Event Correlation: SIEM analyzes and correlates events from different logs to identify patterns and anomalies that might indicate a security breach.
Real-time Threat Detection: SIEM provides real-time visibility into an organization’s security posture, allowing security teams to detect threats as they occur.
Incident Response: SIEM can generate alerts and automate responses to detected threats, enabling faster incident response and containment.
Historical Analysis: SIEM can also provide historical analysis of security events, which is crucial for incident investigation and root cause analysis.

Benefits of Using SIEM System

Enhanced Threat Detection: SIEM helps organizations detect threats early on, preventing them from escalating and causing significant damage.
