Description:

This policy ensures that backup media is encrypted. This is important to protect data from unauthorized access.

Rationale:

Backup media is a valuable asset that contains sensitive data. If backup media is not encrypted, it could be accessed by unauthorized individuals. This could lead to data breaches, which could have a significant impact on the organization.

Impact:

The impact of not encrypting backup media could be significant. If backup media is not encrypted, it could be accessed by unauthorized individuals. This could lead to data breaches, which could have a significant impact on the organization. For example, the organization could lose customers, suffer financial losses, or be subject to regulatory fines.

Default Value:

AWS recommends that organizations encrypt all backup media. This can be done using a variety of methods, such as:

  • Using AWS Key Management Service (KMS) to encrypt the backup media
  • Using a third-party encryption solution

Pre-requisites:

To implement this policy, you will need to have access to the encryption tools. You will also need to have the appropriate permissions to encrypt the backup media.

Remediation Steps:

The following steps can be used to remediate this policy:

  1. Identify the encryption tools that will be used.
  2. Configure the encryption tools.
  3. Test the encryption tools.
  4. Document the encryption process.

Test Plan:

The following steps can be used to test the encryption process:

  1. Verify that the encryption tools are configured correctly.
  2. Verify that the encryption tools are able to encrypt the backup media.

Implementation Plan:

The following steps can be used to implement the encryption process:

  1. Identify the encryption tools that will be used.
  2. Configure the encryption tools.
  3. Test the encryption tools.
  4. Document the encryption process.

AWS CLI Process:

The following command can be used to encrypt backup media using the AWS CLI:

aws kms encrypt --key-id my-key-id --plaintext file://my-backup-file

Using AWS GUI:

The following steps can be used to encrypt backup media using the AWS Management Console:

  1. Go to the AWS Management Console.
  2. Click on the "KMS" service.
  3. Click on the "Keys" tab.
  4. Select the key that you want to use to encrypt the backup media.
  5. Click on the "Encrypt" button.
  6. Select the backup file that you want to encrypt.
  7. Click on the "Encrypt" button.

Backout Plan:

The following steps can be used to revoke the changes made to implement this policy:

  1. Delete the encryption keys.

Note:

  • This policy is not intended to replace the need for a comprehensive disaster recovery plan.
  • This policy is specific to AWS resources. Other resources, such as on-premises servers, may require different encryption procedures.
