25 Apr 2023 08:00:29 Administrators can enable SMB encryption for the entire server, or just specific shares. All Managed Disks, Snapshots, and Images are encrypted using Storage Service Encryption using a service-managed key. Server-side encryption with Microsoft-managed keys does imply the service has full access to store and manage the keys. This new feature provides complete control over data security, making it easier than ever to meet compliance and regulatory requirements. Azure Key Vault can handle requesting and renewing Transport Layer Security (TLS) certificates. Operations that are included involve: Taking manual COPY-ONLY backup of a database encrypted by service-managed TDE is not supported in Azure SQL Managed Instance, since the certificate used for encryption is not accessible. 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. Best practice: Use a secure management workstation to protect sensitive accounts, tasks, and data. By encrypting data, you help protect against tampering and eavesdropping attacks. 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. You can configure a site-to-site VPN connection to a virtual network by using the Azure portal, PowerShell, or Azure CLI. Whenever Azure Customer traffic moves between datacenters-- outside physical boundaries not controlled by Microsoft (or on behalf of Microsoft)-- a data-link layer encryption method using the IEEE 802.1AE MAC Security Standards (also known as MACsec) is applied from point-to-point across the underlying network hardware. Azure Storage Service Encryption (SSE) can automatically encrypt data before it is stored, and it automatically decrypts the data when you retrieve it. Keys are not available to Azure services, Microsoft manages key rotation, backup, and redundancy. It covers the major areas of encryption, including encryption at rest, encryption in flight, and key management with Azure Key Vault. 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. Double encryption of data at rest mitigates threats with two, separate layers of encryption to protect against compromises of any single layer. Data encryption with customer-managed keys for Azure Cosmos DB for PostgreSQL enables you to bring your own key to protect data at rest. It is recommended that whenever possible, IaaS applications leverage Azure Disk Encryption and Encryption at Rest options provided by any consumed Azure services. It performs real-time encryption and decryption of the database, associated backups, and transaction log files at rest without requiring changes to the application. The pages in an encrypted database are encrypted before they are written to disk and are decrypted when theyre read into memory. When available a customer typically opens the Azure portal for the target subscription and resource provider and checks a box indicating, they would like the data to be encrypted. This policy grants the service identity access to receive the key. 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. The following table compares key management options for Azure Storage encryption. Infrastructure as a Service (IaaS) customers can have a variety of services and applications in use. The Secure Socket Tunneling Protocol (SSTP) is used to create the VPN tunnel. Sets the transparent data encryption protector for a server. This MACsec encryption is on by default for all Azure traffic traveling within a region or between regions, and no action is required on customers part to enable. It performs real-time encryption and decryption of the database, associated backups, and transaction log files at rest without requiring changes to the application. This paper focuses on: Encryption at Rest is a common security requirement. Permissions to access keys can be assigned to services or to users through Azure Active Directory accounts. This article summarizes and provides resources to help you use the Azure encryption options. 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. ), monitoring usage, and ensuring only authorized parties can access them. Data Lake Store supports "on by default," transparent encryption of data at rest, which is set up during the creation of your account. To learn more about BYOK for Azure SQL Database and Azure Synapse, see Transparent data encryption with Azure Key Vault integration. As a result, this model is not appropriate for most organizations unless they have specific key management requirements. Applies to: Best practice: Move larger data sets over a dedicated high-speed WAN link. Encryption is the secure encoding of data used to protect confidentiality of data. Most endpoint attacks take advantage of the fact that users are administrators in their local workstations. Each section includes links to more detailed information. When sending encrypted traffic between an Azure virtual network and an on-premises location over the public internet, use Azure VPN Gateway. The following table shows which client libraries support which versions of client-side encryption and provides guidelines for migrating to client-side encryption v2. Then, only authorized users can access this data, with any restrictions that you specify. Protection of customer data stored within Azure Services is of paramount importance to Microsoft. Apply labels that reflect your business requirements. Once an Azure SQL Database customer enables TDE key are automatically