Modern SIEM is More Than Log Aggregation
Security Information and Event Management (SIEM) systems have evolved significantly. Today's SIEM solutions are comprehensive security platforms that enable proactive threat hunting, automated response, and deep security analytics.
1. Data Sources Beyond Traditional Logs
Modern SIEMs should ingest data from:
Cloud service logs (AWS CloudTrail, Azure Activity Logs)Container orchestration platforms (Kubernetes, Docker)Network flow data (NetFlow, IPFIX)Endpoint Detection and Response (EDR) systemsThreat intelligence feedsApplication performance monitoring2. Use Case Development
Don't just collect logs—develop specific detection use cases:
High Priority Use Cases:
Privilege escalation attemptsLateral movement detectionData exfiltration patternsCredential compromise indicatorsInsider threat behaviors3. Automation and Orchestration
Integrate SIEM with SOAR (Security Orchestration, Automation, and Response):
Automated ticket creationThreat enrichment workflowsAutomated containment actionsResponse playbooks4. Threat Hunting Integration
Use your SIEM as a hunting platform:
Hypothesis-driven investigationsBehavioral analyticsAnomaly detectionHistorical threat analysis5. Performance Optimization
Storage Strategies:
Hot storage (7-30 days): Fast SSD for active investigationsWarm storage (30-90 days): Standard storage for recent dataCold storage (90+ days): Archive for complianceQuery Optimization:
Use indexed fieldsFilter early in queriesLeverage summary indexesCache common searches6. Team Training and Documentation
Your SIEM is only as good as the team using it:
