    This AWS Solutions Construct implements an AWS WAF web ACL connected to Amazon CloudFront.

    Here is a minimal deployable pattern definition:


    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


    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',


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

    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.

    Pattern Properties

    Name Type 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:


    • 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

    • Send metrics to Amazon CloudWatch

    Amazon CloudFront

    • User provided CloudFront object is used as-is
