Loss of key encryption keys means loss of data. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az. Key Vault provides central key management, leverages tightly monitored HSMs, and enables separation of duties between management of keys and data to help meet compliance with security policies. Storage Service Encryption uses 256-bit Advanced Encryption Standard (AES) encryption, which is one of the strongest block ciphers available. Organizations have the option of letting Azure completely manage Encryption at Rest. Infrastructure-level encryption relies on Microsoft-managed keys and always uses a separate key. There are two versions of client-side encryption available in the client libraries: Using client-side encryption v1 is no longer recommended due to a security vulnerability in the client library's implementation of CBC mode. This protection technology uses encryption, identity, and authorization policies. For more information, see Client-side encryption for blobs and queues. 25 Apr 2023 08:00:29 To start using TDE with Azure Key Vault integration, see the how-to guide Turn on transparent data encryption by using your own key from Key Vault. For example, if you want to grant an application access to use keys in a key vault, you only need to grant data plane access permissions by using key vault access policies, and no management plane access is needed for this application. Infrastructure services, or Infrastructure as a Service (IaaS) in which customer deploys operating systems and applications that are hosted in the cloud and possibly leveraging other cloud services. Encryption keys and secrets are safeguarded in your Azure Key Vault subscription. Best practice: Ensure endpoint protection. Azure Disk Encryption helps protect and safeguard your data to meet your organizational security and compliance commitments. Key vaults also control and log the access to anything stored in them. Data may be partitioned, and different keys may be used for each partition. The following resources are available to provide more general information about Azure security and related Microsoft services: More info about Internet Explorer and Microsoft Edge, Deploy Certificates to VMs from customer-managed Key Vault, Azure resource providers encryption model support to learn more, Azure security best practices and patterns. For Azure SQL Database and Azure Synapse, you can manage TDE for the database in the Azure portal after you've signed in with the Azure Administrator or Contributor account. In that model, the Resource Provider performs the encrypt and decrypt operations. AKS docs ( link) says Kubernetes secrets are stored in etcd, a distributed key-value store. As of June 2017, Transparent Data Encryption (TDE) is enabled by default on newly created databases. Enable platform encryption services. Data at transit: This includes data that is being transferred between components, locations, or programs. If an attacker obtains a hard drive with encrypted data but not the encryption keys, the attacker must defeat the encryption to read the data. It covers the major areas of encryption, including encryption at rest, encryption in flight, and key management with Azure Key Vault. In addition to satisfying compliance and regulatory requirements, encryption at rest provides defense-in-depth protection. You can encrypt files that will be at rest either before storing them or by encrypting the entirety of a given storage drive or device. The built-in server certificate is unique for each server and the encryption algorithm used is AES 256. The Blob Storage and Queue Storage client libraries uses AES in order to encrypt user data. Azure Data Lake is an enterprise-wide repository of every type of data collected in a single place prior to any formal definition of requirements or schema. Data encrypted by an application thats running in the customers datacenter or by a service application. A symmetric encryption key is used to encrypt data as it is written to storage. To configure TDE through the Azure portal, you must be connected as the Azure Owner, Contributor, or SQL Security Manager. Ability to encrypt multiple services to one master, Can segregate key management from overall management model for the service, Can define service and key location across regions, Customer has full responsibility for key access management, Customer has full responsibility for key lifecycle management, Additional Setup & configuration overhead, Full control over the root key used encryption keys are managed by a customer provided store, Full responsibility for key storage, security, performance, and availability, Full responsibility for key access management, Full responsibility for key lifecycle management, Significant setup, configuration, and ongoing maintenance costs. Keys should be backed up whenever created or rotated. This policy grants the service identity access to receive the key. Gets the encryption result for a database. Soft-Delete and purge protection must be enabled on any vault storing key encryption keys to protect against accidental or malicious cryptographic erasure. Gets the