Our outsourced IT department has decided to use white listing on the firewalls

CentOS 5 or 6 with a smattering of 7. It is impractical to list all the
possibilities since they change on a regular basis. Also any 3rd party repos
we need are another ball of wax.
Various Google searches and the manual page have not shown me how to avoid
using ftp mirrors. I have considered taking out the ftp-proxy information so
that the ftp cannot get out, but I suspect it will just hang waiting for a
response.
Does anyone have any suggestions on ways to tell yum not to use ftp as the
download mechanism?
Thank you in advance.

FWIW, my Centos 7 install doesn't have ftp installed and yum has no
apparent issues.
I also, mainly, use Fedora (22 currently) and it hasn't had ftp
installed for a long time. Of course it uses dnf now, not yum.
AFAIK yum and its successor dnf uses "libcurl" for the transfer, which
has "curl" as cli.
curl and wget both can use the ftp:// protocol, so the (non-)presence
of "ftp" is not a deciding factor.
Setting up a proxy that gives a "404"/deny on ftp:// is more helpful here.
