Wireless Application Usage

Since wireless networks are by nature insecure (information is passed through the air and thus is susceptible to being captured), OIT requires wireless users to use only secure applications – those that do not send passwords in clear-text. This page will help you make the switch to using secure applications. Don’t worry – all of these changes or new programs will work perfectly (and be more secure!) on the wired network as well. Remember, using Purple Air will also secure you communications over the air.
