Choosing your Ciphers Suites to enhance security


TLS/SSL, the security behind HTTPS, can use several different algorithms to secure, encrypt and authenticate a connection.

The choice of the algorithm to use is decided by an agreement between the server and the client, depending on which algorithms are available on each side.

A cipher suite is a named combination of authentication, encryption, message authentication and key exchange algorithms.

Terminal Service Plus server can handle a lot of different ciphers suites. Some of them are more secure than others, but some old/legacy browsers might require relatively weak algorithms to connect.

This is the reason why Terminal Service Plus let you choose the ciphers suites you want to enable. Of course, Terminal Service Plus also has an easy setting to disable the weakest algorithms, thus enhancing your connections security.

Ciphers Selection GUI

To open Terminal Service Plus Ciphers Selection GUI, open Terminal Service Plus AdminTool, click on „Security“, then click on „SSL Ciphers Selection“ as shown in the screenshot below:

The Ciphers Selection GUI will open, as shown in the screenshot below:

Enabling/Disabling a Cipher Suite

You can easily enable a cipher suite by checking its checkbox, and disable a ciper suite by unchecking it.

When your selection is done, click on „Save“.

This will save your selection and reload the new configuration in Terminal Service Plus built-in web server. Your new ciphers suites selection is instantly applied for every new connection to your server.

Recommended Ciphers Suites Selection

We recommend to most administrator to use our recommended ciphers suites selection, by simply clicking on the „Disable weak ciphers“ button and then the „Save“ button.

This action will disable all ciphers suites which are currently known to be weak.

You can check with SSL Labs Online Testing Tool: without those weak ciphers suites you should get the maximum grade: A!
