How does a security information and event management (SIEM) system correlate events?

A Security Information and Event Management (SIEM) system correlates data to detect and respond to threats effectively by collecting and analyzing data from various sources such as logs, network traffic, and endpoints. It uses correlation rules to identify patterns and anomalies that could indicate potential security incidents. By normalizing and aggregating data, the SIEM system can provide a holistic view of the organization’s security posture. Automated alerts and responses can be triggered based on predefined criteria, enabling security teams to respond promptly to threats. Additionally, SIEM systems often incorporate machine learning and artificial intelligence capabilities to enhance threat detection and response processes.
