This is an integration for parsing Common Event Format (CEF) data. It can accept data over syslog or read it from a file.
CEF data is a format like
CEF:0|Elastic|Vaporware|1.0.0-alpha|18|Web request|low|eventId=3457 msg=hello
When syslog is used as the transport the CEF data becomes the message that is contained in the syslog envelope. This integration will parse the syslog timestamp if it is present. Depending on the syslog RFC used the message will have a format like one of these:
<189> Jun 18 10:55:50 host CEF:0|Elastic|Vaporware|1.0.0-alpha|18|Web request|low|eventId=3457 msg=hello
<189>1 2021-06-18T10:55:50.000003Z host app - - - CEF:0|Elastic|Vaporware|1.0.0-alpha|18|Web request|low|eventId=3457 msg=hello
In both cases the integration will use the syslog timestamp as the @timestamp
unless the CEF data contains a device receipt timestamp.
The Elastic Agent's decode_cef processor is applied to parse the CEF encoded
data. The decoded data is written into a cef object field. Lastly any Elastic
Common Schema (ECS) fields that can be populated with the CEF data are
populated.
This module will process CEF data from Forcepoint NGFW Security Management
Center (SMC). In the SMC configure the logs to be forwarded to the address set
in var.syslog_host in format CEF and service UDP on var.syslog_port.
Instructions can be found in KB
15002 for configuring
the SMC.
Testing was done with CEF logs from SMC version 6.6.1 and custom string mappings were taken from 'CEF Connector Configuration Guide' dated December 5, 2011.
This module will parse CEF data from Check Point devices as documented in Log Exporter CEF Field Mappings.

There are cases where incoming CEF messages do not follow the CEF specification exactly, and this can cause errors with message decoding. To work around this, there is an option for pre-processors, which are run before the CEF message is decoded. These can be used modify the message to follow the CEF specification correctly, which will allow proper decoding.
The pre-processors will modify the message field before CEF decoding is done on the agent, but the original, non-preprocessed,
message will still be preserved in the event.original field when the agent sends the event.
This is the CEF log dataset.
An example event for log looks as following:
