Should suricata be monitoring traffic on green interface

Was moving a file from a local Windows machine to a Samba share on the NS server:

Suricata usage plummeted to almost nothing when the copy ended.

Is there a way to make Suricata only monitor the red interface.


Hello @EddieA,

I think it’s necessary to listen to the green interface, because you won’t see which LAN device is infected for instance if you only listen on red. Interfaces are defined in /etc/suricata/suricata.yaml.

There is another discussion about suricata on LAN or WAN or both:
