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

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 'man in the middle' attacks by encrypting the data stream between the server and application.

Azure Database for PostgreSQL

Azure Database for PostgreSQL is a relational database service based on the open-source Postgres database engine. It's a fully managed database as a service offering that can handle mission-critical workloads with predictable performance, security, high availability, and dynamic scalability. It's available in two deployment options, Single Server and Hyperscale (Citus) (preview). The Hyperscale (Citus) option horizontally scales queries across multiple machines using sharding, and serves applications that require greater scale and performance
