How to correlate Splunk alerts with Indicators Of Compromise (IOC)?

Based on the following Splunk Alert I am trying to trace back to an IOC.

rt=Jul 18 2018 02:47:29 UTC dvchost=fireeye-a12bc3 categoryDeviceGroup=/IDS categoryDeviceType=Forensic Investigation categoryObject=/Host cs1Label=Host Agent Cert Hash cs1=AbCDEfG12hijklMnopQ

cs5Label=Target GMT Offset cs5=PT0H cs6Label=Target OS cs6=Windows Server 2012 R2 Standard 9600 externalId=34 start=Jul 18 2018 02:46:58 UTC categoryOutcome=/Success categorySignificance=/Compromise 
categoryBehavior=/Found cs7Label=Resolution cs7=ALERT cs8Label=Alert Types cs8=exc act=Detection IOC Hit msg=Host WIN-12AB3c4DE5F IOC compromise alert categoryTupleDescription=A Detection IOC found a compromise 
indication. cs4Label=IOC Name cs4=FIREEYE END2

The goal is to gather as much information from the Splunk alert, (IOC's ids/URL/Domain Name etc) and send it to Swimlane and have it available to pull any additional data necessary from FireEye.