created and managed for them. (used to grant access to Key Vault). With proper file protection, you can analyze data flows to gain insight into your business, detect risky behaviors and take corrective measures, track access to documents, and so on. Additionally, custom solutions should use Azure managed service identities to enable service accounts to access encryption keys. The service can perform Azure Active Directory authentication and receive an authentication token identifying itself as that service acting on behalf of the subscription. Use the following set of commands for Azure SQL Database and Azure Synapse: Learn more about related concepts in the following articles: More info about Internet Explorer and Microsoft Edge, generated by the key vault or transferred to the key vault, Transparent data encryption with Azure Key Vault integration, Turn on transparent data encryption by using your own key from Key Vault, Migrate Azure PowerShell from AzureRM to Az, Set-AzSqlDatabaseTransparentDataEncryption, Get-AzSqlDatabaseTransparentDataEncryption, Set-AzSqlServerTransparentDataEncryptionProtector, Get-AzSqlServerTransparentDataEncryptionProtector, sys.dm_pdw_nodes_database_encryption_keys, Create Or Update Transparent Data Encryption Configuration, Get Transparent Data Encryption Configuration, List Transparent Data Encryption Configuration Results, Extensible key management by using Azure Key Vault (SQL Server), Transparent data encryption with Bring Your Own Key support. By using SSH keys for authentication, you eliminate the need for passwords to sign in. To restore an existing TDE-encrypted database, the required TDE certificate must first be imported into the SQL Managed Instance. Storing an encryption key in Azure Key Vault ensures secure key access and central management of keys. Below you have examples of how they fit on each model: Software as a Service (SaaS) customers typically have encryption at rest enabled or available in each service. Microsoft also provides encryption to protect Azure SQL Database, Azure Cosmos DB, and Azure Data Lake. Likewise, if the BACPAC file is imported to a SQL Server instance, the new database also isn't automatically encrypted. The change in default will happen gradually by region. 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. Optionally, you can choose to add a second layer of encryption with keys you manage using the customer-managed keys or CMK feature. All new and existing block blobs, append blobs, and page blobs are encrypted, including blobs in the archive tier. 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. Double encryption of Azure Storage data protects against a scenario where one of the encryption algorithms or keys may be compromised. You can use a site-to-site VPN gateway connection to connect your on-premises network to an Azure virtual network over an IPsec/IKE (IKEv1 or IKEv2) VPN tunnel. No customer control over the encryption keys (key specification, lifecycle, revocation, etc. Existing SQL Managed Instance databases created before February 2019 are not encrypted by default. This includes where and how encryption keys are created, and stored as well as the access models and the key rotation procedures. To achieve that goal secure key creation, storage, access control, and management of the encryption keys must be provided. Any customer using Azure Infrastructure as a Service (IaaS) features can achieve encryption at rest for their IaaS VMs and disks through Azure Disk Encryption. Use access controls to revoke access to individual users or services in Azure Key Vault or Managed HSM. Opinions and technologies change over time and this article is updated on a regular basis to reflect those changes. This exported content is stored in unencrypted BACPAC files. This protection technology uses encryption, identity, and authorization policies. For information about encryption and key management for Azure managed disks, see Server-side encryption of Azure managed disks. The scope in this case would be a subscription, a resource group, or just a specific key vault. Data at rest Microsoft's approach to enabling two layers of encryption for data at rest is: Encryption at rest using customer-managed keys. Azure Key Vault supports customer creation of keys or import of customer keys for use in customer-managed encryption key scenarios. Service-level encryption supports the use of either Microsoft-managed keys or customer-managed keys with Azure Key Vault. Storage Service Encryption uses 256-bit Advanced Encryption Standard (AES) encryption, which is one of the strongest block ciphers available. Attacks against data at-rest include attempts to obtain physical access to the hardware on which the data is stored, and then compromise the contained data. This library also supports integration with Key Vault for storage account key management. Enable platform encryption services. No setup is required. Gets the TDE configuration for a database. TDE encrypts the storage of an entire database by using a symmetric key called the Database Encryption Key (DEK). Azure Data Factory also provides advanced security features, such as data encryption at rest and in transit, and integrates with Azure Active Directory to manage user access and permissions. TDE is enabled on the new database, but the BACPAC file itself still isn't encrypted. For more information, see data encryption models. It provides features for a robust solution for certificate lifecycle management. 