Validating AWS Lambda Code Using AWS Signer

AWS Lambda code signing is the practice of digitally signing source code packages for functions and layers. The goal of code signing is to ensure that only trusted code runs in your AWS Lambda functions.

AWS Signer is a fully-managed code-signing service that can be used to verify the integrity of your AWS Lambda code. Before your code is deployed, AWS Lambda will perform a series of validation checks which will determine whether to accept or reject the deployment package.

In this lab, you will work in the AWS console to configure code signing for an AWS Lambda function using AWS Signer. This lab also covers the signature validation process in detail, including the validation checks and policies that can be applied to your code signing configurations.
