RDS DB instances should have deletion protection enabled

Ensure AWS Relational Database Service (AWS RDS) instances have deletion protection enabled.

How to fix

Attribute deletion_protection of aws_db_instance must be true.

Implementation options

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

Use the compliance.tf registry module to get this control enforced by default. This control is mapped to the frameworks shown in the tabs above. To begin, see get started with compliance.tf.

}

Option 2: Open source module (terraform-aws-modules)

If you use terraform-aws-modules/rds/aws, configure the required module inputs to satisfy this control. You can later migrate to the compliance.tf module with minimal changes because it is compatible by design.

module "rds" {
  source  = "terraform-aws-modules/rds/aws"
  version = ">=7.0.0"

  allocated_storage      = 20
  db_name                = "myapp"
  db_subnet_group_name   = "example-db-subnet-group"
  engine                 = "postgres"
  engine_version         = "16.1"
  identifier             = "abc123"
  instance_class         = "db.t3.micro"
  password               = "change-me-in-production"
  username               = "dbadmin"
  vpc_security_group_ids = ["sg-12345678"]

  deletion_protection = true
}

Option 3: 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_db_instance.

resource "aws_db_instance" "this" {
  allocated_storage               = 20
  enabled_cloudwatch_logs_exports = ["general", "slowquery"]
  engine                          = "mysql"
  identifier                      = "pofix-example-db"
  instance_class                  = "db.t3.micro"
  monitoring_interval             = 60
  monitoring_role_arn             = "arn:aws:iam::123456789012:role/example-role"
  password                        = "ChangeMe123!"
  skip_final_snapshot             = true
  username                        = "dbadmin"

  deletion_protection = 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.
