Enterprise Key Management in inSync

 Enterprise Key Management is under controlled availability.  To enable this feature for your account, contact Druva Support.

Overview

If your organizational policies require you to have full control over the encryption of the data backed up by Druva inSync from your cloud applications and devices, Enterprise Key Management is the option for you.  With Enterprise Key Management, you can use keys generated from your own AWS Key Management Service (KMS) account to encrypt and decrypt the data backed up by Druva inSync. This provides an additional layer of encryption over and above Druva's default data encryption.

Enterprise Key Management is available on request, hence contact Druva Support to acquire this feature for your account.

Benefits

Enterprise Key Management offers the following security benefits:

  • Use keys from your own KMS account to encrypt and decrypt the data encryption key.
  • Generate, revoke, rotate, and destroy the encryption keys as and when required from AWS account.
  • Control access to data backed up by Druva inSync.
  • Secure data backed up from Endpoints and Cloud apps.

Considerations

Consider the following points before you enable this feature for your account:

  • Once enabled, you cannot revoke Enterprise Key Management for your account.
  • Enterprise Key Management encryption supersedes Cloud Key Management. Hence, Cloud Key Management gets disabled when Enterprise Key Management is enabled for your account.

Prerequisites

Ensure the following before you enable Enterprise Key Management:

  • AWS  account with Key Management Service (KMS) access, to manage customer master keys
  • Druva Support has activated the Enterprise Key Management configuration for your account. Without this activation, the configuration fields do not appear on the inSync Management Console.

  1. Copy the Druva's  AWS account ID from the inSync Management Console:
    1. Login to the inSync Management Console.

    4. Click Create key and click Symmetric key on the Key type page. 
    5. On the Add labels page, provide the key Alias, used to identify the key and description and click Next.
    6. On the Key administrators' page, select one or more administrators who can control the key. The key administrator selected here can rotate, and revoke the key that you are about to generate.
    7. Select Allow key administrators to delete this key to enable the delete right for the administrators.
    8. On the next page, click Add another AWS account. A text box is displayed. This setting defines the account with which the AWS KMS must communicate to authenticate access to the backed up data.

    1. Click Enable Enterprise Key Management. inSync asks for the KMS key ARN generated from the AWS KMS console.
    2. Copy the newly created KMS key ARN into the Update KMS key ARN dialog box and click Next. The ARN is validated and upon successful authentication, a confirmation message appears.
    3. Click Save.

Update the Enterprise Encryption key

You may have to update the Enterprise Encryption key to comply with your organizational security policies. However, it is important to note that you must keep the old and new encryption keys active in your AWS KMS service until you configure the new KMS key ARN on the inSync Management Console. This ensures all the required permissions are transferred from the old key to the new encryption key before the old key is purged by the AWS KMS.

To update the Enterprise Encryption key:

  1. Get the new KMS key ARN using the steps provided above.
  2. On the Key Management tab,  click Update KMS Key ARN.
  3. Copy the newly created KMS key ARN into the Update KMS key ARN dialog box and click Save. The KMS Key ARN upon successful validation is updated on the inSync Management Console.
