AWS DocumentDB clusters should be encrypted at rest

This control checks whether an AWS DocumentDB cluster is encrypted at rest. The control fails if an AWS DocumentDB cluster isn't encrypted at rest.

How to fix

Attribute storage_encrypted of aws_docdb_cluster must be true.

Implementation options

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Terraform AWS provider resources

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_docdb_cluster.

resource "aws_docdb_cluster" "this" {
  backup_retention_period         = 7
  cluster_identifier              = "pofix-example-docdb"
  enabled_cloudwatch_logs_exports = ["audit", "profiler"]
  master_password                 = "ChangeMe123!"
  master_username                 = "dbadmin"

  storage_encrypted = true
}
Which option should I choose?
  • Compliance.tf module (recommended): controls enforced by default and mapped to frameworks.
  • Open source module (terraform-aws-modules): compatible by design with compliance.tf. Same variable names for an easy, low-change migration path when you are ready.
  • Terraform AWS provider resources: manage Terraform resources directly.
