How to Retreive Missing/Additional Fields from Check Point using OPSEC LEA?

Path Finder


Trying to work out if 1) Check Point's LEA API does in fact allow the pull of additional fields and 2) how to configure Splunk to get these fields in?

The field I am mainly after is part of the IPS Software Blade (aka SmartDefence) product in the "General Event Information" box in the GUI and the field name is "Follow Up". I can see the other fields above this one been pulled into the start of the logs but not this field. I also see it in a 2011 version of "LEA Fields Update" from Check Point:

--- Page 12

Sample logs which correspond to the attached pic from the GUI:

time=####|loc=#####|fileid=####|action=reject|orig=<blah>|i/f_dir=outbound|i/f_name=eth5|has_accounting=0|uuid=<00000000,00000000,00000000,00000000>|product=SmartDefense|Protection Name=Suspicious Mail Attachment Containing JavaScript Code|Severity=4|Confidence Level=5|protection_id=asm_dynamic_prop_JS_SMTP_ATTACH|SmartDefense Profile=Edge_Recommended_Protection|Performance Impact=3|Industry Reference=None|Protection Type=protection|Update Version=#####|rule=20|rule_uid={00000000,00000000,00000000,00000000}|rule_name=SMTP Delivery - EXT -> DMZ|Attack Info=Suspicious Mail Attachment Containing JavaScript Code|attack=SMTP Protection Violation|src=<blah>|s_port=44555|dst=<blah>|service=smtp|proto=tcp|capture_uuid=<00000000,00000000,00000000,00000000>|__policy_id_tag=product=VPN-1 & FireWall-1[db_tag={00000000,00000000,00000000,00000000};mgmt=<blah>;date=#####;policy_name=Edge]|origin_sic_name=CN=<blah>,O=<blah>

Also should note that the fields in the pic that appear above the highlighted "Follow Up" field mixed with the "Log Info" section at the beginning of the log. So log lengths shouldn't have anything to do with it.

So is this information possible to retrieve or am I wasting time?

You can parse it to a field named e.g. "confidence_level" with this rex:
rex field=_raw "Confidence\sLevel=(?\d)"