transparent data encryption protector, SET ENCRYPTION ON/OFF encrypts or decrypts a database, Returns information about the encryption state of a database and its associated database encryption keys, Returns information about the encryption state of each Azure Synapse node and its associated database encryption keys, Adds an Azure Active Directory identity to a server. In Azure, the default setting for TDE is that the DEK is protected by a built-in server certificate. Best practice: Control what users have access to. More than one encryption key is used in an encryption at rest implementation. by Ned Bellavance. All Azure Storage services (Blob storage, Queue storage, Table storage, and Azure Files) support server-side encryption at rest; some services additionally support customer-managed keys and client-side encryption. For Azure SQL Managed Instance use Transact-SQL (T-SQL) to turn TDE on and off on a database. In addition to encrypting data prior to storing it in persistent media, the data is also always secured in transit by using HTTPS. More info about Internet Explorer and Microsoft Edge, Client-side encryption for blobs and queues, Server-side encryption of Azure managed disks, Use customer-managed keys for Azure Storage encryption, Provide an encryption key on a request to Blob Storage, Create an account that supports customer-managed keys for queues, Create an account that supports customer-managed keys for tables, Create a storage account with infrastructure encryption enabled for double encryption of data, Azure Storage updating client-side encryption in SDK to address security vulnerability, SDK support matrix for client-side encryption, Customer-managed keys for Azure Storage encryption, Blob Storage client libraries for .NET (version 12.13.0 and above), Java (version 12.18.0 and above), and Python (version 12.13.0 and above). Microsoft-managed keys are rotated appropriately per compliance requirements. To learn more about client-side encryption with Key Vault and get started with how-to instructions, see Tutorial: Encrypt and decrypt blobs in Azure Storage by using Key Vault. Azure Database for MySQL, Security, BYOK, Double Encryption SMB 3.0, which used to access Azure Files shares, supports encryption, and it's available in Windows Server 2012 R2, Windows 8, Windows 8.1, and Windows 10. When you export a TDE-protected database, the exported content of the database isn't encrypted. Detail: All transactions occur via HTTPS. Azure Information Protection is a cloud-based solution that helps an organization to classify, label, and protect its documents and emails. If you choose to use ExpressRoute, you can also encrypt the data at the application level by using SSL/TLS or other protocols for added protection. A TDE certificate is automatically generated for the server that contains the database. Encryption at Rest is a common security requirement. The exception is tempdb, which is always encrypted with TDE to protect the data stored there. Data encryption at rest is available for services across the software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) cloud models. TDE performs real-time I/O encryption and decryption of the data at the page level. The TDE settings on the source database or primary database are transparently inherited on the target. Transparent data encryption - Azure SQL Database & SQL Managed Instance In the wrong hands, your application's security or the security of your data can be compromised. If you are managing your own keys, you can rotate the MEK. You can manage it locally or store it in Key Vault. It performs real-time encryption and decryption of the database, associated backups, and transaction log files at rest without requiring changes to the application. DEK is protected by the TDE protector. For Azure SQL Database and Azure Synapse, the TDE protector is set at the server level and is inherited by all databases associated with that server. With TDE with Azure Key Vault integration, users can control key management tasks including key rotations, key vault permissions, key backups, and enable auditing/reporting on all TDE protectors using Azure Key Vault functionality. The Azure services that support each encryption model: * This service doesn't persist data. To ensure this data is encrypted at rest, IaaS applications can use Azure Disk Encryption on an Azure IaaS virtual machine (Windows or Linux) and virtual disk. The process is completely transparent to users. For operations using encryption keys, a service identity can be granted access to any of the following operations: decrypt, encrypt, unwrapKey, wrapKey, verify, sign, get, list, update, create, import, delete, backup, and restore. Best practice: Use a secure management workstation to protect sensitive accounts, tasks, and data. However, configuration is complex, and most Azure services dont support this model. You maintain complete control of the keys. It is recommended not to store any sensitive data in system databases. SSH is an encrypted connection protocol that allows secure sign-ins over unsecured connections. Detail: Azure Resource Manager can