Use SSL with your Cloud Databases instance
Secure Sockets Layer (SSL), a security protocol that uses encryption technology to ensure that sensitive information sent over the Internet is protected, enables users of a website to divulge personal information, such as credit card numbers, Social Security numbers, user names, and passwords, safely. By making an SSL connection to your database, customers can trust that their data is encrypted when it’s sent to and from your web application.
Note: Using SSL encryption is resource-intensive and might impact the latency of your database connection.
Download the CA certificate
Cloud Databases configures your database instance to support the use of SSL when the instance is provisioned. To encrypt data in transit by using SSL, your database connections need to use an SSL certificate associated with Cloud Databases.
Download one of the following SSL certificates, based on when the Cloud Databases instance was created:
For instances created before March 1, 2016, download the SSL certificate from the following URL:
For instances created on or after March 1, 2016, download the SSL certificate from the following URL:
Your applications should use the downloaded certificate as the Certificate Authority (CA) certificate for SSL connections to your database.
Use the certificate with the mysql client
To make SSL connections by using the
mysql command line client, execute the following command to specify
the location of the certificate when you start the client:
You can find more information about using SSL with MySQL® in the MySQL 8.0 documentation.
Require SSL connections
You can restrict a user to require SSL when
communicating with the database. MySQL supports the
REQUIRE SSL. For example, to restrict
database_user to have
read, write, and delete permissions for
prod_database only when
connected with an SSL connection, log in to MySQL as root and then issue
the following command:
GRANT SELECT, INSERT, UPDATE, DELETE ON prod_database.* TO 'database_user'@'%' REQUIRE SSL;
Note: If the user already exists, you must revoke all existing
privileges for the user and then use the preceding
GRANT statement to
give the appropriate privileges to the user.
Remember to run a
FLUSH PRIVILEGES for the database to make the
privilege change take effect.