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. This approach is called cell-level encryption or column-level encryption (CLE), because you can use it to encrypt specific columns or even specific cells of data with different encryption keys. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az. You provide your own key for data encryption at rest. 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. When you interact with Azure Storage through the Azure portal, all transactions take place over HTTPS. You maintain complete control of the keys. With client-side encryption, you can manage and store keys on-premises or in another secure location. If the predefined roles don't fit your needs, you can define your own roles. Azure SQL Database currently supports encryption at rest for Microsoft-managed service side and client-side encryption scenarios. Microsoft is committed to encryption at rest options across cloud services and giving customers control of encryption keys and logs of key use. For documentation on Transparent Data Encryption for dedicated SQL pools inside Synapse workspaces, see Azure Synapse Analytics encryption. For more information about encryption scopes, see Encryption scopes for Blob storage. 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). Gets a specific Key Vault key from a server. Conversely, if you want a user to be able to read vault properties and tags but not have any access to keys, secrets, or certificates, you can grant this user read access by using Azure RBAC, and no access to the data plane is required. It is recommended not to store any sensitive data in system databases. Azure Storage encryption is enabled for all storage accounts, including both Resource Manager and classic storage accounts. Encryption at rest may also be required by an organization's need for data governance and compliance efforts. Restore of backup file to Azure SQL Managed Instance, SQL Server running on an Azure virtual machine also can use an asymmetric key from Key Vault. For these cmdlets, see AzureRM.Sql. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The exception is tempdb, which is always encrypted with TDE to protect the data stored there. As described previously, the goal of encryption at rest is that data that is persisted on disk is encrypted with a secret encryption key. All Azure Storage redundancy options support encryption, and all data in both the primary and secondary regions is encrypted when geo-replication is enabled. The Azure services that support each encryption model: * This service doesn't persist data. Encryption at rest keys are made accessible to a service through an access control policy. Azure provides double encryption for data at rest and data in transit. Typically, the foundational Azure resource providers will store the Data Encryption Keys in a store that is close to the data and quickly available and accessible while the Key Encryption Keys are stored in a secure internal store. Data encryption at rest is a mandatory step toward data privacy, compliance, and data sovereignty. ** This service supports storing data in your own Key Vault, Storage Account, or other data persisting service that already supports Server-Side Encryption with Customer-Managed Key. Some items considered customer content, such as table names, object names, and index names, may be transmitted in log files for support and troubleshooting by Microsoft. Key Vault is the Microsoft-recommended solution for managing and controlling access to encryption keys used by cloud services. In either case, when leveraging this encryption model, the Azure Resource Provider receives an encrypted blob of data without the ability to decrypt the data in any way or have access to the encryption keys. By using the Azure Backup service, you can back up and restore encrypted virtual machines (VMs) that use Key Encryption Key (KEK) configuration. Use point-in-time-restore feature to move this type of database to another SQL Managed Instance, or switch to customer-managed key. For example, Azure Storage may receive data in plain text operations and will perform the encryption and decryption internally. For Azure SQL Managed Instance, the TDE protector is set at the instance level and it is inherited by all encrypted databases on that instance. 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. For many customers, the essential requirement is to ensure that the data is encrypted whenever it is at rest. Detail: All transactions occur via HTTPS. All Azure hosted services are committed to providing Encryption at Rest options. Update your code to use client-side encryption v2. Azure Storage uses service-side encryption (SSE) to automatically encrypt your data when it is persisted to the cloud. Performance and availability guarantees are impacted, and configuration is more complex. For more information, see Azure Storage Service Encryption for Data at Rest. Customers can verify SQL Database and SQL Managed Instance compliance with internal security policies in independent third-party audit reports available on the Microsoft Trust Center. In transit: When data is being transferred between components, locations, or programs, it's in transit. To learn more about encryption of data in transit in Data Lake, see Encryption of data in Data Lake Store. If you are currently using v1, we recommend that you update your application to use client-side encryption v2 and migrate your data. Client encryption model Gets the transparent data encryption state for a database. It includes: With client-side encryption, cloud service providers dont have access to the encryption keys and cannot decrypt this data. