/07/security-onion-20-release-candidate-1.html

Some community members quickly reported some issues (including 2 security issues) and we've released fixes:

Security Fix 1067: variables.txt from ISO install stays on disk for 10 days

https://github.com/Security-Onion-Solutions/securityonion/issues/1067

Security Fix 1068: Remove user values from static.sls

https://github.com/Security-Onion-Solutions/securityonion/issues/1068

Issue 1059: Fix distributed deployment sensor interval issue allowing PCAP

https://github.com/Security-Onion-Solutions/securityonion/issues/1059

Issue 1058: Support for passwords that start with special characters

https://github.com/Security-Onion-Solutions/securityonion/issues/1058

Thanks to Max Diorio and Reddit user TungstenCLXI for reporting these issues!

UPDATE 2020/07/23 4:53 PM
Looks like the sensor interval fix for distributed deployments introduced a regression for other installation types. We're working on this issue now:
https://github.com/Security-Onion-Solutions/securityonion/issues/1089

UPDATE 2020/07/24 12:14 PM
We've fixed the regression in 2.0.2:
https://blog.securityonion.net/2020/07/security-onion-202-rc1-available-for.html

Existing Installations

If you have an existing 2.0 RC1 installation, you'll want to run "sudo soup" as soon as possible. soup will then update itself and ask you to run soup again. On the second run, soup will update salt and your Docker images. Salt will then remove variables.txt and update static.sls.

Please note that Docker images may still show 2.0.0 (instead of 2.0.1) as they have simply been re-tagged.

For more information, please see the soup page on our documentation site:

https://docs.securityonion.net/en/2.0/soup.html

New Installations

If you're doing a new installation and you download our ISO image, you'll get the new 2.0.1 ISO image that already contains these fixes. 

Otherwise, if you install a standard CentOS7 or Ubuntu 18.04 ISO and then perform a network installation, you'll get the latest code that contains the fixes.

For more information, please see the download page on our documentation site:

https://docs.securityonion.net/en/2.0/download.html

securityonion-sostat - 20120722-0ubuntu0securityonion133 now available for Security Onion!

securityonion-sostat - 20120722-0ubuntu0securityonion133 is now available for Security Onion!  This package resolves the following issue:

securityonion-sostat: block docker 19.03.3 packages #1652
https://github.com/Security-Onion-Solutions/security-onion/issues/1652

Docker 19.03.3 was released recently and included a regression for the DOCKER-USER iptables chain:
https://blog.securityonion.net/2019/10/docker-package-issues-please-do-not.html
https://github.com/docker/for-linux/issues/810

When you install this updated securityonion-sostat package, it will prevent any future installation of Docker 19.03.3.  It will also check to see if you already have Docker 19.03.3 installed.  If so, it will provide instructions for removing Docker 19.03.3 and replacing it with a fixed version.  Any future runs of soup will check Docker version as well.

Thanks

Security Onion Users Can Now Switch to Elastic Features

Many folks have asked if they could switch from the open source version of the Elastic Stack to the Features version licensed under the Elastic license.  You can try it out starting today!

Instructions

• First, please review the Elastic Features license:
  https://github.com/elastic/elasticsearch/blob/6.7/licenses/ELASTIC-LICENSE.txt
• Next, you should make sure that all updates have been installed:
  sudo soup
• If soup prompts to reboot, please do so.  
• Verify that everything is working properly before continuing.
• Edit /etc/nsm/elasticdownload.conf using your favorite text editor and change DOCKERHUB from "securityonionsolutions" to "securityonionsolutionselas":
  DOCKERHUB="securityonionsolutionselas"
• Run soup again to download the new Docker images for Elastic Features:
  sudo soup
• Once soup has downloaded the new Docker images, it should restart your Docker containers.
• Kibana should now have some new features on the left side.

Screenshots

Kibana now includes new features on left side

Q&A

Is Elastic Features open source?

No, it is not open source.  It is licensed under the Elastic license:
https://github.com/elastic/elasticsearch/blob/6.7/licenses/ELASTIC-LICENSE.txt

What does this mean for Security Onion licensing?

Security Onion continues to be free and open source and will continue to default to the open source version of the Elastic Stack.  If you choose to switch to Elastic Features (not open source), you may do so using the instructions above.

If I switch to Elastic Features, is this a trial license?

If you switch to Elastic Features, you can remain on the BASIC license for free forever or you can choose to upgrade to a paid subscription. For more information about Elastic Features subscription levels, please see:
https://www.elastic.co/subscriptions

How does authentication work?

Authentication works the same way it does in our existing Elastic open source images.  Security Onion provides Single Sign On (SSO) using the same username and password for Sguil, Squert, and Kibana.

What about the recent Elastic announcement about security features?

Elastic recently announced that security features are included for free in the Elastic Features license starting in version 6.8.0.  Since Security Onion still uses Elastic 6.7.2, those security features are not free in that version.  We will begin the process of working towards Elastic 6.8.0.
