Description

Although FSx for Windows file systems are encrypted by default with AWS-managed keys, customer-managed keys provide full control over access and administration policies and key rotation which may help meet compliance and security requirements.

How to fix?

Set the kms_key_id attribute in aws_fsx_windows_file_system resource to a valid key_arn.

Example Configuration

resource "aws_fsx_windows_file_system" "allow1" {
  active_directory_id = aws_directory_service_directory.rule-730.id
  subnet_ids          = [data.aws_subnet.subnet-1.id]
  throughput_capacity = 1024
  kms_key_id          = data.aws_kms_key.custom_key.arn
  storage_capacity    = 1200
}
