Which log analysis step involves the use of the correlating key?

The log analysis step that involves the use of a correlating key is “log correlation.”

Log correlation is the process of relating or connecting data from multiple log sources to identify patterns and relationships. A correlating key is a common identifier (such as a user ID, IP address, session ID, etc.) that is used to link related log entries across different log files and sources. This step is crucial in piecing together events from disparate sources to form a coherent picture of what’s happening across a network or system. It is essential in detecting complex multi-step threats, understanding the scope of incidents, and aiding in forensic investigations.
