You believe the Dome had public facing websites with admin access enabled that would have the ability to shut down the Dome?

Regarding this? I don't believe anything besides the provided IP's belonging to Rafael in Haifa. Regarding security systems in general? Sure, seen plenty of them. Flabbergastingly stupid setups overlooking very obvious flaws. And I'm not even that skilled.

I have no problems believing that hackers can take down the Iron Dome. If they've done it in this case, I don't know.

It would be the first topic covered in 'Internet Security for Dummies' book.

Is that a thing or are you just making up stuff to support your claim?
