Arcsight Compatible ESA Syslog Template

Blog Post created by Eric Partington Employee on Nov 8, 2018

A couple of clients have asked about a generic ESA template that can be used to alert into Arcsight for correlation with other sources.  After some testing and configuration this was the template that was created.  One thing that had us stuck for a short period of time was the timezone offset in the FreeMarker template to get Arcsight to read the time as UTC and apply the correct time offset.

 

Hopefully this helps others with this need.

This CEF template is added to the Admin > System > Global Notifications > Templates tab and referenced in the ESA rules that need to alert out to Arcsight when they fire.
