Overview
This AWS Solutions Construct implements an AWS WAF web ACL connected to Amazon CloudFront.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { CloudFrontToS3 } from '@aws-solutions-constructs/aws-cloudfront-s3';
import { WafwebaclToCloudFront } from "@aws-solutions-constructs/aws-wafwebacl-cloudfront";

const cloudfrontToS3 = new CloudFrontToS3(this, 'test-cloudfront-s3', {});

// This construct can only be attached to a configured CloudFront.
new WafwebaclToCloudFront(this, 'test-wafwebacl-cloudfront', {
existingCloudFrontWebDistribution: cloudfrontToS3.cloudFrontWebDistribution
});

Python
from aws_solutions_constructs.aws_cloudfront_s3 import CloudFrontToS3
from aws_solutions_constructs.aws_wafwebacl_cloudfront import WafwebaclToCloudFront
from aws_cdk import Stack
from constructs import Construct

cloudfront_to_s3 = CloudFrontToS3(self, 'test_cloudfront_s3')

# This construct can only be attached to a configured CloudFront.
WafwebaclToCloudFront(self, 'test_wafwebacl_cloudfront',
existing_cloud_front_web_distribution=cloudfront_to_s3.cloud_front_web_distribution
)

Java
import software.constructs.Construct;

import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awsconstructs.services.cloudfronts3.*;
import software.amazon.awsconstructs.services.wafwebaclcloudfront.*;

final CloudFrontToS3 cloudfrontToS3 = new CloudFrontToS3(this, "test-cloudfront-s3",
new CloudFrontToS3Props.Builder()
.build());

// This construct can only be attached to a configured CloudFront.
new WafwebaclToCloudFront(this, "test-wafwebacl-cloudfront", new WafwebaclToCloudFrontProps.Builder()
.existingCloudFrontWebDistribution(cloudfrontToS3.getCloudFrontWebDistribution())
.build());

Pattern Construct Props

Name
Type
Description

existingCloudFrontWebDistribution
cloudfront.Distribution
The existing CloudFront instance that will be protected with the WAF web ACL. Note that a WAF web ACL can only be added to a configured CloudFront, so this construct only accepts an existing Distribution and does not accept cloudfrontProps.

existingWebaclObj?
waf.CfnWebACL
Existing instance of a WAF web ACL, an error will occur if this and props is set.

webaclProps?
waf.CfnWebACLProps
Optional user-provided props to override the default props for the AWS WAF web ACL. To use a different collection of managed rule sets, specify a new rules property. Use our wrapManagedRuleSet(managedGroupName: string, vendorName: string, priority: number) function from core to create an array entry from each desired managed rule set.

Description

webacl
waf.CfnWebACL
Returns an instance of the waf.CfnWebACL created by the construct.

cloudFrontWebDistribution
cloudfront.Distribution
Returns an instance of cloudfront.Distribution created by the construct.

Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
AWS WAF

Deploy a WAF web ACL with 7 AWS managed rule groups.

AWSManagedRulesBotControlRuleSet
AWSManagedRulesKnownBadInputsRuleSet
AWSManagedRulesCommonRuleSet
AWSManagedRulesAnonymousIpList
AWSManagedRulesAmazonIpReputationList
AWSManagedRulesAdminProtectionRuleSet
AWSManagedRulesSQLiRuleSet

Note that the default rules can be replaced by specifying the rules property of CfnWebACLProps
