Security Information and Event Management (SIEM)

SIEM platforms serve as the central nervous system for security operations, aggregating and analyzing data from across the enterprise:

Key SIEM Capabilities:

  • Log collection and normalization
  • Real-time correlation and alerting
  • Historical analysis and reporting
  • Threat intelligence integration
  • Automated response actions
  • Compliance reporting

SIEM Implementation Best Practices:

  1. Start with High-Value Data Sources: Focus initially on critical systems like domain controllers, firewalls, and authentication systems
  2. Tune for Your Environment: Customize rules and thresholds based on normal behavior patterns
  3. Implement Use Cases Gradually: Begin with high-confidence detections before adding complex correlations
  4. Maintain Data Quality: Ensure consistent logging and time synchronization across sources
  5. Regular Rule Updates: Keep detection logic current with emerging threats

Common SIEM Use Cases:

  • Failed authentication tracking
  • Privileged account monitoring
  • Data exfiltration detection
  • Malware command and control identification
  • Insider threat detection
  • Compliance violation alerting
