CEF module
editCEF module
editThis is a module for receiving Common Event Format (CEF) data over Syslog. When
messages are received over the syslog protocol the syslog input will parse the
header and set the timestamp value. Then the
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.
Read the quick start to learn how to configure and run modules.
Configure the module
editYou can further refine the behavior of the cef
module by specifying
variable settings in the
modules.d/cef.yml
file, or overriding settings at the command line.
You must enable at least one fileset in the module. Filesets are disabled by default.
Variable settings
editEach fileset has separate variable settings for configuring the behavior of the
module. If you don’t specify variable settings, the cef
module uses
the defaults.
For advanced use cases, you can also override input settings. See Override input settings.
When you specify a setting at the command line, remember to prefix the
setting with the module name, for example, cef.log.var.paths
instead of log.var.paths
.
log
fileset settings
edit-
var.syslog_host
-
The interface to listen to UDP based syslog traffic. Defaults to
localhost
. Set to0.0.0.0
to bind to all available interfaces. -
var.syslog_port
-
The UDP port to listen for syslog traffic. Defaults to
9003
Ports below 1024 require Filebeat to run as root.
-
var.tags
-
A list of tags to include in events. Including
forwarded
indicates that the events did not originate on this host and causeshost.name
to not be added to events. Defaults to[cef, forwarded]
. -
var.timezone
-
IANA time zone name (e.g.
America/New_York
) or fixed time offset (e.g.+0200
) to use when parsing times from the CEF message that do not contain a time zone.Local
may be specified to use the machine’s local time zone. Defaults toUTC
.
Forcepoint NGFW Security Management Center
editThis 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.
Check Point devices
editThis module will parse CEF data form Check Point devices as documented in Log Exporter CEF Field Mappings.
