Doug Burks has announced the availability of and updated build of Security Onion, a specialist Linux distribution designed for threat hunting, enterprise security monitoring and log management. 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.
