APPLIES TO: Azure Database for PostgreSQL - Single Server

Important

Azure Database for PostgreSQL - Single Server is on the retirement path. We strongly recommend that you upgrade to Azure Database for PostgreSQL - Flexible Server. For more information about migrating to Azure Database for PostgreSQL - Flexible Server, see What's happening to Azure Database for PostgreSQL Single Server?.

This article helps you validate that data encryption using customer managed key for Azure Database for PostgreSQL is working as expected.

Check the encryption status

From portal

  1. If you want to verify that the customer's key is used for encryption, follow these steps:

    • In the Azure portal, navigate to the Azure Key Vault -> Keys

    • Select the key used for server encryption.

    • Set the status of the key Enabled to No.

      After some time (~15 min), the Azure Database for PostgreSQL server Status should be Inaccessible. Any I/O operation done against the server will fail which validates that the server is indeed encrypted with customers key and the key is currently not valid.

      In order to make the server Available against, you can revalidate the key.

    • Set the status of the key in the Key Vault to Yes.

    • On the server Data Encryption, select Revalidate key.

    • After the revalidation of the key is successful, the server Status changes to Available

  2. On the Azure portal, if you can ensure that the encryption key is set, then data is encrypted using the customers key used in the Azure portal. Under Security, select Data encryption.

From CLI

  1. We can use az CLI command to validate the key resources being used for the Azure Database for PostgreSQL server.

    az postgres server key list --name  '<server_name>'  -g '<resource_group_name>'

    For a server without Data encryption set, this command will results in empty set [].

Azure audit reports

Audit Reports can also be reviewed that provides information about the compliance with data protection standards and regulatory requirements.
