Transition to IMDSv2 on EC2 - Introduction, Preparation, Pitfalls

IMDSv2 can improve EC2 security. For a couple of weeks, AWS Foundational Security Best Practices recommends that EC2 instances use IMDSv2 (control EC2.8).

This video explains why IMDSv2 is useful and what attacks it protects you against, including a live demo. I also highlight a pitfall with Docker containers in a demo. Last but not least, I show you the preparation steps for a smooth transition.
