The process of relating multiple security event records to gain more clarity than is available from any single record in isolation is called correlation.

Correlation in the context of security event management involves analyzing and combining various security logs and events to identify patterns that might indicate a security incident or threat. This process is a fundamental part of Security Information and Event Management (SIEM) systems, which automate the correlation of events across different security controls and monitoring systems.
