IMDSv1 to IMDSv2 Migration Lab

This lab will guide you through identifying and migrating EC2 instances from the less secure IMDSv1 to the more secure IMDSv2 using Terraform automation and security best practices.

Overview

The EC2 Instance Metadata Service (IMDS) provides access to instance metadata from within EC2 instances. IMDSv2 introduces important security improvements over IMDSv1, including session-oriented requests and additional protection against certain types of attacks.

What You’ll Learn

• Understanding the security differences between IMDSv1 and IMDSv2
• Identifying instances currently using IMDSv1
• Using Terraform to enforce IMDSv2 requirements
• Monitoring and compliance strategies

Prerequisites

Before starting this lab, ensure you have:

• An active AWS account
• Terraform installed and configured
• Basic understanding of EC2 and AWS CLI
• Understanding of infrastructure as code concepts
