Overview
This AWS Solutions Construct implements an AWS WAF web ACL connected to an Application Load Balancer.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { WafwebaclToAlbProps, WafwebaclToAlb } from "@aws-solutions-constructs/aws-wafwebacl-alb";

// Use an existing ALB, such as one created by Route53toAlb or AlbToLambda
const existingLoadBalancer = previouslyCreatedLoadBalancer


// Note - all alb constructs turn on ELB logging by default, so require that an environment including account
// and region be provided when creating the stack
//
// new MyStack(app, 'id', {env: {account: '123456789012', region: 'us-east-1' }});
//
// This construct can only be attached to a configured Application Load Balancer.
new WafwebaclToAlb(this, 'test-wafwebacl-alb', {
existingLoadBalancerObj: existingLoadBalancer
});

Python
from aws_solutions_constructs.aws_route53_alb import Route53ToAlb
from aws_solutions_constructs.aws_wafwebacl_alb import WafwebaclToAlbProps, WafwebaclToAlb
from aws_cdk import (
aws_route53 as route53,
Stack
)
from constructs import Construct

# Use an existing ALB, such as one created by Route53toAlb or AlbToLambda
existingLoadBalancer = previouslyCreatedLoadBalancer

# Note - all alb constructs turn on ELB logging by default, so require that an environment including account
# and region be provided when creating the stack
#
# MyStack(app, 'id', env=cdk.Environment(account='123456789012', region='us-east-1'))
#
# This construct can only be attached to a configured Application Load Balancer.
WafwebaclToAlb(self, 'test_wafwebacl_alb',
existing_load_balancer_obj=existingLoadBalancer
)

Pattern Construct Props



Name
Type
Description




existingLoadBalancerObj
elbv2.ApplicationLoadBalancer
The existing Application Load Balancer Object that will be protected with the WAF web ACL. Note that a WAF web ACL can only be added to a configured Application Load Balancer, so this construct only accepts an existing ApplicationLoadBalancer and does not accept applicationLoadBalancerProps.


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.


loadBalancer
elbv2.ApplicationLoadBalancer
Returns an instance of the Application Load Balancer Object created by the pattern.



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