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To help protect data in the cloud, you need to account for the possible states in which your data can occur, and what controls are available for that state. Detail: Use site-to-site VPN. 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. Create a site-to-site connection in the Azure portal, Create a site-to-site connection in PowerShell, Create a virtual network with a site-to-site VPN connection by using CLI. In addition to its data integration capabilities, Azure Data Factory also provides . Azure Disk Encryption helps protect and safeguard your data to meet your organizational security and compliance commitments. Enables or disables transparent data encryption for a database. More info about Internet Explorer and Microsoft Edge, Azure Synapse Analytics (dedicated SQL pool (formerly SQL DW) only), Azure Resource Providers perform the encryption and decryption operations, Customer controls keys via Azure Key Vault, Customer controls keys on customer-controlled hardware, Customers manage and store keys on-premises (or in other secure stores). The labels include visual markings such as a header, footer, or watermark. Different models of key storage are supported. When server-side encryption using customer-managed keys in customer-controlled hardware is used, the key encryption keys are maintained on a system configured by the customer. All Azure AD servers are configured to use TLS 1.2. Key Vault streamlines the key management process and enables you to maintain control of keys that access and encrypt your data. All Azure Storage resources are encrypted, including blobs, disks, files, queues, and tables. TDE protects data and log files, using AES and Triple Data Encryption Standard (3DES) encryption algorithms. For Azure SQL Managed Instance, TDE is enabled at the instance level and newly created databases. You can also use Storage REST API over HTTPS to interact with Azure Storage. In addition to encrypting data prior to storing it in persistent media, the data is also always secured in transit by using HTTPS. The Resource Provider might use encryption keys that are managed by Microsoft or by the customer depending on the provided configuration. It performs real-time encryption and decryption of the database, associated backups, and transaction log files at rest without requiring changes to the application. You can configure Azure VPN gateways to use a custom IPsec/IKE policy with specific cryptographic algorithms and key strengths, rather than the Azure default policy sets. All object metadata is also encrypted. For more information on Azure Disk encryption, see Azure Disk Encryption for Linux VMs or Azure Disk Encryption for Windows VMs. Because data is moving back and forth from many locations, we generally recommend that you always use SSL/TLS protocols to exchange data across different locations. For example, to grant access to a user to manage key vaults, you would assign the predefined role Key Vault Contributor to this user at a specific scope. Best practices for Azure data security and encryption relate to the following data states: Protecting your keys is essential to protecting your data in the cloud. Keys must be stored in a secure location with identity-based access control and audit policies. This article describes best practices for data security and encryption. Client Encryption model refers to encryption that is performed outside of the Resource Provider or Azure by the service or calling application. Azure VPN gateways use a set of default proposals. For more information about the cryptographic modules underlying Azure Storage encryption, see Cryptography API: Next Generation. In this course, you will learn how to apply additional encryption protection for data at rest on Azure resources, including Azure storage, Azure Disk Encryption, Recovery Vaults, Transparent Data Encryption, and Always Encrypted databases. Best practice: Store certificates in your key vault. Azure Key Vault is designed to support application keys and secrets. However, configuration is complex, and most Azure services dont support this model. 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. Permissions to use the keys stored in Azure Key Vault, either to manage or to access them for Encryption at Rest encryption and decryption, can be given to Azure Active Directory accounts. Additionally, Microsoft is working towards encrypting all customer data at rest by default. It can traverse firewalls (the tunnel appears as an HTTPS connection). You can find the related Azure policy here. Some Azure services enable the Host Your Own Key (HYOK) key management model. You can use the Azure Storage Client Library for .NET NuGet package to encrypt data within your client applications prior to uploading it to your Azure storage. To see the encryption at rest options available to you, examine the Data encryption models: supporting services table for the storage and application platforms that you use.
