detail.loadingPreview
This n8n workflow provides an automated, AI-enhanced system for daily cyber threat intake, risk evaluation, and vulnerability triage. It fetches the latest CVEs and IOCs, assesses their criticality, and automatically sends alerts and logs high-priority threats, ensuring prompt response and compliance alignment.
About This Workflow
This powerful n8n workflow, "CYBERPULSEBlueOps_Module1," revolutionizes your organization's threat intelligence and vulnerability management. Operating daily, it seamlessly integrates external CVE and IOC feeds, simulating an AI-driven engine to assess and prioritize cyber risks. Vulnerabilities are intelligently triaged into "expert review," "self-healing," or "monitoring" categories based on calculated risk scores. For critical threats, the system triggers immediate email alerts to your security team and logs comprehensive details into Google Sheets, providing an auditable record. Designed with compliance in mind, it aligns with frameworks like ACSC Essential Eight and ISM, bolstering your security posture and operational efficiency.
Key Features
- Automated Daily Threat Intelligence: Automatically fetches the latest Common Vulnerabilities and Exposures (CVEs) and Indicators of Compromise (IOCs) daily.
- AI-Enhanced Risk Evaluation: Simulates AI logic to assign dynamic risk scores (
aiRisk,lev) to vulnerabilities, offering deeper insights beyond standard CVSS. - Intelligent Vulnerability Triage: Categorizes threats into "Expert Review" (critical), "Self-Healing" (high), and "Monitoring" (low) for streamlined incident response.
- Instant Critical Alerting: Automatically sends detailed email notifications to your security team upon detection of critical, expert-triaged vulnerabilities.
- Compliance-Aligned Logging: Logs comprehensive threat data, including CVE ID, severity, LEV scores, and compliance tags, to Google Sheets for auditing and tracking, adhering to standards like ACSC E8 and ISM.
