Nexus365 – Microsoft to end support of TLS 1.0 and 1.1 – yeah!

Microsoft has announced that, from the end of October 2018, it will end support of older versions of TLS (Transport Layer Security). TLS is the successor of the deprecated SSL (Secure Sockets Layer) protocol which provides secure connections across networks.

  • Do I use TLS?
    • Yes you do!
  • Where do I use TLS?
    • Whenever you login to a modern website or online service (ie anything with a https web address or login to a smartphone app)
  • So what does this mean for me?
    • Well it means that access to your University email (Nexus365) will only work with the newer TLS 1.2 secure connection – and you need to make sure that your devices and software supports TLS 1.2.
  • Why is Microsoft doing this? What is wrong with the older versions?
    • Well TLS 1.0, 1.1 and SSL3 have been around for a long time (mid 1990s) when the Internet was a more genteel place. Life and the Internet have moved on and these older protocols are just NOT secure enough anymore.

So, in order to connect securely to Nexus365 after October 2018 all browsers and client software must support TLS 1.2 or later.

Here is a selection of known software which does not support TLS 1.2 are listed below:

Software not supported Suggested “fix”
Android 4.3 (and earlier) update to a newer version
Firefox version 5.0 (and earlier) get a newer version of Firefox from
Internet Explorer 8-10 on Windows 7 (and earlier) Use Internet Explorer 11 or the latest versions of  Chrome and Firefox
Internet Explorer 10 on Windows Phone 8.0 you have a Windows Phone? Really?! Use Internet Explorer 11
Safari 6.0.4/OS X10.8.4 (and earlier) update MacOS to a newer version

If you have any device that runs the above software then you will need to update to newer versions.
