Description:

This policy ensures that all backups of data stored in Amazon S3 are encrypted. This helps to protect the data from unauthorized access in the event of a data breach or other incident.

Rationale:

Encryption is a critical component of any data protection strategy. By encrypting backups, organizations can help to protect their data from unauthorized access, even if the backups are compromised.

Impact:

The impact of this policy is that all backups of data stored in Amazon S3 will be encrypted. This will help to protect the data from unauthorized access and make it more difficult for attackers to gain access to sensitive information.

Default Value:

AWS will recommend that you encrypt all backups of data stored in Amazon S3. This is the default setting for Amazon S3 backups.

Pre-requisites:

To implement this policy, you will need to have the following:

  • Access to the AWS Management Console or the AWS CLI
  • The AWS Key Management Service (KMS)
  • A KMS key that will be used to encrypt the backups

Remediation Steps:

If you are not already encrypting your backups, you can follow these steps to remediate the issue:

  1. Create a KMS key in the AWS KMS console.
  2. Associate the KMS key with the S3 bucket that contains the backups.
  3. Enable encryption for the S3 bucket.

Test Plan:

To test that the policy is working correctly, you can follow these steps:

  1. Upload a file to the S3 bucket.
  2. Verify that the file is encrypted by using the AWS KMS console or the AWS CLI.

Implementation Plan:

To implement this policy, you can follow these steps:

  1. Create a KMS key in the AWS KMS console.
  2. Associate the KMS key with the S3 bucket that contains the backups.
  3. Enable encryption for the S3 bucket.

AWS CLI Process:

To encrypt your backups using the AWS CLI, you can use the following command:

aws s3 cp s3://bucket/file s3://bucket/file --sse aws:kms

Using AWS GUI:

To encrypt your backups using the AWS Management Console, you can follow these steps:

  1. Go to the Amazon S3 console.
  2. Click the name of the bucket that contains the backups.
  3. Click the Properties tab.
  4. Under Encryption, select the Enable encryption checkbox.
  5. Select the KMS key that you want to use to encrypt the backups.
  6. Click Save.

Backout Plan:

To revoke the policy, you can follow these steps:

  1. Disable encryption for the S3 bucket.
  2. Delete the KMS key that was used to encrypt the backups.

Note:

This policy is not intended to replace other data protection measures, such as access control and auditing.
