Automate Security Incident Response: Crowdstrike, VirusTotal, Jira & Slack Integration
detail.loadingPreview
Streamline your security operations by automatically analyzing Crowdstrike detections, enriching them with VirusTotal intelligence, creating Jira tickets for investigation, and notifying your team via Slack. This workflow ensures faster response times and improved threat management.
About This Workflow
This n8n workflow is designed to automate a critical part of your Security Operations Center (SOC) response. It begins by fetching new detections from Crowdstrike. Each detection is then individually analyzed, with its associated Indicators of Compromise (IOCs) and file hashes being searched within VirusTotal for threat intelligence. The workflow constructs a detailed report of the findings, including malware scores and behavioral analysis, before automatically creating a Jira ticket for further investigation. Finally, a concise notification is posted to Slack, providing your team with immediate awareness and essential details to kickstart their response.
Key Features
- Automated Detection Analysis: Proactively retrieves and processes new security alerts from Crowdstrike.
- Intelligent Threat Enrichment: Leverages VirusTotal to gain crucial context on identified IOCs and files.
- Streamlined Ticketing: Automatically generates Jira tickets with rich details for efficient incident tracking.
- Real-time Notifications: Instantly alerts your team on Slack with key detection and analysis information.
- Customizable Reporting: Consolidates behavioral details and threat intelligence into a structured format.
How To Use
- Connect Your Services: Ensure you have valid credentials configured for Crowdstrike (OAuth2), VirusTotal (API Key), Jira, and Slack within n8n.
- Configure Crowdstrike Trigger: Set up the 'Schedule Trigger' to define how often new Crowdstrike detections should be fetched (e.g., every 15 minutes).
- Map Detection Data: Configure the 'Get recent detections from Crowdstrike' node with the correct API endpoint and filter for 'status:new'.
- Process Detections Individually: Use the 'Split out detections' node to handle each detection separately.
- Extract and Enrich IOCs: The 'Split out behaviours' node extracts behavioral data. Then, the 'Look up SHA in Virustotal' and 'Look up IOC in Virustotal' nodes query VirusTotal using the extracted SHA256 hashes and IOC values.
- Format Incident Details: The 'Set behaviour descriptions' node constructs a detailed markdown string with all relevant information, including links to Crowdstrike and VirusTotal.
- Consolidate Information: The 'Merge behaviour descriptions' node aggregates the formatted details.
- Create Jira Ticket: Configure the 'Create Jira issue' node to generate tickets with a summary derived from the detection's severity and hostname, and the merged descriptions as the ticket body.
- Notify on Slack: Set up the 'Post Slack message' node to send a concise alert to your designated Slack channel, including crucial details about the incident.
