Control: 4.3.1 Ensure 'Enforce SSL connection' is set to 'ENABLED' for PostgreSQL Database Server

Description

It is recommended to enable SSL connection on PostgreSQL Servers. SSL connectivity helps to provide a new layer of security, by connecting database server to client applications using Secure Sockets Layer (SSL). Enforcing SSL connections between database server and client applications helps protect against attacks by encrypting the data stream between the server and application.

For each database, go to Settings section from left pane.
Click on Connection security and go to SSL settings.
For Enforce SSL connection, click on ENABLED.
