Security Onion 2 Has Reached General Availability (GA)!

In 2018, Security Onion Solutions started working on the next major version of Security Onion, code-named Hybrid Hunter:
https://blog.securityonion.net/2018/11/security-onion-hybrid-hunter-101-tech.html

After 4 Technology Preview releases, 4 Alpha releases, and 3 Beta releases, we dropped the Hybrid Hunter code name and announced 2.0 (RC1), 2.1 (RC2), and 2.2 (RC3). This has been our most ambitious project to date, taking over 34 months and resulting in a whopping 5,034 git commits. Today, we are proud to announce that Security Onion 2.3 has reached General Availability (GA)! 

Changes from Security Onion 16.04

Here are some of the major differences of the new Security Onion 2.3 compared to Security Onion 16.04:

  • Features a new web interface called Security Onion Console (SOC) that includes native alert management, threat hunting, and pcap retrieval
  • Adds TheHive, Strelka, support for Sigma rules, Grafana/InfluxDB (independent health monitoring/alerting), Fleet (osquery management), and Playbook (detection playbook tool).
  • Moves from Ubuntu packages to containers
  • Supports both CentOS 7 and Ubuntu 18.04
  • Changes pcap collection tool from netsniff-ng to Google Stenographer
  • Upgrade to Elastic Stack 7.x and support the Elastic Common Schema (ECS)
  • Completely replaces unsigned kernel module PF_RING with AF_PACKET
  • Suricata completely replaces Snort. (We may elect to add Snort back after Snort 3.0 is officially released.)
  • Removes Sguil, Squert, capME, and PHP
  • Storage Nodes are now known as Search Nodes
  • The first node in a distributed deployment is now called a Manager

Changes from Security Onion 2.2 RC3

If you tried out Security Onion 2.2 RC3, you will notice some changes in this release.

This release features a brand new web interface for alerts. This includes NIDS alerts from Suricata, HIDS alerts from Wazuh, Playbook alerts, and YARA matches from Strelka. This interface is specifically designed to help you triage alerts as quickly as possible. Slice and dice your alerts with multiple views and then pivot to full packet capture or our Hunt interface to investigate IP addresses or other items of interest. Once you've made a determination about an alert, you can either acknowledge it or escalate it to TheHive to create a case.

Next, we've continued to iterate on Hunt, improving its default queries and default pivot actions. Hunt now supports more customization as well.

Finally, we've continued to improve support for airgap deployments. Airgap deployments now include a local copy of the documentation. Also, airgap deployments now support updates using the latest ISO image.

Documentation

We've started migrating our documentation to 2.3:

https://docs.securityonion.net/en/2.3/
