Setup

This setup guide will show you how to forward logs produced by PROVE IT to Sekoia.io by means of an Rsyslog transport channel.

On most GNU/Linux servers, two packages need to be installed: rsyslog and rsyslog-gnutls.

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

Configure the rsyslog server

Open or create a new PROVE IT configuration file for rsyslog:

sudo vim /etc/rsyslog.d/46-proveit.conf

Paste the following rsyslog configuration to trigger the emission of Pulse Connect Secure logs by your Rsyslog server to Sekoia.io:

# Define the SEKIOA-IO intake certificate
$DefaultNetstreamDriverCAFile /etc/rsyslog.d/Sekoia.io-intake.pem

# Configure up the network ssl connection
$ActionSendStreamDriver gtls # use gtls netstream driver
$ActionSendStreamDriverMode 1 # require TLS for the connection
$ActionSendStreamDriverAuthMode x509/name # server is authenticated

# Template definition [RFC5424](https://tools.ietf.org/html/rfc5424#section-7.2.2)
# IMPORTANT: don't forget to set your intake key in the template
template(name="SEKOIAIOProveITTemplate" type="string" string="<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG [SEKOIA@53288 intake_key=\"YOUR_INTAKE_KEY\"] %msg%\n")

# Send your events to Sekoia.io intake servers under SEKOIAIOPulseTemplate template
if $hostname == "YOUR_PROVEIT_HOSTNAME" then @@(o)intake.sekoia.io:10514;SEKOIAIOProveITTemplate

In the above template instruction, change the YOUR_PROVEIT_HOSTNAME variable with the correct value, and please replace YOUR_INTAKE_KEY variable with your intake key.

Restart Rsyslog

$ sudo service rsyslog restart

Enjoy your events
