How do I enable server-side encryption for AWS S3 buckets for data protection?

In this guide, you’ll learn how to enable server-side encryption for AWS S3 buckets to protect your data. We will create an S3 bucket and configure it to use server-side encryption with the default (AES-256) algorithm. We’ll use AWS’s aws_s3_bucket, aws_s3_bucket_server_side_encryption_configuration, and aws_s3_bucket_versioning resources to accomplish this.

Explanation

1. aws_s3_bucket: This defines a new S3 bucket.
2. aws_s3_bucket_server_side_encryption_configuration: This sets the server-side encryption configuration with AES-256 encryption for the S3 bucket.
3. aws_s3_bucket_versioning: (Optional) This enables versioning for the S3 bucket to provide additional protection and data management features.

Program

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

// Create S3 bucket
const example = new aws.s3.BucketV2("example", {
    bucket: "example-bucket-server-side-encryption",
    acl: "private",
    tags: {
        Name: "example-bucket-server-side-encryption",
        Environment: "Dev",
    },
});
// Enable server-side encryption on the bucket
const exampleBucketServerSideEncryptionConfigurationV2 = new aws.s3.BucketServerSideEncryptionConfigurationV2("example", {
    bucket: example.bucket,
    rules: [{
        applyServerSideEncryptionByDefault: {
            sseAlgorithm: "AES256",
        },
    }],
});
// Optional: Enable versioning on the bucket
const exampleBucketVersioningV2 = new aws.s3.BucketVersioningV2("example", {
    bucket: example.bucket,
    versioningConfiguration: {
        status: "Enabled",
    },
});
export const bucketId = example.id;
export const bucketArn = example.arn;
export const bucketRegion = example.region;

Key Points

• Security: Server-side encryption with AES-256 ensures data is encrypted at rest.
• Resource Configuration: Specific AWS resources such as aws_s3_bucket, aws_s3_bucket_server_side_encryption_configuration, and optional versioning via aws_s3_bucket_versioning.
• Flexibility: Option to enable versioning for better data management and protection.

Summary

We’ve demonstrated how to create an AWS S3 bucket with server-side encryption enabled. This setup ensures that all objects stored in the bucket are encrypted using the AES-256 algorithm, providing enhanced security for your data. Additionally, versioning can be enabled for better data management practices.
