Enhanced Security for Online Banking Access

May 1, 2017

On May 15, 2017, the First National Bank of Northfield will disable TLS 1.0 and 1.1 to maintain the highest standards for your data security and best practices. If you use one of our online banking products, personal or business, you will need to verify that you have a compatible operating system (OS) and browser.  Please refer to the chart below for compatible operating systems and browsers.

If your operating system and browser state that they are compatible by default in the chart below, there is nothing that you need to do.  You already have the necessary security request in place.

Operating Systems and Browsers TLS 1.2 Compatibility
Microsoft Windows Server 2008 R2 and higher Compatible by default
Microsoft Windows Server 2008 and below Not compatible with TLS 1.2
Microsoft Windows 7, 8.0, 8.1 and 10 Compatible by default
Microsoft XP\Vista and below Not compatible with TLS 1.2
Microsoft Edge Compatible by default
Microsoft IE Desktop and mobile version 11 Compatible by default
Microsoft IE Desktop versions 9 and 10 Compatible when run in the Windows 7 or newer, but not enabled by default
Firefox 27 and higher Compatible by default
Google Chrome 38 and higher Compatible by default
Mobile Safari versions 5 and higher Compatible by default

Failure to ensure that your systems are compatible will result in an interruption in your online banking access.

What is Transport Layer Security (TLS) protocol? This protocol is an industry standard designed to protect the privacy of information communicated over the Internet. TLS assumes that a connection-oriented transport, typically TCP, is in use. The TLS protocol allows client/server applications to detect the following security risks:

  • Message tampering
  • Message interception
  • Message forgery
