Currently, SafeSync for Enterprise supports TLS 1.0, 1.1, and 1.2. This can be verified using the original SSL protocol value stated in the config file of ngix service.

cat /etc/nginx/conf.d/ssfe.conf
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

To disable TLS 1.0:

  1. Run the following command to remove TLS 1.0 from SSL protocol:

    sudo sed -i 's/TLSv1 //' /etc/nginx/conf.d/ssfe.conf

  2. Confirm the changes in the SSL protocol using the command below:

    cat /etc/nginx/conf.d/ssfe.conf

    The result should be similar to the following:

    ssl_protocols TLSv1.1 TLSv1.2;

  3. Restart the ngix service for the changes to take effect:

    sudo /etc/init.d/nginx restart

  4. Test the new configuration using the SSL Server Test website. This web service deeply analyzes the configuration of any SSL web server on the public Internet.
