I'm trying to understand some Fortinet firewall logs but I'm not sure I fully understand what is being logged by the firewall when it comes to direction (Incoming vs Outgoing)
For example:
srcip=7.7.7.7 dstip=192.168.10.50 srcport=45845 dstport=80 srcintf="port5" srcintfrole="wan" dstintf="port10" dstintfrole="lan" proto=6 direction="outgoing"
I'm not sure why that would be categorized as outgoing instead of incoming. Since the traffic appears to be initiated from an external source. Would it not be incoming traffic? Or is it because the last interface is it hits is the LAN interface and it's "outgoing" from there?
The idea is i want to alert on SIEM level for IPS detections initiated by internal devices not comming from the external wan !!
Please anyone can help in that!!

Hello Lonis23i,
The direction field in the IPS logs is not to be mistaken with the direction or flow of the traffic.
The IPS log include the direction
field to show the attack direction not the direction of traffic.
You can refer to the below documentation for more information:

Hope this helps!
