AWS AppSync API caches should be encrypted at rest¶

This control checks whether an AWS AppSync API cache is encrypted at rest. The control fails if the API cache isn't encrypted at rest.

How to fix¶

Attribute at_rest_encryption_enabled of aws_appsync_api_cache 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_appsync_api_cache.

resource "aws_appsync_graphql_api" "this" {
  name                = "pofix-example-api"
  authentication_type = "API_KEY"
}

resource "aws_appsync_api_cache" "this" {
  api_caching_behavior = "FULL_REQUEST_CACHING"
  api_id               = "abc123"
  ttl                  = 3600
  type                 = "SMALL"

  at_rest_encryption_enabled = 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.
