[Preview]: Cosmos Database Accounts should be Zone Redundant Cosmos Database Accounts can be configured to be Zone Redundant or not. If the 'enableMultipleWriteLocations' is set to 'true' then all locations must have a 'isZoneRedundant' property and it must be set to 'true'. If the 'enableMultipleWriteLocations' is set to 'false' then the primary location ('failoverPriority' set to 0) must have a 'isZoneRedundant' property and it must be set to 'true'. Enforcing this policy ensures Cosmos Database Accounts are appropriately configured for zone redundancy. Audit, Deny, Disabled 1.0.0-preview
Azure Cosmos DB accounts should have firewall rules Firewall rules should be defined on your Azure Cosmos DB accounts to prevent traffic from unauthorized sources. Accounts that have at least one IP rule defined with the virtual network filter enabled are deemed compliant. Accounts disabling public access are also deemed compliant. Audit, Deny, Disabled 2.0.0
Azure Cosmos DB accounts should not exceed the maximum number of days allowed since last account key regeneration. Regenerate your keys in the specified time to keep your data more protected. Audit, Disabled 1.0.0
Azure Cosmos DB accounts should use customer-managed keys to encrypt data at rest 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. audit, Audit, deny, Deny, disabled, Disabled 1.1.0
Azure Cosmos DB allowed locations This policy enables you to restrict the locations your organization can specify when deploying Azure Cosmos DB resources. Use to enforce your geo-compliance requirements. [parameters('policyEffect')] 1.1.0
Azure Cosmos DB key based metadata write access should be disabled This policy enables you to ensure all Azure Cosmos DB accounts disable key based metadata write access. append 1.0.0
Azure Cosmos DB should disable public network access Disabling public network access improves security by ensuring that your CosmosDB account isn't exposed on the public internet. Creating private endpoints can limit exposure of your CosmosDB account. Learn more at: https://docs.microsoft.com/azure/cosmos-db/how-to-configure-private-endpoints#blocking-public-network-access-during-account-creation. Audit, Deny, Disabled 1.0.0
Azure Cosmos DB throughput should be limited This policy enables you to restrict the maximum throughput your organization can specify when creating Azure Cosmos DB databases and containers through the resource provider. It blocks the creation of autoscale resources. audit, Audit, deny, Deny, disabled, Disabled 1.1.0
Configure Cosmos DB database accounts to disable local authentication Disable local authentication methods so that your Cosmos DB database accounts exclusively require Azure Active Directory identities for authentication. Learn more at: https://docs.microsoft.com/azure/cosmos-db/how-to-setup-rbac#disable-local-auth. Modify, Disabled 1.1.0
Configure CosmosDB accounts to disable public network access Disable public network access for your CosmosDB resource so that it's not accessible over the public internet. This can reduce data leakage risks. Learn more at: https://docs.microsoft.com/azure/cosmos-db/how-to-configure-private-endpoints#blocking-public-network-access-during-account-creation. Modify, Disabled 1.0.1
Configure CosmosDB accounts with private endpoints Private endpoints connect your virtual network to Azure services without a public IP address at the source or destination. By mapping private endpoints to your CosmosDB account, you can reduce data leakage risks. Learn more about private links at: https://docs.microsoft.com/azure/cosmos-db/how-to-configure-private-endpoints. DeployIfNotExists, Disabled 1.0.0
Cosmos DB database accounts should have local authentication methods disabled Disabling local authentication methods improves security by ensuring that Cosmos DB database accounts exclusively require Azure Active Directory identities for authentication. Learn more at: https://docs.microsoft.com/azure/cosmos-db/how-to-setup-rbac#disable-local-auth. Audit, Deny, Disabled 1.1.0
Cosmos DB should use a virtual network service endpoint This policy audits any Cosmos DB not configured to use a virtual network service endpoint. Audit, Disabled 1.0.0
CosmosDB accounts should use private link Azure Private Link lets you connect your virtual network to Azure services without a public IP address at the source or destination. The Private Link platform handles the connectivity between the consumer and services over the Azure backbone network. By mapping private endpoints to your CosmosDB account, data leakage risks are reduced. Learn more about private links at: https://docs.microsoft.com/azure/cosmos-db/how-to-configure-private-endpoints. Audit, Disabled 1.0.0
Deploy Advanced Threat Protection for Cosmos DB Accounts This policy enables Advanced Threat Protection across Cosmos DB accounts. DeployIfNotExists, Disabled 1.0.0
Enable logging by category group for Azure Cosmos DB (microsoft.documentdb/databaseaccounts) to Log Analytics Resource logs should be enabled to track activities and events that take place on your resources and give you visibility and insights into any changes that occur. This policy deploys a diagnostic setting using a category group to route logs to a Log Analytics workspace for Azure Cosmos DB (microsoft.documentdb/databaseaccounts). DeployIfNotExists, AuditIfNotExists, Disabled 1.0.0
