Using Aws Waf With User

In this solution, we will use Pulumi to create and manage AWS WAF (Web Application Firewall) resources using TypeScript. AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. We will create a WAF WebACL and associate it with an Application Load Balancer (ALB). The key services involved in this solution are AWS WAF, AWS ALB, and Pulumi.

Introduction

In this solution, we will use Pulumi to create and manage AWS WAF (Web Application Firewall) resources using TypeScript. AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. We will create a WAF WebACL and associate it with an Application Load Balancer (ALB). The key services involved in this solution are AWS WAF, AWS ALB, and Pulumi.

Step-by-Step Explanation

Step 1: Set up Pulumi and AWS Credentials

First, ensure that you have Pulumi installed and configured with your AWS credentials. You can follow the Pulumi documentation to set up your environment.

Step 2: Create a New Pulumi Project

Create a new Pulumi project using TypeScript. You can do this by running pulumi new aws-typescript in your terminal and following the prompts.

Step 3: Install Required Pulumi Packages

Install the necessary Pulumi packages for AWS by running npm install @pulumi/aws.

Step 4: Define the WAF WebACL

In your Pulumi program, define a new WAF WebACL. This will include specifying the rules and conditions for the WebACL.

Step 5: Create an Application Load Balancer (ALB)

Define and create an ALB in your Pulumi program. This will be the resource that you will associate with the WAF WebACL.

Step 6: Associate the WAF WebACL with the ALB

Associate the WAF WebACL with the ALB by specifying the ALB ARN in the WebACL association.

Step 7: Deploy the Pulumi Stack

Deploy your Pulumi stack by running pulumi up in your terminal. This will create the WAF WebACL and associate it with the ALB.

Key Points

• AWS WAF helps protect web applications from common web exploits.
• Pulumi allows you to define and manage cloud resources using code.
• The key services involved in this solution are AWS WAF, AWS ALB, and Pulumi.
• Ensure that you have Pulumi installed and configured with your AWS credentials.
• Define the WAF WebACL and ALB in your Pulumi program.
• Associate the WAF WebACL with the ALB.
• Deploy the Pulumi stack to create and manage the resources.

Conclusion

In this solution, we demonstrated how to use Pulumi to create and manage AWS WAF resources using TypeScript. By following the step-by-step instructions, you can set up a WAF WebACL and associate it with an ALB to protect your web applications from common web exploits. Pulumi makes it easy to define and manage cloud resources using code, providing a powerful and flexible way to manage your infrastructure.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create a WAF WebACL
const webAcl = new aws.waf.WebAcl("webAcl", {
    defaultAction: { type: "ALLOW" },
    metricName: "webAclMetric",
    rules: [{
        action: { type: "BLOCK" },
        priority: 1,
        ruleId: "example-rule-id",
        type: "REGULAR",
    }],
});

// Create an Application Load Balancer (ALB)
const alb = new aws.alb.LoadBalancer("alb", {
    internal: false,
    loadBalancerType: "application",
    securityGroups: ["sg-12345678"],
    subnets: ["subnet-12345678", "subnet-87654321"],
});

// Associate the WAF WebACL with the ALB
const webAclAssociation = new aws.wafv2.WebAclAssociation("webAclAssociation", {
    resourceArn: alb.arn,
    webAclArn: webAcl.arn,
});

export const webAclArn = webAcl.arn;
export const loadBalancerArn = alb.arn;
export const webAclAssociationId = webAclAssociation.id;
