I'm not sure exactly what you mean here, but I have counter examples for
|
|
two possible interpretations.
|
|
|
|
If you mean that no one in your experience is worried by unencrypted
|
|
access from local IP addresses, then we certainly are especially for
|
|
wireless users.
|
|
|
|
If you mean that no one in your experience enables unencrypted access from
|
|
local IP addresses, then I believe it's fairly common for universities to
|
|
do so to avoid having to reconfigure thousands of desktop clients. It
|
|
took us about a year to completely disable unencrypted access - we wanted
|
|
to avoid huge spikes in support load.
|
|
|
|
With the right software it's fairly easy to restrict unencrypted logins to
|
|
local wired networks.
|
|
