On our hospital campus we have an "open" wlan that requires the usual

servers using the regular client application. Other than the normal
reasons for keeping everything except 80 and 443 closed, I'm looking to

Is there an authenticated SSID that those staff members should be
using instead? If so, why are they using the open SSID?
Which means I do block access to all authenticated services (Blackboard,
Banner, Mail, etc) on open/guest/conference SSIDs. If they have a
password to use those authenticated services, then they should be using
that same password to connect to the staff/student SSID.
I would say 'no we don't permit that access' and then kindly direct them
to the helpdesk to configure their wireless devices.
