## Impact

This rule identifies CloudFront web distributions which have a default SSL certificate to access CloudFront content. It is a best practice to use custom SSL Certificate to access CloudFront content. It gives you full control over the content data. custom SSL certificates also allow your users to access your content by using an alternate domain name. You can use a certificate stored in AWS Certificate Manager (ACM) or you can use a certificate stored in IAM.

## How to Fix

## \[source,go]

resource "aws\_cloudfront\_distribution" "pass\_1" {

origin { domain\_name = aws\_s3\_bucket.primary.bucket\_regional\_domain\_name origin\_id = "primaryS3"

s3\_origin\_config { origin\_access\_identity = aws\_cloudfront\_origin\_access\_identity.default.cloudfront\_access\_identity\_path } }

default\_cache\_behavior { target\_origin\_id = "groupS3" }

## viewer\_certificate { acm\_certificate\_arn = "aaaaa" } }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/public-exposure/appsec2-aws-42.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
