Enabling or Disabling SSL
=========================

**Scenarios**
-------------

DDS allows you to use SSL to encrypt connections to a DB instance to protect your data.

-  If SSL is enabled, you can connect to a DB instance using SSL. For details, see sections about connecting to a DB instance using SSL over public or private networks in this document.
-  If SSL is disabled, you can connect to the DB instance using an unencrypted connection. For details, see sections about connecting to a DB instance using an unencrypted connection over public or private networks in this document.

.. important::

   -  For security purposes, disabling SSL is not advised.
   -  Enabling or disabling SSL will cause DB instance restart. Exercise caution when you perform this operation.
