Subject: UAWiFi Security Update May 11

Date: May 6, 2019

The University of Arizona Network provides fast, reliable, and secure connections to the internet. TLS (transport layer security) is the internet protocol that protects data from end to end, such as from your phone to a website starting with "https." The oldest version, TLSv1.0, is no longer considered secure and doesn't provide appropriate data protection. To maintain a secure network, TLSv1.0 will be disabled on UAWiFi and eduroam May 11, 2019.


If your laptop, smartphone, or tablet has a current operating system and browser, you should not see any difference. However, there are approximately 13,000 connections across campus that are currently using TLS1.0. As of May 11th, devices currently using TLSv1.0 without the ability to automatically use the more secure protocols will not be able to access the UA's secure wireless networks.

To find out if your device will be affected, open the TLS 1.0 disabled test site.

If you are able to view the site without getting an error, you will see a response that you have passed the test. Your browser is not affected and you do not need to take any further action.

If your device does not automatically begin using a newer version of TLS, you can try:

  • "forgetting" the UAWiFi (or eduroam) network, then re-joining it
  • upgrading your device to the current operating system
  • upgrading your browser to the current version


If you are having issues with network connectivity, contact:

  • Personal devices: contact the 24/7 IT Support Center at (520) 626-TECH (8324).
  • University-owned devices: contact your departmental IT support team.
