iOS 10 gives hints about how to make Hampshire wireless networks more secure. What’s that about?
If you have a device that runs iOS 10 you may have noticed that it offers hints for improving the security of wireless networks, in particular Hampguest, Wallace, and Gromit, but not for Eduroam. There’s nothing you need to do to improve the security, but all of us should understand the basics of the security issue so we can make the best choice.
Limiting Access to Wireless Networks
There are ways to limit who is allowed to connect using wireless networks. At Hampshire we limit access to the Wallace (faculty and staff) and Gromit (student) networks by requiring a Hampshire account be entered to register each device used on those networks; Hampguest is open for the public to use while on campus. This helps us keep our IT infrastructure somewhat protected, as well as helping to keep wireless traffic within our capacity.
Wireless Network Data Security
What simply controlling access to a wireless network does not do is to encrypt the information that you send over the wireless network. Data that is not encrypted is vulnerable to being intercepted by a nearby hacker. Keep in mind, though, that information you send to secure http sites (web addresses that start with “https”), as well as our email system (and hopefully any current email system), are encrypted by protocols enforced by those systems.
Wireless networks that are encrypted protect the information you send from your computer so that an eavesdropping computer cannot decipher them. There are different methods of encrypting, with a WPA2 encryption method being the current standard.
Eduroam is the Encrypted Wireless Network on Campus
Of the Hampshire wireless networks, only Eduroam provides this encryption protection. We strongly recommend that the Hampshire community use Eduroam whenever possible. Eduroam does provide access to file servers and printing for faculty and staff, but there are Hampshire web services that are not currently available on Eduroam; if you run into problems accessing a service, try switching to Wallace to see if it works.
We are planning to eventually discontinue Wallace and Gromit, and switch entirely to Eduroam. It is a good idea to set up Eduroam sooner rather than later, not only to take advantage of its security features, but also because it is available at many other educational institutions.
