Apparently they are going to implement TLS. Searching I found What is TLS/SSL?
> SQL access
> With Microsoft SQL Server, you can require authentication of the client when connecting to the server running SQL Server. Either the client or server can be configured to require encryption of the data that is transferred between them. Very sensitive information, such as financial or medical databases, can be protected to prevent unauthorized access and disclosure of information about the network.
What I would like to find is instructions on what is needed to implement to SQL Server.
