MySQL server databases do not have Enforce SSL connection enabled

Description

SSL connectivity provides a new layer of security by connecting a database server to client applications using Secure Sockets Layer (SSL). Enforcing SSL connections between a database server and client applications helps protect against man-in-the-middle attacks. This is achieved by encrypting the data stream between the server and application.

We recommend you set Enforce SSL connection to Enable on MYSQL Server databases.
