Description Use customer-managed keys to manage the encryption at rest of your Azure Cosmos DB. By default, the data is encrypted at rest with service-managed keys, but customer-managed keys are commonly required to meet regulatory compliance standards. Customer-managed keys enable the data to be encrypted with an Azure Key Vault key created and owned by you. You have full control and responsibility for the key lifecycle, including rotation and management. Learn more at https://aka.ms/cosmosdb-cmk.

Azure_Security_Benchmark_v2.0 DP-5 Azure_Security_Benchmark_v2.0_DP-5 Azure Security Benchmark DP-5 Data Protection Encrypt sensitive data at rest Shared To complement access controls, data at rest should be protected against ‘out of band’ attacks (such as accessing underlying storage) using encryption. This helps ensure that attackers cannot easily read or modify the data. Azure provides encryption for data at rest by default. For highly sensitive data, you have options to implement additional encryption at rest on all Azure resources where available. Azure manages your encryption keys by default, but Azure provides options to manage your own keys (customer managed keys) for certain Azure services. Understand encryption at rest in Azure: https://docs.microsoft.com/azure/security/fundamentals/encryption-atrest#encryption-at-rest-in-microsoft-cloud-services How to configure customer managed encryption keys: https://docs.microsoft.com/azure/storage/common/storage-encryption-keys-portal Encryption model and key management table: https://docs.microsoft.com/azure/security/fundamentals/encryption-models Data at rest double encryption in Azure: https://docs.microsoft.com/azure/security/fundamentals/double-encryption#data-at-rest n/a link 13
Azure_Security_Benchmark_v3.0 DP-5 Azure_Security_Benchmark_v3.0_DP-5 Microsoft cloud security benchmark DP-5 Data Protection Use customer-managed key option in data at rest encryption when required Shared **Security Principle:** If required for regulatory compliance, define the use case and service scope where customer-managed key option is needed. Enable and implement data at rest encryption using customer-managed key in services. **Azure Guidance:** Azure also provides encryption option using keys managed by yourself (customer-managed keys) for certain services. However, using customer-managed key option requires additional operational efforts to manage the key lifecycle. This may include encryption key generation, rotation, revoke and access control, etc. **Implementation and additional context:** Encryption model and key management table: https://docs.microsoft.com/azure/security/fundamentals/encryption-models Services that support encryption using customer-managed key: https://docs.microsoft.com/azure/security/fundamentals/encryption-models#supporting-services How to configure customer managed encryption keys in Azure Storage: https://docs.microsoft.com/azure/storage/common/storage-encryption-keys-portal n/a link 10

The following points of focus, specifically related to all engagements using the trust services criteria, highlight important characteristics relating to this criterion: • Identifies and Manages the Inventory of Information Assets — The entity identifies, Page 29 TSP Ref. # TRUST SERVICES CRITERIA AND POINTS OF FOCUS inventories, classifies, and manages information assets. • Restricts Logical Access — Logical access to information assets, including hardware, data (at-rest, during processing, or in transmission), software, administrative authorities, mobile devices, output, and offline system components is restricted through the use of access control software and rule sets. • Identifies and Authenticates Users — Persons, infrastructure, and software are identified and authenticated prior to accessing information assets, whether locally or remotely. • Considers Network Segmentation — Network segmentation permits unrelated portions of the entity's information system to be isolated from each other. • Manages Points of Access — Points of access by outside entities and the types of data that flow through the points of access are identified, inventoried, and managed. The types of individuals and systems using each point of access are identified, documented, and managed. • Restricts Access to Information Assets — Combinations of data classification, separate data structures, port restrictions, access protocol restrictions, user identification, and digital certificates are used to establish access-control rules for information assets. • Manages Identification and Authentication — Identification and authentication requirements are established, documented, and managed for individuals and systems accessing entity information, infrastructure, and software. • Manages Credentials for Infrastructure and Software — New internal and external infrastructure and software are registered, authorized, and documented prior to being granted access credentials and implemented on the network or access point. Credentials are removed and access is disabled when access is no longer required or the infrastructure and software are no longer in use. • Uses Encryption to Protect Data — The entity uses encryption to supplement other measures used to protect data at rest, when such protections are deemed appropriate based on assessed risk. • Protects Encryption Keys — Processes are in place to protect encryption keys during generation, storage, use, and destruction 78
