Simple Intelligence Collector

Overview​

Welcome to the simple intelligence collector workshop! In this lab, you'll build a streamlined threat intelligence collection service that demonstrates essential security automation patterns.

What You'll Build​

A production-ready Intelligence Collector that:

  • Multi-source threat intelligence aggregation - Fetch from multiple threat feeds simultaneously
  • Whitelist-first security - Built-in protection for essential infrastructure
  • Clean API design - RESTful endpoints for integration with other systems
  • Real-time visibility - Simple status page to monitor operations
  • Production-ready patterns - Error handling, data validation, and monitoring

Architecture Overview​

Multiple Feeds → Intelligence Collector → Whitelist Filter → KV Storage

  Raw Data          Enriched Data       Safe Lists      Production Ready

Key Learning Objectives​

By the end of this phase, you'll understand:

  1. Multi-Source Data Aggregation - How to collect and merge data from multiple threat intelligence feeds
  2. Conflict Resolution - Handling duplicate and conflicting threat intelligence data
  3. Whitelist-First Security - Implementing safety mechanisms to prevent false positives
  4. Production API Design - Creating robust, well-documented APIs for service integration
  5. Error Resilience - Building services that gracefully handle failures
  6. Real-time Monitoring - Creating visibility into your security automation

Core Design Principles​

1. Multi-Source Intelligence Aggregation​

  • Fetch from multiple threat intelligence feeds simultaneously
  • Handle different data formats (plain text, CSV, JSON APIs)
  • Implement source reliability weighting (trusted sources get higher scores)
  • Graceful degradation when individual sources are unavailable

2. Conflict Resolution & Data Quality​

  • Automatic deduplication across all sources using IP as primary key
  • Additive scoring system where multiple sources increase confidence
  • Source attribution tracking (which feeds flagged each IP)
  • Data freshness validation to avoid stale threat intelligence

3. Whitelist-First Security Philosophy​

  • Whitelist always overrides threat intelligence (safety first)
  • Built-in protection for essential infrastructure (Cloudflare IPs)
  • Support for custom business-critical IP ranges
  • Audit trail for all whitelist additions and removals

4. Production-Ready API Design​

  • RESTful endpoints with consistent JSON responses
  • CORS support for browser-based integrations
  • Clear error handling with actionable error messages
  • Built-in API documentation via status page

Time Allocation​

  • Total Duration: 45 minutes
  • Project Setup: 5 minutes
  • Core Implementation: 25 minutes
  • Testing & Validation: 15 minutes

Success Metrics​

After completing this phase, you'll have:

  • ✅ A working multi-source threat intelligence collector
  • ✅ Whitelist protection preventing false positives
  • ✅ A simple status page showing real-time data
  • ✅ Clean APIs for integration with other systems
  • ✅ Understanding of conflict resolution between threats and whitelists

What Makes This "Simple" Yet Effective​

This streamlined implementation focuses on core essentials:

  • Multi-source aggregation from trusted threat intelligence feeds
  • Intelligent scoring based on source reliability and overlap
  • Whitelist protection to prevent blocking critical infrastructure
  • Clean API design with proper error handling and pagination
  • Automated scheduling for regular threat intelligence updates
