Using Aws Dynamodb With Cloudtrails

Introduction

In this guide, we will demonstrate how to set up AWS DynamoDB with AWS CloudTrail using Pulumi. DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. By integrating DynamoDB with CloudTrail, you can monitor and log all actions taken on your DynamoDB tables.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, ensure you have Pulumi installed and configured. Then, create a new Pulumi project:

pulumi new aws-typescript

Step 2: Install Dependencies

Install the necessary Pulumi packages for AWS:

npm install @pulumi/aws

Step 3: Create DynamoDB Table

In your index.ts file, add the following code to create a DynamoDB table:

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

const table = new aws.dynamodb.Table("my-table", {
    attributes: [
        { name: "id", type: "S" },
    ],
    hashKey: "id",
    billingMode: "PAY_PER_REQUEST",
});

Step 4: Enable CloudTrail

Add the following code to enable CloudTrail and log DynamoDB actions:

const trail = new aws.cloudtrail.Trail("my-trail", {
    s3BucketName: "my-cloudtrail-bucket",
    includeGlobalServiceEvents: true,
    isMultiRegionTrail: true,
    enableLogFileValidation: true,
    eventSelectors: [{
        readWriteType: "All",
        includeManagementEvents: true,
        dataResources: [{
            type: "AWS::DynamoDB::Table",
            values: [table.arn],
        }],
    }],
});

Step 5: Export Outputs

Export the names of the created resources:

export const tableName = table.name;
export const trailName = trail.name;

Summary

In this guide, we created a DynamoDB table and enabled CloudTrail to log all actions on the table. This setup helps in monitoring and auditing the operations on your DynamoDB tables, ensuring better compliance and security. For more details, refer to the Pulumi AWS DynamoDB documentation and AWS CloudTrail documentation.

Full Code Example

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

// Create a DynamoDB table
const table = new aws.dynamodb.Table("my-table", {
    attributes: [
        { name: "id", type: "S" },
    ],
    hashKey: "id",
    billingMode: "PAY_PER_REQUEST",
});

// Enable CloudTrail and log DynamoDB actions
const trail = new aws.cloudtrail.Trail("my-trail", {
    s3BucketName: "my-cloudtrail-bucket",
    includeGlobalServiceEvents: true,
    isMultiRegionTrail: true,
    enableLogFileValidation: true,
    eventSelectors: [{
        readWriteType: "All",
        includeManagementEvents: true,
        dataResources: [{
            type: "AWS::DynamoDB::Table",
            values: [table.arn],
        }],
    }],
});

// Export the names of the created resources
export const tableName = table.name;
export const trailName = trail.name;
