TheHive

In September 2021, StrangeBee announced a change to TheHive’s licensing model and ended support for TheHive version 3 effective December 31, 2021 (see https://medium.com/strangebee-announcements/faq-for-thehive-5s-upcoming-distribution-model-af0ccb95d18). The new licensing model for TheHive version 5 is not compatible with our project so we must say goodbye to TheHive. Starting in Security Onion 2.3.100, we are transitioning from TheHive to Cases. Existing installations with TheHive enabled will still be able to use TheHive and access their existing TheHive data for a very short time. However, new installations will not be able to enable TheHive. We will stop including TheHive container images starting in Security Onion 2.3.120, currently scheduled for release in March 2022. From that point forward, users running the current version of Security Onion will no longer be able to natively run TheHive on the platform and our support for TheHive on Security Onion will end. Users wishing to continue using TheHive on Security Onion should plan to migrate to an external instance of TheHive. For now, users will still be able to escalate events from Security Onion Console to external instances of TheHive version 3.

Documentation is always a work in progress and some documentation may be missing or incorrect. Please let us know if you notice any issues.

New Installations

Existing 2.3 Installations

If you have an existing Security Onion 2.3 installation, please be aware that custom settings in Kibana may be overwritten during upgrade. Also note that this version upgrades to salt 3004 and that process can be complicated. If possible, we recommend that you test the upgrade process on a test deployment before deploying to production. If you have a distributed deployment, then we recommend monitoring SOC Grid while your update is running to verify that all nodes update properly. If there are issues, you can review logs, services, and containers for any additional clues. If you need help, please see our support information below.

For more information about the update process, please see:

Coming Soon in Security Onion 2.3.100!

We hope your 2022 is off to a great start! We're excited for what this year will bring, starting with two major changes coming very soon!

High Availability Pipeline via New Receiver Node

Our customers and community have asked for a high availability pipeline option and so we are happy to announce that Security Onion 2.3.100 will include a new role option called the “receiver node.” This node allows for redundancy in the data pipeline so if for some reason the manager goes down the search nodes can continue to receive data. This also allows for load balancing of external log sources if the manager is overloaded. 

Say Goodbye to TheHive and Hello to Cases!

In September, 2021, StrangeBee announced a change to TheHive's licensing model and ended support for TheHive version 3 effective December 31, 2021:
https://medium.com/strangebee-announcements/faq-for-thehive-5s-upcoming-distribution-model-af0ccb95d18

The new licensing model for TheHive version 5 is not compatible with our project so we must say goodbye to TheHive and Cortex. With the release of Security Onion 2.3.100, existing installations with TheHive enabled will still be able to use TheHive for a very short time. However, new installations will not be able to enable TheHive. We will stop including TheHive and Cortex container images starting in Security Onion 2.3.120, currently scheduled for release in March 2022. From that point forward, users running the current version of Security Onion will no longer be able to natively run TheHive on the platform and our support for TheHive on Security Onion will end. Users wishing to continue using TheHive on Security Onion should plan to migrate to an external instance of TheHive. For now, users will still be able to escalate events from Security Onion Console to external instances of TheHive version 3.

We took this opportunity to re-imagine case management. We started with standard case management features:

• assigning analysts
• defining Severity, Priority, TLP, PAP, Category, and Tags
• robust commenting including markdown support
• adding attachments
• tracking observables

Now what if all of these features were even more tightly integrated into Security Onion Console? What if users could go to the Alerts page and escalate multiple alerts to the same case quickly and easily without having to merge cases? What if they could then pivot to the Hunt interface to find related logs and add those to the same case just as quickly and easily?

We are excited to announce that Security Onion 2.3.100 will include SOC Cases! For more information, please see the screenshot tour below and the documentation at:
https://docs.securityonion.net/en/2.3/cases.html

Stay tuned for Security Onion 2.3.100 and SOC Cases!
