Automated Email Threat Detection and Case Management
detail.loadingPreview
Streamline your security operations by automatically processing incoming emails, enriching them with threat intelligence, and creating detailed cases for investigation. This workflow enhances your ability to respond to emerging threats.
About This Workflow
This n8n workflow revolutionizes email-based threat analysis. It begins by ingesting emails from an IMAP account, then leverages TheHive to create structured security cases. Attached files are automatically submitted to Cortex for advanced analysis, identifying potential indicators of compromise (IOCs) such as malicious domains, emails, and IP addresses. Based on the analysis results, the workflow dynamically updates the case with relevant IOCs. Furthermore, it triggers specialized analyzers like 'Email Reputation' and 'OTX IP' to gather deeper context on observed observables. This comprehensive approach ensures that your security team has all the necessary information to efficiently investigate and mitigate email-borne threats.
Key Features
- Automated Email Ingestion: Continuously monitor and process emails from your IMAP server.
- Intelligent Case Creation: Automatically generate detailed security cases in TheHive based on email content and attachments.
- Advanced Threat Intelligence: Integrate with Cortex to analyze attachments and extract IOCs.
- Dynamic IOC Enrichment: Populate cases with identified domains, emails, and IP addresses for quick reference.
- Automated Reputation Analysis: Utilize specialized analyzers for email and IP reputation lookups.
How To Use
- Configure IMAP Credentials: Connect your IMAP account to the 'IMAP Email' node to allow n8n to fetch emails.
- Set up TheHive Integration: Configure your TheHive API credentials for the 'TheHive' nodes.
- Integrate Cortex Analyzer: Ensure your Cortex API credentials are set up and that the specified analyzers ('CORTEX' for general analysis, 'Email Reputation', 'OTX IP') are available and correctly configured.
- Define Case Promotability: The workflow automatically promotes incoming emails as cases. Review the 'Create Case' node if you need to adjust any default settings.
- Map and Enrich IOCs: The 'Update Case Domain', 'Update Case Email', and 'Update Case Ip' nodes are pre-configured to extract and add IOCs. The 'Analyzer Email' node executes the initial analysis on attachments.
- Monitor Analysis Results: The 'IF' node acts as a conditional gate, and subsequent 'Update Case' nodes add IOCs. The 'Wait' node provides a buffer before further analysis.
- Execute Reputation Lookups: The 'Email Reputation' and 'OTX IP' nodes trigger targeted analysis on discovered observables.