securely deploy certificates stored in Azure Key Vault to Azure VMs when the VMs are deployed. The Queue Storage client libraries for .NET and Python also support client-side encryption. See Deploy Certificates to VMs from customer-managed Key Vault for more information. While processing the data on a virtual machine, data can be persisted to the Windows page file or Linux swap file, a crash dump, or to an application log. The three server-side encryption models offer different key management characteristics, which you can choose according to your requirements: Service-managed keys: Provides a combination of control and convenience with low overhead. Encryption of data at rest is one of the most important options available here which can be leveraged to encrypt Azure Virtual Machine data, storage account data, and various other at-rest data sources such as databases in Azure. To learn more about encryption of data in transit in Data Lake, see Encryption of data in Data Lake Store. Customers can store the master key in a Windows certificate store, Azure Key Vault, or a local Hardware Security Module. Administrators can enable SMB encryption for the entire server, or just specific shares. Azure services support either service-managed keys, customer-managed keys, or client-side encryption. Best practice: Apply disk encryption to help safeguard your data. To use TDE with BYOK support and protect your databases with a key from Key Vault, open the TDE settings under your server. As a result, this model is not appropriate for most organizations unless they have specific key management requirements. Later the attacker would put the hard drive into a computer under their control to attempt to access the data. Detail: Access to a key vault is controlled through two separate interfaces: management plane and data plane. All Azure AD servers are configured to use TLS 1.2. 2 For information about creating an account that supports using customer-managed keys with Table storage, see Create an account that supports customer-managed keys for tables. Use the following cmdlets for Azure SQL Database and Azure Synapse: For Azure SQL Managed Instance, use the T-SQL ALTER DATABASE command to turn TDE on and off on a database level, and check sample PowerShell script to manage TDE on an instance level. Encryption keys are managed by Microsoft and are rotated per Microsoft internal guidelines. Encryption at rest is a mandatory measure required for compliance with some of those regulations. However, the Azure Storage client libraries for Blob Storage and Queue Storage also provide client-side encryption for customers who need to encrypt data on the client. This library also supports integration with Key Vault for storage account key management. Organizations that don't enforce data encryption are more exposed to data-confidentiality issues. Azure Storage uses service-side encryption (SSE) to automatically encrypt your data when it is persisted to the cloud. Update your code to use client-side encryption v2. This feature enables developers to encrypt data inside client applications before putting in into Azure Storage. Data in a new storage account is encrypted with Microsoft-managed keys by default. For Azure SQL Managed Instance, TDE is enabled at the instance level and newly created databases. The server-side encryption model with customer-managed keys in Azure Key Vault involves the service accessing the keys to encrypt and decrypt as needed. See, Queue Storage client library for .NET (version 12.11.0 and above) and Python (version 12.4 and above), Queue Storage client library for .NET (version 12.10.0 and below) and Python (version 12.3.0 and below), Update your application to use a version of the Queue Storage SDK version that supports client-side encryption v2. Consider using the service-side encryption features provided by Azure Storage to protect your data, instead of client-side encryption. There are multiple Azure encryption models. In some Resource Managers server-side encryption with service-managed keys is on by default. Public Preview : Azure Cosmos DB for PostgreSQL Data Encryption with One of two keys in Double Key Encryption follows this model. Amazon S3. A more complete Encryption at Rest solution ensures that the data is never persisted in unencrypted form. All object metadata is also encrypted. Infrastructure as a Service (IaaS) customers can have a variety of services and applications in use. