Gen7 - doing a lot of (unnecessary) DNS requests

BWCBWC Cybersecurity Overlord ✭✭✭

While being annoyed about the current reboot loop dilemma on Gen7 I needed a distraction and examined what kind of DNS requests a factory reset Gen7 Appliance is doing when just running idle or only accessed via Management UI.

I know clean coding is not much of a thing these days and SNWL is no exception to that, but it looks we could easily skip a bunch of DNS requests here and there. It's a plain TZ 670 with no current services at the moment. Essential Security got expired.

The good (AFAIK): (~every 120 seconds, registration for older firewalls, LOL) (according to KB this is the licensemanager for newer firmware) (~every 150 seconds) (~every 60 seconds, for whatever reason)

This should be updated?

The bad: (is this the internal NTP when not configured?) (this is a parked domain, for real?) (this is a parked domain, for real?)

The ugly: (was licensed, not active, but expired) (never had Endpoint licensed) (~every 90 seconds, never had Endpoint licensed) (~every 60 seconds, never had Endpoint licensed) (Client CF not licensed) (not documented) (not documented) (~every 60 seconds, never had Endpoint licensed) (never had Endpoint licensed) (never had Endpoint licensed) (~every 150 seconds, CDP? For real, isn't that EOL for ages) (never had Endpoint licensed)

It's probably just me because I'am somewhat older, but avoiding unnecessary requests always looked like a good thing to me. I would like to see my firewall keeping the own activities to a minimum and keep focus on it's purpose.

Maybe this can be addressed somehow in case anybody cares.

    @BWC it's not good that you have too much time 🤔

    that's why you get teased with updates and loops and curiosities. don't look into the canned...

    the floor is not yet in sight
