Good Afternoon David, We limit to http, https and vpn for our Guest SSID. The only bandwidth limiting we do is give it the lowest QoS policy out to the Internet. Have a good day, Aaron [Description: Description: Description: logo-email] Aaron Childs, CCNA Associate Director, Networking Information Technology www.westfield.ma.edu/it<http://www.westfield.ma.edu/it> Please Note: new e-mail address - aaron () westfield ma edu<mailto:aaron () westfield ma edu> From: The EDUCAUSE Security Constituent Group Listserv [mailto:SECURITY () LISTSERV EDUCAUSE EDU] On Behalf Of David Curry Sent: Monday, April 29, 2013 10:19 AM To: SECURITY () LISTSERV EDUCAUSE EDU Subject: [SECURITY] Guest wireless restrictions We're (still) in the process of thinking about how we want to split our wireless network into two SSIDs, one for students/faculty/staff and one for "guests" (in quotes because students and staff may be allowed to use it too). We're thinking we want to do what a number of other schools have done, and limit the "guest" SSID to a few protocols: * ICMP * HTTP and HTTPS * POP and IMAP in their SSL flavors only (no plaintext) * SMTP in its SSL and TLS flavors only (no plaintext) * VPN (IPSec, PPTP, L2TP) which after Googling around a bit seems to be a pretty common set (some also allow unencrypted POP/IMAP/SMTP, and others also allow various flavors of chat/instant messaging). We'd also like (we think) to limit individual user bandwidth on the guest wireless, partly to cut down on the damage a "misbehaving" client can cause, and partly to encourage students/faculty/staff to move over to the "secure" SSID. Googling around on this topic, I've been able to find lots of schools doing this, but very few that document what their limits actually are. So, two questions: 1. If you limit the protocols on your guest wireless, is there anything not in the list above that you've found it necessary to allow? 2. If you limit the bandwidth (speed) on your guest wireless, what are your download/upload limits (speeds), and what does that allow/not allow (e.g., streaming audio/video). Thanks, --Dave -- DAVID A.