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Detail: Use ExpressRoute. For many customers, the essential requirement is to ensure that the data is encrypted whenever it is at rest. Configuring Encryption for Data at Rest in Microsoft Azure. It can traverse firewalls (the tunnel appears as an HTTPS connection). We recommend that you tightly control who has contributor access to your key vaults, to ensure that only authorized persons can access and manage your key vaults, keys, secrets, and certificates. Transparent data encryption (TDE) helps protect Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics against the threat of malicious offline activity by encrypting data at rest. In these cases, you can enable the Encryption at Rest support as provided by each consumed Azure service. TDE protects data and log files, using AES and Triple Data Encryption Standard (3DES) encryption algorithms. For more information about how to create a storage account that enables infrastructure encryption, see Create a storage account with infrastructure encryption enabled for double encryption of data. Security Control: Enable encryption at rest - Microsoft Community Hub To restore an existing TDE-encrypted database, the required TDE certificate must first be imported into the SQL Managed Instance. Additionally, custom solutions should use Azure managed service identities to enable service accounts to access encryption keys. Keys are stored and managed in key vaults, and access to a key vault can be given to users or services. Azure Synapse Analytics. Key Vault relieves organizations of the need to configure, patch, and maintain hardware security modules (HSMs) and key management software. Doing so gives you more granular encryption capability than TDE, which encrypts data in pages. For more detail on Key Vault authorization see the secure your key vault page in the Azure Key Vault documentation. With client-side encryption, you can manage and store keys on-premises or in another secure location. Connections also use RSA-based 2,048-bit encryption key lengths. Find the TDE settings under your user database. Because the vast majority of attacks target the end user, the endpoint becomes one of the primary points of attack. With Azure SQL Database, you can apply symmetric encryption to a column of data by using Transact-SQL. Data encryption at rest is a mandatory step toward data privacy, compliance, and data sovereignty. Blob Storage client library for .NET (version 12.12.0 and below), Java (version 12.17.0 and below), and Python (version 12.12.0 and below), Update your application to use a version of the Blob Storage SDK that supports client-side encryption v2. Examples are transfer over the network, across a service bus (from on-premises to cloud and vice-versa, including hybrid connections such as ExpressRoute), or during an input/output process. Three types of keys are used in encrypting and decrypting data: the Master Encryption Key (MEK), Data Encryption Key (DEK), and Block Encryption Key (BEK). By default, Azure Kubernetes Service (AKS) provides encryption at rest for all disks using Microsoft-managed keys. Encryption is the secure encoding of data used to protect confidentiality of data. Using client-side encryption with Table Storage is not recommended. Data encryption at rest is a mandatory step toward data privacy, compliance, and data sovereignty. When using client-side encryption, customers encrypt the data and upload the data as an encrypted blob. Newly created Azure SQL databases will be encrypted at rest by default Use access controls to revoke access to individual users or services in Azure Key Vault or Managed HSM. No customer control over the encryption keys (key specification, lifecycle, revocation, etc. Additionally, since the service does have access to the DEK during the encryption and decryption operations the overall security guarantees of this model are similar to when the keys are customer-managed in Azure Key Vault. Reviews pros and cons of the different key management protection approaches. TDE is used to encrypt SQL Server, Azure SQL Database, and Azure Synapse Analytics data files in real time, using a Database Encryption Key (DEK), which is stored in the database boot record for availability during recovery. Data that is already encrypted when it is received by Azure. If a user has contributor permissions (Azure RBAC) to a key vault management plane, they can grant themselves access to the data plane by setting a key vault access policy. The encrypted data is then uploaded to Azure Storage. Therefore, encryption in transport should be addressed by the transport protocol and should not be a major factor in determining which encryption at rest model to use. In this scenario, the TDE Protector that encrypts the DEK is a customer-managed asymmetric key, which is stored in a customer-owned and managed Azure Key Vault (Azure's cloud-based external key management system) and never leaves the key vault. Azure Storage encryption for data at rest Azure Storage uses service-side encryption (SSE) to automatically encrypt your data when it is persisted to the cloud. Server-side Encryption models refer to encryption that is performed by the Azure service. This ensures that your data is secure and protected at all times. While some customers may want to manage the keys because they feel they gain greater security, the cost and risk associated with a custom key storage solution should be considered when evaluating this model. Amazon S3 supports both client and server encryption of data at Rest. The master database contains objects that are needed to perform TDE operations on user databases. The MEK is used to encrypt the DEK, which is stored on persistent media, and the BEK is derived from the DEK and the data block.
