Automated Security Alert Analysis and Notification Workflow

This n8n workflow serves as an automated Security Operations Center (SOC) analyst, streamlining the process of monitoring, analyzing, and reporting security alerts from a network monitoring system. Scheduled to run daily at 8 AM, it gathers real-time security insights from the Wazuh and NixGuard platforms via an integrated workflow. The process begins with retrieving daily security events, which are then parsed and cleaned from markdown code blocks to extract valid JSON alert data. The workflow employs AI-powered analysis to prioritize alerts into categories such as Critical, High, and Informational. Alerts exceeding a severity level threshold are further filtered for immediate attention. Based on the AI-determined priority, customized Slack notifications are sent to respective channels, ensuring critical issues receive urgent attention while less severe alerts are logged for later review. This automation helps security teams reduce alert fatigue, respond promptly to high-severity threats, and maintain continuous security oversight without manual effort. Practical use cases include daily security health checks, threat prioritization, and automated incident reporting in an environment with extensive security alerts.
