CloudFormation stacks should have notifications enabled¶

Ensure CloudFormation stacks are associated with an SNS topic to receive notifications when an event occurs.

How to fix¶

Attribute notification_arns of aws_cloudformation_stack must be non-empty.

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_cloudformation_stack.

resource "aws_cloudformation_stack" "this" {
  disable_rollback  = false
  name              = "pofix-example-stack"
  notification_arns = ["arn:aws:sns:us-east-1:123456789012:cloudformation-notifications"]
  template_body     = jsonencode({ AWSTemplateFormatVersion = "2010-09-09", Description = "Empty stack", Resources = { NullResource = { Type = "AWS::CloudFormation::WaitConditionHandle" } } })
}

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.
