About this Hands-on Lab

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Single-Region Symmetrical KMS Key

You will want to create a new symmetrical KMS key with the name of cloud_user.
During the creation process, you will also update the KMS key policy to allow:

  • the S3 bucket to use the key
  • the cloud_user IAM user access as a key administrator
Set Up Amazon S3 Default Encryption via KMS

After your KMS key and policy are created, you will want to assign the KMS key as the default method for encryption at rest within the Amazon S3 bucket.

Schedule AWS KMS Key Deletion

After testing and verifying the upload works, you can now schedule the KMS key to be deleted in seven days.
