## Overview
This AWS Solutions Construct implements an AWS WAF web ACL connected to Amazon API Gateway REST API.
Here is a minimal deployable pattern definition:
Typescript
```python
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import * as lambda from "aws-cdk-lib/aws-lambda";
import { ApiGatewayToLambda } from '@aws-solutions-constructs/aws-apigateway-lambda';
import { WafwebaclToApiGatewayProps, WafwebaclToApiGateway } from "@aws-solutions-constructs/aws-wafwebacl-apigateway";
const apiGatewayToLambda = new ApiGatewayToLambda(this, 'ApiGatewayToLambdaPattern', {
lambdaFunctionProps: {
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler',
code: lambda.Code.fromAsset(`lambda`)
}
});
// This construct can only be attached to a configured API Gateway.
new WafwebaclToApiGateway(this, 'test-wafwebacl-apigateway', {
existingApiGatewayInterface: apiGatewayToLambda.apiGateway
});
```
Python
```python
from aws_solutions_constructs.aws_apigateway_lambda import ApiGatewayToLambda
from aws_solutions_constructs.aws_wafwebacl_apigateway import WafwebaclToApiGatewayProps, WafwebaclToApiGateway
from aws_cdk import (
aws_apigateway as api,
aws_lambda as _lambda,
Stack
)
from constructs import Construct
api_gateway_to_lambda = ApiGatewayToLambda(self, 'ApiGatewayToLambdaPattern',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset(
'lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
)
)
# This construct can only be attached to a configured API Gateway.
WafwebaclToApiGateway(self, 'test_wafwebacl_apigateway',
existing_api_gateway_interface=api_gateway_to_lambda.api_gateway
)
```
Java
```java
import software.constructs.Construct;
import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.services.apigateway.*;
import software.amazon.awscdk.services.lambda.*;
import software.amazon.awscdk.services.lambda.Runtime;
import software.amazon.awsconstructs.services.apigatewaylambda.*;
import software.amazon.awsconstructs.services.wafwebaclapigateway.*;
final ApiGatewayToLambda apiGatewayToLambda = new ApiGatewayToLambda(this, "ApiGatewayToLambdaPattern",
new ApiGatewayToLambdaProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_16_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.build());
// This construct can only be attached to a configured Application Load
// Balancer.
new WafwebaclToApiGateway(this, "test-wafwebacl-apigateway", new WafwebaclToApiGatewayProps.Builder()
.existingApiGatewayInterface(apiGatewayToLambda.getApiGateway())
.build());
```
## Pattern Construct Props
| **Name** | **Type** | **Description** |
|:-------------|:----------------|-----------------|
|existingApiGatewayInterface|[`api.IRestApi`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_apigateway.IRestApi.html)|The existing API Gateway instance that will be protected with the WAF web ACL. *Note that a WAF web ACL can only be added to a configured API Gateway, so this construct only accepts an existing IRestApi and does not accept apiGatewayProps.*|
|existingWebaclObj?|[`waf.CfnWebACL`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_waf.CfnWebACL.html)|Existing instance of a WAF web ACL, an error will occur if this and props is set.|
|webaclProps?|[`waf.CfnWebACLProps`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_waf.CfnWebACLProps.html)|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)`](../core/lib/waf-defaults.ts) function from core to create an array entry from each desired managed rule set.|
## Pattern Properties
| **Name** | **Type** | **Description** |
|:-------------|:----------------|-----------------|
|webacl|[`waf.CfnWebACL`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_waf.CfnWebACL.html)|Returns an instance of the waf.CfnWebACL created by the construct.|
|apiGateway|[`api.IRestApi`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_apigateway.IRestApi.html)|Returns an instance of the API Gateway REST API 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](https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-groups-list.html).
* 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 API Gateway
* User provided API Gateway object is used as-is
