Transport Layer Security (TLS 1.2)

edit

As part of our ongoing effort to provide high levels of security, while maintaining flexibility for browser of choice, Black Knight MLS (BKMLS) will implement necessary security settings to our servers. This is in response to required changes to internet security protocols for Transport Layer Security (TLS).

Starting in November 2015, BKMLS servers will only support TLS v1.2 for secure communications.

What is the impact for Users?

Computers running the following operating systems or browsers will no longer be able to connect to BKMLS systems (e.g. Paragon, PXL, reInsight, etc.) using SSL, which is required during the Agent Login process:

• Windows Vista, Windows 2008 and Windows XP
• Internet Explorer 9 or below, Firefox 26 or below, Chrome 29 or below, Safari 6 or below do not support TLS 1.2 (includes Opera 16 below, if in use, which is not supported by BK MLS for product use)
• MAC using Internet Explorer

Changes to Transport Layer Security (TLS) will be effective November 10, 2015 with Pre-Release and December 2, 2015 for All Customers during the regularly scheduled downtime maintenance window.

What can I do?

Upgrade your computer to the latest version of a preferred but supported operating system. Download and install the latest version of a preferred and supported browser. The majority of modern web browsers like Chrome, Firefox, Safari, and Internet Explorer 10+, already use TLS v1.2.

What does this mean exactly?

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. These underlying technologies help protect sensitive information when you're shopping online, or logging into a password protected site. You may recall there was extensive media coverage of a widespread security vulnerability called POODLE last fall. It made headlines everywhere, and Black Knight MLS made changes to help limit the impact of that issue similar to what we are doing now with TLS.
