Description

API Gateway will accept HTTP methods without authorization so anyone could potentially access resources behind the gateway.

How to fix?

Set authorization attribute to value other than NONE.

Example Configuration

resource "aws_api_gateway_method" "any" {
  rest_api_id   = aws_api_gateway_rest_api.this.id
  resource_id   = aws_api_gateway_resource.this.id
  http_method   = "ANY"
  authorization = "AWS_IAM"
