Cloudfront integrated waf remediation

Using Console

Using CLI

To remediate the misconfiguration of CloudFront not being integrated with AWS WAF for AWS using AWS CLI, follow the steps below:

Open the AWS CLI on your local machine.
Run the following command to create a new Web ACL in AWS WAF:

aws wafv2 create-web-acl --name <name-of-web-acl> --scope CLOUDFRONT --default-action block --description "<description-of-web-acl>"

Replace <name-of-web-acl> and <description-of-web-acl> with the desired name and description for your Web ACL.

Run the following command to get the ARN of the newly created Web ACL:

aws wafv2 list-web-acls --scope CLOUDFRONT --query "WebACLs[?Name=='<name-of-web-acl>'].ARN" --output text

Replace <name-of-web-acl> with the name of the Web ACL you created in step 2.

Run the following command to update the CloudFront distribution to use the new Web ACL:

aws cloudfront update-distribution --id <distribution-id> --web-acl-id <web-acl-arn> --web-acl-override

Replace <distribution-id> with the ID of the CloudFront distribution you want to update, and <web-acl-arn> with the ARN of the Web ACL you retrieved in step 3.

Wait for the CloudFront distribution to update and propagate the changes.

After completing these steps, your CloudFront distribution will be integrated with AWS WAF, and the new Web ACL will be applied to all incoming traffic.

Using Python

To remediate the misconfiguration of CloudFront not being integrated with AWS WAF, you can follow these steps using Python:

Import the necessary modules:

import boto3

Create a boto3 client for AWS WAF:

waf_client = boto3.client('waf')

Create a boto3 client for CloudFront:

cf_client = boto3.client('cloudfront')

Get the distribution ID of the CloudFront distribution that needs to be integrated with AWS WAF:

distribution_id = 'YOUR_DISTRIBUTION_ID'

Get the current configuration of the CloudFront distribution:

response = cf_client.get_distribution_config(Id=distribution_id)

Check if the distribution already has an AWS WAF web ACL ID configured:

if 'WebACLId' in response['DistributionConfig']['WebACLId']:
    print('The CloudFront distribution is already integrated with AWS WAF.')
else:
    print('The CloudFront distribution is not integrated with AWS WAF.')

If the distribution is not integrated with AWS WAF, get the ID of the AWS WAF web ACL that needs to be associated with the distribution:

web_acl_id = 'YOUR_WEB_ACL_ID'

Update the configuration of the CloudFront distribution to integrate it with AWS WAF:

response['DistributionConfig']['WebACLId'] = web_acl_id
cf_client.update_distribution(DistributionConfig=response['DistributionConfig'], Id=distribution_id, IfMatch=response['ETag'])

Verify that the CloudFront distribution is now integrated with AWS WAF:

response = cf_client.get_distribution_config(Id=distribution_id)
if 'WebACLId' in response['DistributionConfig']['WebACLId']:
    print('The CloudFront distribution is now integrated with AWS WAF.')
else:
    print('Failed to integrate CloudFront distribution with AWS WAF.')

You can save this code as a Python script and execute it using a Python interpreter to remediate the misconfiguration of CloudFront not being integrated with AWS WAF.
