Code signing in AWS is the practice of digitally signing source code packages for AWS Lambda functions and AWS IoT devices. The goal of code signing is to ensure that only trusted code runs in these compute resources.

AWS Signer is a fully-managed code-signing service that can be used to verify the integrity of your AWS Lambda code.

This hands-on lab challenge will test your practical ability to modify a solution in a production-like AWS environment. You will be presented with a task and set of requirements you must fulfill to pass the challenge.

This is a real environment, which means you can prove your knowledge in an applied way, substituting multiple choice questions for a dynamic performance-based exam situation.
