Questions and Answers
The best place to start is Chapter 1, Security.
Other portions of the MySQL Documentation which you may find useful with regard to specific security concerns include the following:
Most 5.1 binaries have support for SSL connections between the client and server. See Section 5.6, “Using SSL for Secure Connections”.
You can also tunnel a connection using SSH, if (for example) the client application does not support SSL connections. For an example, see Section 5.8, “Connecting to MySQL Remotely from Windows with SSH”.
Most 5.1 binaries have SSL enabled for client-server connections that are secured, authenticated, or both. See Section 5.6, “Using SSL for Secure Connections”.
As of MySQL 5.6.4, the Enterprise edition includes a PAM Authentication Plugin that supports authentication against an LDAP directory.
