Error in CEF format for Threat logs

L3 Networker

The following guide provides the parsing for CEF-style Log Formats for PAN-OS 9.1:

https://docs.paloaltonetworks.com/content/dam/techdocs/en_US/pdf/cef/pan-os-91-cef-configuration-gui...

 

We have been using this for a while, but because now we have a 2nd source of logs (PRISMA) aside from Panorama, we just found out the parsing suggested for "Threat" log is not correct in our opinion, and that was causing some issues on our SIEM use-cases.

 

In short, this field is wrong and should be replaced by $subtype:

 

Threat CEF:0|Palo Alto
Networks|PAN-OS|$sender_sw_version|$threatid|$type|$number-of-severity|rt=$cef-formatted-receive_time
deviceExternalId=$serial src=$src dst=$dst sourceTranslatedAddress=$natsrc

PanOSDGl2=$dg_hier_level_2 PanOSDGl3=$dg_hier_level_3 PanOSDGl4=$dg_hier_level_4
PanOSVsysName=$vsys_name dvchost=$device_name PanOSSrcUUID=$src_uuid PanOSDstUUID=$dst_uuid
PanOSTunnelID=$tunnelid PanOSMonitorTag=$monitortag PanOSParentSessionID=$parent_session_id

  • How can we get this fixed in the document?
  • Additionally, is it possible to get the document updated with PAN-OS 10 in here?
