Cattle Bank & Trust will be officially retiring TLS 1.0 security protocol support on all of our services in order to align with industry best practices and ensure that your data continues to be highly secure.
TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network.
On May 1, 2018 we will disable the TLS 1.0 encryption protocol, which may prevent you who still use it from using some or all of your online and mobile banking functionality. This means that you may need to upgrade your browsers to disable TLS 1.0 and use TLS 1.1 or higher, but this change will not affect you in any other way.
Check if your browser has already disabled TLS 1.0 by visiting this website https://tls1test.salesforce.com/.
Frequently Asked Questions
Q: What is TLS?
A: TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network. TLS ensures that a connection to a remote endpoint is the intended endpoint through encryption and endpoint identity verification. The versions of TLS, to date, are TLS 1.0, 1.1 and 1.2.
Q: What is the change, when is it happening and how does this impact me?
A: An upgrade to TLS 1.1 or higher will begin on May 1, 2018. On that date, we will
begin disabling the TLS 1.0 encryption protocol, which may prevent you from accessing some or all of our online banking services.
Browsers and mobile operating systems may need to be upgraded.
Please reference the information below for browser versions that support TLS 1.1. and higher. If you are using a browser version that is lower than those listed below, they may not be able to access some or all of their online banking services.
- Microsoft Internet Explorer (IE): version 11 and higher
- Microsoft Edge – all versions
- Mozilla Firefox: version 27 and higher
- Google Chrome version 38 and higher
- Apple Safari
- Desktop Safari: versions 7 and higher for OS X 10.9 (Mavericks) and higher (7)
- Mobile Safari: versions 5 and higher for iOS 5 and higher
Users operating on Android version KitKat (4.4) and lower, which includes about 20% of the U.S. population according to current usage patterns, may be impacted by the disablement of TLS 1.0 as
these versions do not support TLS 1.1 and 1.2. Upgrading to Lollipop (5.0) or higher will fix this issue and support TLS 1.1 and 1.2.
Q: Why are we doing this?
A: TLS aims to provide privacy and data integrity between two communicating applications. TLS 1.1 and above provide significantly higher security controls than TLS 1.0. Protecting our customer’s data is of the utmost importance for us, and this disablement will allow us to better ensure the security of your data. Our goal is to make this process as seamless as possible while maintaining the highest security standards.
Q: Am I ready to upgrade to TLS 1.1 or higher?
A: You can use this website https://www.howsmyssl.com/ to check your version of TLS. Look under the Version heading for your current TLS version.
Q: What happens if end users don’t upgrade their browsers or mobile systems in time?
A: On the May 1, 2018 cut-off date, all systems will be changed so TLS 1.0 traffic will be redirected to a page that will say “Stronger Security is Required.” The message might be in the browser window or it might appear in the tab of the browser as seen below. The “Stronger Security is Required” page was implemented to ensure a secure connection to your banking application was enforced. Screenshots of the message on a browser and mobile application are below. The browser message will look the same no matter what browser the end user is on.
