Secure Socket Layer (SSL) is an encryption-based Internet security protocol for establishing secure links between a server and a client. It provides privacy, authentication, and integrity to Internet communications. SSL:
- Authenticates users and servers, ensuring that data is sent to the correct clients and servers.
- Encrypts data to prevent it from being intercepted during transfer.
- Ensures data integrity during transmission
SSL is disabled for new DDM instances by default. Enabling SSL increases CPU usage and makes it take a little longer to establish a network connection, so you are advised to evaluate these impacts on service performance before enabling SSL.
You can connect to a DDM schema through a client using an SSL or non-SSL connection.
- If SSL is enabled, you can connect to a DDM schema using an SSL or non-SSL connection. SSL encrypts connections to the DB instance, making in-transit data more secure.
- If SSL is disabled, you can only connect to a DDM schema using a non-SSL connection.
Enabling or disabling SSL will cause instances to reboot and interrupt connections. Exercise caution when performing this operation.
Enabling SSL
- On the Instances page, locate the instance that you want to connect to and click its name.
- On the Basic Information page, at the Instance Information area, click
in the SSL field. - In the displayed dialog box, click Yes.
- On the Basic Information page, view the results. Click
next to the SSL field to download the CA certificate.You can use SSL to connect to a schema. For details, see Step 4: Log In to the DDM Schema.
Disabling SSL
- On the Instances page, locate the instance that you want to connect to and click its name.
- On the Basic Information page, at the Instance Information area, click
in the SSL field. - In the displayed dialog box, click Yes.
- On the Basic Information page, view the results.
