Doug Burks has announced the release of Security Onion 2.4.180, an updated build of the project's Linux distribution designed for threat hunting, enterprise security monitoring and log management: "Security Onion 2.4.180 is now available and includes several new features, updated components and many quality-of-life improvements. Cancel your own long-running SOC query - Security Onion can now alert on offline agents, if you run a query in Security Onion Console (Alerts, Dashboards, Hunt) that takes a long time, you now have the ability to cancel your own query by clicking the X on the spinner animation. Enable static hostname mapping without reverse DNS lookups - you can now enable static hostname mappings without having to enable reverse DNS lookups. This release updates several components including Elastic 8.18.6, Suricata 7.0.12, Zeek 7.0.10. The Elastic and Suricata updates resolve security issues so we highly recommend upgrading. In the recent 2.4.170 release, we added a new hypervisor feature for Security Onion Pro customers. This release improves on that by allowing you to run the hypervisor on a manager."

The new release, version 2.4.160, comes with several new alert response tools: "Security Onion 2.4.160 is now available and includes Playbooks and Guided Analysis to help you more quickly triage and respond to alerts. In this release, when you expand an alert you'll see a new tab called Guided Analysis. This leverages Playbooks to show you plays associated with the alert. These plays include questions which help guide your investigation. Each question has an associated query and the results of that query will be automatically displayed to help you answer the question. This release includes a number of hand-written playbooks that are used at the detection engine (NIDS, Sigma, YARA) and category (e.g 'ET MALWARE') level. We have also used AI to generate individual Playbooks for all ETOPEN NIDS rules (58k)." Continue to the release announcement for more information and screenshots.
