Control: 41 RDS for SQL Server DB instances should be encrypted in transit

Description

This control checks whether a connection to an Amazon RDS for Microsoft SQL Server DB instance is encrypted in transit. The control fails if the rds.force_ssl parameter of the parameter group associated with the DB instance is set to 0 (off).

Data in transit refers to data that moves from one location to another, such as between nodes in a DB cluster or between a DB cluster and a client application. Data can move across the internet or within a private network. Encrypting data in transit reduces the risk of unauthorized users eavesdropping on network traffic.

Remediation

For information about enabling SSL/TLS for connections to Amazon RDS DB instances running Microsoft SQL Server, see Using SSL with a Microsoft SQL Server DB Instance in the Amazon Relational Database Service User Guide.

Usage

Run the control in your terminal:

powerpipe control run aws_compliance.control.foundational_security_rds_41

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run aws_compliance.control.foundational_security_rds_41 --share

SQL

This control uses a named query:
