  • Ah, well done!

    Reminded me of the time I finally got some scans of old Belgian comics and they had diagonal stripes all through them, a common artifact of scanning at the time.

    The answer was using imagemagick and fast Fourrier transforms to isolate the stripes and filter them out! Led me down an awesome rabbithole of math and digital imaging I still haven’t recovered from.

    Running suricata on your wan interface is just generating a ton of noise and will be really confusing for you if you haven’t reviewed packet inspection alerts before. Not a lot of value in it unless you have many users “phoning home”.

    Just run it on the lan interface.

    Your approach of deny all until something complains is pretty much the most solid way to get a grip on security.

    I assess and recommend security practices for a living, and I would say the most important first step is understanding where your data lives and where it goes. Once you know that, the rest is relatively easy with the tools available to us.
