Just make sure NetworkManager isn't installed in your live image.
Then, there's no way a normal user can initiate a network connection.
They'd have to manually configure the classic network service or yum
install NetworkManager, both of which require root.

The other solutions just make it slightly more complicated for root to
restore network access and don't really add any additional security.

Security is nonexistent here anyway, since your user could just boot
their own live image, mount your live image within it, and either
change the root password or re-enable network access directly from a
chroot.  If you don't control the hardware, no software security
measure in the world can help you.
