Sure. That's because you should never "just connect" to a IEEE 802.1X
network. You configure the security properties you expect *first* (i.e.
install/mark as trusted the CA, the expected server name, the EAP types
that are supposed to be supported on this network, an anonymous outer
identity if you like/need) - and *then* you actually connect, and see if
the server you arrived at is the one you expect.

This is a wholly different security model that website-certificate-TLS.

I've been in touch with the NOC earlier about this. The IETF network
website really needs to *publish* these expected security details, then
you need to *configure* them - and only then is the network secure, and
guaranteed to be the genuine IETF one.

There are also tools which generate installation programs for these
security properties so that unsuspecting users don't have to know or
realise what this "CA" thing is in the first place.

I run a website which does these things; and am perfectly fine with
handing out installers with digital signatures for the IETF network use.

If you're curious hop over to https://802.1x-config.org (and
particularly the "Take the tour" for explanations:
https://802.1x-config.org/tour1.php

Thanks for listening to this slightly ad-laden mail. :-)

Greetings,

Stefan Winter
