SIEM Best Practices: Building an Effective Security Monitoring Program

A Security Information and Event Management (SIEM) system is the cornerstone of modern security operations centers (SOCs). When properly implemented and maintained, a SIEM provides comprehensive visibility into your security posture, enabling rapid threat detection and response.

Understanding SIEM Fundamentals

What is SIEM?

SIEM combines Security Information Management (SIM) and Security Event Management (SEM) into a unified platform that:

• Collects and aggregates log data
• Correlates events across sources
• Detects security incidents
• Generates alerts and reports
• Supports compliance requirements
