Prerequisites​

This guide assumes that you have already installed and configured Fix Inventory to collect your AWS resources.

Directions​

  1. Execute the following search command in Fix Inventory Shell:

    > search is(aws_rds_instance) and volume_encrypted==false
    ​kind=aws_rds_instance, ..., region=fixinventory-poweruser
    ​kind=aws_rds_instance, ..., account=poweruser-team

  2. Pipe the search command into the dump command:

    > search is(aws_rds_instance) and volume_encrypted==false | dump
    ​reported:
    ​  id: /aws/rds/123
    ​  name: some-name
    ​  ctime: '2022-12-05T22:53:14Z'
    ​  kind: aws_rds_instance
    ​  age: 2mo28d

    The command output will list the details of all non-compliant aws_rds_instance resources.
