Network Firewall firewalls should have deletion protection enabled¶

This control checks whether an AWS Network Firewall firewall has deletion protection enabled. The control fails if deletion protection isn't enabled for a firewall.

How to fix¶

Attribute delete_protection of aws_networkfirewall_firewall 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_networkfirewall_firewall.

resource "aws_networkfirewall_firewall" "this" {
  firewall_policy_arn = "arn:aws:network-firewall:us-east-1:123456789012:firewall-policy/example"
  name                = "pofix-example-firewall"

  subnet_mapping {
    subnet_id = "subnet-12345678"
  }

  vpc_id = "vpc-12345678"

  delete_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.
