Security Information and Event Management (SIEM) Integration

SIEM systems serve as the central nervous system for security monitoring, aggregating logs from diverse sources and providing unified visibility. However, effective SIEM deployment requires more than just log collection. Proper parsing, normalization, and enrichment transform raw logs into actionable intelligence. Custom detection rules and correlation logic must balance comprehensive coverage with manageable alert volumes.

Log retention policies must consider both security and compliance requirements. While longer retention enables historical investigation and trend analysis, it also increases storage costs and potential exposure if logs contain sensitive data. Tiered storage strategies can balance these concerns, keeping recent logs in hot storage for real-time analysis while moving older logs to cheaper cold storage.
