AWS CloudFront origin protocol policy does not enforce HTTPS-only misconfiguration detected in code

Rule Details

Cortex AppSec Rule ID	APPSEC2_AWS_72
Category - Subcategory	Public Exposure - Encryption And Protocols
Provider	AWS
Severity	MEDIUM
Framework	CloudFormation, Terraform, Terraform Plan

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 ...
