There are instances when customers need to disable SSL versions (1.0, 2.0, and 3.0) and TLS 1.0 to comply with their security policy. As an alternative, customers can change those protocols to TLS 1.1 and 1.2.
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:
- Run the following command to remove TLS 1.0 from SSL protocol:
sudo sed -i 's/TLSv1 //' /etc/nginx/conf.d/ssfe.conf
- Confirm the changes in the SSL protocol using the command below:
The result should be similar to the following:
ssl_protocols TLSv1.1 TLSv1.2;
- Restart the ngix service for the changes to take effect:
sudo /etc/init.d/nginx restart
- 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.
