The traffic is transferred using TCP port 514 and the content is encrypted, the output of the packet capture for an event:

 

execute tcpdump -i port1 host 10.5.21.115 and port 514 -vX

Event created in FortiNAC:

FNAC event.PNG

 

The same event triggers several syslog being sent in FortiAnalyzer containing extended information that will be used later on the reports:

 

faz logs.PNG

 

On later versions of FortiAnalyzer a Built-in template for FortiNAC is already included that can be run out of the box:

 

run report.PNG

This will generate a nicely formatted report that includes tables and charts that can be viewed as HTML or can be downloaded as PDF.

It will include information about endpoints and network devices that can also be used as a current picture of the network at a given time. It will include the connection status, location, and inventory details of the endpoints also the status of every port in the managed network device.

 

This report can be scheduled to run more frequently, for example, every 4 hours:

Troubleshooting communication:

 

The communication is handled by OFTP which is a Fortinet proprietary protocol. To check the message content of what FortiNAC send to FortiAnalyzer we can enable this debug and check the output master logs as follow:

 

diagnose debug plugin enable OFTPPlugin

 

diagnose tail -F output.master
