# Encrypting client connections with SSL/TLS to MySQL DB instances on Amazon RDS
<a name="mysql-ssl-connections"></a>

Secure Sockets Layer (SSL) is an industry-standard protocol for securing network connections between client and server. After SSL version 3.0, the name was changed to Transport Layer Security (TLS). Amazon RDS supports SSL/TLS encryption for MySQL DB instances. Using SSL/TLS, you can encrypt a connection between your application client and your MySQL DB instance. SSL/TLS support is available in all AWS Regions for MySQL.

With Amazon RDS, you can secure data in transit by encrypting client connections to MySQL DB instances with SSL/TLS, requiring SSL/TLS for all connections to a MySQL DB instance, and connecting from the MySQL command-line client with SSL/TLS (encrypted). The following sections provide guidance on configuring and utilizing SSL/TLS encryption for MySQL DB instances on Amazon RDS.
