Highlights

This release includes our new Intrusion Detection Honeypot (IDH) node! You can learn more about that here:
https://docs.securityonion.net/en/2.3/idh.html

Another highlight of this release is Multi-Factor Authentication (MFA) and you can learn more about that at:
https://docs.securityonion.net/en/2.3/mfa.html

We've put a substantial amount of effort into improving the Elastic backend in this release:

• full Elastic Common Schema (ECS) data type compliance, which includes changes for our Hunt queries and Kibana dashboards
• legacy index templates have been replaced with composable index templates, comprised of multiple component templates that define field mappings and other settings
• Zeek DNS logs now go to a separate so-zeek_dns index
• reworked the process for loading ingest pipelines, Elasticsearch templates, and Kibana dashboards to be faster and more resilient
• renamed some field names:
• ingest.timestamp --> event.ingested
• dns.answers --> dns.answers.name
• syslog.facility --> syslog.facility_label
• syslog.severity --> syslog.severity_label

Finally, this release also updates many components including:

• Elastic 7.17.1
• FleetDM 4.10.0
• Grafana 8.4.1
• Kratos 0.8.2-alpha.1

Known Issues

TheHive

As a reminder, 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 April 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.

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. 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.
