Common Event Format
ArcSight's Common Event Format (CEF) is an open log management standard. If one of your applications or devices is not covered by one of the other intakes we support but can produce logs in CEF you can use this intake.
Still we recommend using an intake tailored to your specific application or device, even with CEF, in order to ensure you get the most out of your logs. If an intake is missing, please contact us.
This setup guide will show you how to forward your CEF logs to SEKOIA.IO by means of an rsyslog transport channel. On most linux servers, two packages need to be installed: rsyslog and rsyslog-gnutls.
1. Download the certificate
In order to allow the connection of your rsyslog server to the SEKOIA.IO intake, please download the SEKOIA.IO intake certificate:
$ wget -O /etc/rsyslog.d/SEKOIA-IO-intake.pem https://app.sekoia.io/assets/files/SEKOIA-IO-intake.pem
2. Configure the Rsyslog server
Open or create a new configuration file for rsyslog:
sudo vim /etc/rsyslog.d/xx-yyyyy.conf
Customize the following rsyslog configuration to trigger the emission of logs by your rsyslog server to SEKOIA.IO.

In the above
template instruction, please replace
YOUR_INTAKE_KEY variable with your intake key.
3. Restart rsyslog
$ sudo service rsyslog restart
4. Enjoy your events
Go to the events page to watch your incoming events.
