secure booting IC and CID should be possible but won't give runtime protection unless they get super fancy

I'd concentrate on the gateway first, the classic "update-from-unsecure-domain" design flaw was really surprising.

you cant close them as long as there needs to be legit traffic and that traffic can be abused.
