Let’s examine Enabling TLS 1.2 on Plesk in more detail. As part of our Plesk Hosting Support Services, Bobcares provides answers to all of your questions.

Enabling TLS 1.2 Plesk: A step-by-step method

Plesk is a web hosting and server data center automation software. It is developed for Linux and Windows-based retail hosting service providers. Plesk’s licensing options are as follows:

• Plesk Web Admin Edition allows us to manage up to ten domains. It is for basic website care. No other tools and features are needed.
• Plesk Web Pro Edition allows us to manage up to 30 domains. It includes Plesk WordPress Toolkit with full features.
• Plesk Web Host Edition supports an unlimited number of domains. The administrator can add reseller accounts.

TLS provides communications security over a network. We must use the latest TLS versions on the Plesk VPS. This is due to security reasons. And these days, SSL was widely replaced by TLS.

Enabling TLS 1.2 through Dashboard

1. Firstly, log in to the Plesk account.
2. Now go to Tools & Settings >> Scheduled Tasks.
3. Then click the ‘Add Task’ option at the top left.
4. Select ‘Run a command’. Then enter the below code in the textbox near to ‘Command’ option. Click ‘Run Now.’

   /usr/local/psa/bin/server_pref -u -ssl-protocols 'TLSv1.1 TLSv1.2'

    
5. Finally, we will see a message confirming TLS completion.

Enabling TLS 1.2 through CLI

1. We can use the command line or the VPS console to connect to the VPS.
2. Now we can easily disable TLS1.0.  And specify which versions we want to use (server-wide command):

   plesk bin server_pref -u -ssl-protocols 'TLSv1.1 TLSv1.2'

    
3. Finally, we must set Apache to use the TLS 1.2 cipher list. We can use the -ssl-ciphers option to enable specific ciphers. We can also select the ciphers which we need.

   plesk bin server_pref -u -ssl-ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256'

    

These steps enable TLS 1.2. And it disables TLS 1.0.
