Correlation Searches in Splunk Enterprise Security

Correlation Search is basically a saved search running on a schedule that can search across multiple sources of data in the Splunk Environment, these correlation searches are targeted to detect malicious events/patterns. Whenever a correlation search matches the specified criteria/condition/events it can trigger one or more of the available “Adaptive Response Actions”, the most common of which is creating a notable event which surfaces the results on the Incident review dashboard for further investigation and analytics.

Splunk Enterprise Security offers 60 out of the box correlation searches, spanning through the various security domains like access, identity, network, endpoint, threat intelligence etc., depending upon the data that you have on your Splunk platform you can enable one or more of these correlation searches. These correlation searches pull the data from different CIM data models present in Splunk.
