LRN to Stop Support of TLS 1.0 Protocol

LRN will no longer support TLS 1.0 protocol, which will be disabled on LRN’s Catalyst® Platform on March 3, 2019 at 6:00 AM (PST)/2:00 PM (GMT)

Frequently asked questions (FAQ)

What is TLS 1.0 Protocol?

TLS stands for “Transport Layer Security” version 1.0. This protocol is used to establish a secure connection between the user’s browser and a website.

Why are we halting support and disabling TLS 1.0 Protocol?

TLS 1.0 has been identified as the root cause of many high-risk security vulnerabilities. To ensure that the highest security standard is delivered and maintained by LRN’s Catalyst® platform, we decided to disable support for TLS 1.0 in order to avoid any of the security risks that have been reported.

What is the expected impact?

TLS 1.0 protocol is used by Internet Explorer (IE) Version 7 on Windows XP and Vista (also with IE 7). Access to the LRN’s Catalyst® platform via these combinations of browser and operating systems will no longer be supported and will result in an error.

What you should do?

LRN recommends that you reach out to your Information Technology and/or Security teams to assess any impact this will have on your users and implement an appropriate mitigation solution.

Does this change impact other browsers?

The table below list the main Operating Systems (OS) and the Browser versions supported.


What are the changes required in IE 8, IE 9 or IE 10 to ensure continued support?

To ensure IE 8, 9 and 10 will continue to work on LRN’s Catalyst® platform, TLS 1.1 and TLS 1.2 must be enabled on these browsers. To enable TLS 1.1 and TLS 1.2, the end-user should follow the instruction below: 

  • Open Internet Explorer
  • From the menu bar, click Tools > Internet Options > Advanced tab.
  • Scroll down to the Security group, check the option box for Use TLS 1.1 and Use TLS 1.2.
  • Click OK.
  • Close Internet Explorer and restart it.
