## Impact

This rule detects whether the AWS CloudFront distribution is configured to use HTTPS as the only allowed protocol for communication between CloudFront and its origin. Enforcing HTTPS-only ensures that data transmitted over the network is encrypted. Using HTTPS helps protect sensitive information, maintain data integrity, and secure communication channels. If this configuration is not enforced, data could be sent using unencrypted HTTP, which is vulnerable to interception and eavesdropping by malicious actors.

## How to Fix

*Resource:* AWS::CloudFront::Distribution

* *Arguments:* DistributionConfig.Origins.CustomOriginConfig.OriginProtocolPolicy

## In this example, the origin protocol policy in your AWS CloudFront distribution enforces HTTPS-only communication by configuring the `OriginProtocolPolicy` attribute to `https-only`. \[source,go]

ExamplePassHttpsOnlyDistribution: Type: "AWS::CloudFront::Distribution" Properties: DistributionConfig: Enabled: true Origins:

* DomainName: "example.data.mediastore.amazonaws.com" # contains important domain name Id: "custom-origin-example" CustomOriginConfig: OriginProtocolPolicy: "https-only" # HTTPS only ...

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/public-exposure/appsec2-aws-72.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
