Cognito identity pools should not allow unauthenticated identities¶

This control checks whether an Amazon Cognito identity pool is configured to allow unauthenticated identities. The control fails if guest access is activated (the AllowUnauthenticatedIdentities parameter is set to true) for the identity pool.

How to fix¶

Attribute allow_unauthenticated_identities of aws_cognito_identity_pool must be false.

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_cognito_identity_pool.

resource "aws_cognito_identity_pool" "this" {
  identity_pool_name = "pofix-example-pool"

  allow_unauthenticated_identities = false
}

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.
