EventBridge S3 Auto-Remediation
Build an automated compliance guardrail that detects non-compliant S3 bucket ACLs, policies, and encryption changes via CloudTrail and EventBridge, then auto-remediates with a Node.js Lambda backed by CloudWatch alarms and SNS notifications.
Lab Overview
Security misconfigurations on S3 buckets are among the most common causes of data breaches. A DevOps Engineer Professional must be able to build automated guardrails that detect and revert non-compliant changes in near real-time.
In this lab you will:
- Create a CloudTrail trail that captures S3 bucket-level management API events (PutBucketAcl, PutBucketPolicy, DeleteBucketEncryption)
- Build a Node.js Lambda function that inspects CloudTrail events, identifies non-compliant configurations, and reverts them (resetting public ACLs, removing overly permissive bucket policies, re-enabling encryption)
- Wire up an EventBridge rule to route S3 CloudTrail events to the remediation Lambda
- Simulate a non-compliant PutBucketAcl and observe the automatic remediation
- Publish a custom CloudWatch metric from the Lambda and create a CloudWatch alarm that notifies an SNS topic
Every resource is tagged for easy identification and cleanup. All operations use the AWS CLI in us-east-1.
What You'll Learn
Create a CloudTrail trail that captures S3 bucket-level management API events for use in EventBridge rules
Build a Node.js Lambda function that parses CloudTrail events and remediates non-compliant S3 bucket configurations
Configure an EventBridge rule to match S3 CloudTrail events and route them to a Lambda target
Test auto-remediation by simulating a public bucket ACL and verifying the Lambda reverts it
Publish a custom CloudWatch metric from the remediation Lambda for operational visibility
Create a CloudWatch alarm on the custom remediation metric and integrate with an SNS topic
