Eduroam: removal of TLS 1.1 protocol

 

What is TLS 1.1?

TLS is a method of encrypting data that “scrambles” data from one service to another, meaning any attempts to “read” it during the movement of the data are stopped.

Sometimes referred to as SSL,  TLS provides a means of keeping data safe, often used in financial systems but really anything that requires keeping secure. TLS 1.1 has been retired.

 

What’s happening?

In order to ensure the security of the University’s systems and services, we will be disabling the TLS 1.1 protocol on the eduroam Wi-Fi service on 31 August 2021. This change will affect any older devices that are not able to support TLS 1.2, including computers running Windows 7 and mobile devices running older versions of iOS and Android.

The TLS 1.1 protocol is not as secure as the newer TLS 1.2 and is no longer supported for connections to many services, including Microsoft’s Office 365. As Windows 7 is no longer supported by Microsoft since January 2020, security patches are no longer available, and we advise that anyone using Windows 7 upgrades to Windows 10.
