How do I disable network / wifi for guest account in OS X?

Question

I have an OS X machine (Mavericks) that I want to use as a public machine. For this reason I have activated the guest account. However, I can't figure out how to disable the ability for the guest user to connect to Wifi networks (like open networks around). That is, how do I remove or block the ability for guest user to access network settings / enable WiFi?

Solution

Go to System Preferences → Network, select your Wi-Fi service and click Advanced….
Enable Require administrator authorization to: Change networks.

                                           

This will then require the username and password of an administrator on the computer to change wireless network, however this does not prevent an Ethernet connection from overriding the Wi-Fi connection should the Ethernet service have a higher priority (click the gear at the bottom of the service list, then Set Service Order…).
