Hello Stefan,
I am sorry for my late reply. Hope you are not too frustrated by little feedback volume. :-)
Thank you very much for putting so much effort into this. I installed the ISO in a virtual machine, but are unfortunately experiencing network troubles, so I did not get any IDS rules downloaded, yet.
The redesigned user interface looks quite nice and is intuitive (as far as I can tell). At the moment, only one minor issue showed up: When downloading IDS rules (or attempting to do so), "snort" is still displayed in the message instead of "IDS" or "suricata".
I will write more details as soon I got the network to work properly.
Thanks again, and best regards, Peter Müller
