TLS 1.2 Requirement
Transport Layer Security (TLS) is the most widely deployed security protocol used today for Web browsers and other applications that require data to be securely exchanged over a network.
You passively use it whenever you open a browser, and as long as you adhere to the OS/Browser requirements, you should have no browser related issues.
Below is a list of other frameworks, defining their minimum version levels to be TLS 1.2 compliant:
- Java: use Java 8 or later. Java 7 may be used but requires TLSv1.2 to be explicitly enabled by the application
- .NET: use .NET 4.6 or later.
- .NET 4.5 may be used but requires TLSv1.2 to be explicitly enabled by the application.
- .NET depends on TLS 1.2 support by the Windows OS it runs on
- For applications using OpenSSL: use OpenSSL 1.01 or later
- Adobe Reader 9.0 or later for documents secured with AES 128-bit encryption or lower
- Adobe Reader 10 or later for documents secured with AES 256-bit encryption
If you explicitly whitelist IP addresses on your network, please add the below IP ranges to your firewall:
If your organization whitelists IP addresses to control connection to your inbound mail servers, add the following IP addresses to your whitelist:
