Enforce SSL/TLS for all incoming connections on CloudSQL Database Instances

Like any network aware service, SQL database connections also need to be protected on the wire. If the database connection is unencrypted then it may be possible to perform a man in the middle attack that may allow an attacker to retrieve and tamper SQL queries and data. The risk is highest for databases that allow Internet located IP addresses to connect for access. A successful attack can lead to data compromise.
