Auditing on Synapse workspace should be enabled Auditing on your Synapse workspace should be enabled to track database activities across all databases on the dedicated SQL pools and save them in an audit log. AuditIfNotExists, Disabled 1.0.0
Azure Synapse Analytics dedicated SQL pools should enable encryption Enable transparent data encryption for Azure Synapse Analytics dedicated SQL pools to protect data-at-rest and meet compliance requirements. Please note that enabling transparent data encryption for the pool may impact query performance. More details can refer to https://go.microsoft.com/fwlink/?linkid=2147714 AuditIfNotExists, Disabled 1.0.0
Azure Synapse Workspace SQL Server should be running TLS version 1.2 or newer Setting TLS version to 1.2 or newer improves security by ensuring your Azure Synapse workspace SQL server can only be accessed from clients using TLS 1.2 or newer. Using versions of TLS less than 1.2 is not recommended since they have well documented security vulnerabilities. Audit, Deny, Disabled 1.1.0
Azure Synapse workspaces should allow outbound data traffic only to approved targets Increase security of your Synapse workspace by allowing outbound data traffic only to approved targets. This helps prevention against data exfiltration by validating the target before sending data. Audit, Disabled, Deny 1.0.0
Azure Synapse workspaces should disable public network access Disabling public network access improves security by ensuring that the Synapse workspace isn't exposed on the public internet. Creating private endpoints can limit exposure of your Synapse workspaces. Learn more at: https://docs.microsoft.com/azure/synapse-analytics/security/connectivity-settings. Audit, Deny, Disabled 1.0.0
Azure Synapse workspaces should use customer-managed keys to encrypt data at rest Use customer-managed keys to control the encryption at rest of the data stored in Azure Synapse workspaces. Customer-managed keys deliver double encryption by adding a second layer of encryption on top of the default encryption with service-managed keys. Audit, Deny, Disabled 1.0.0
Azure Synapse workspaces 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 Azure Synapse workspace, data leakage risks are reduced. Learn more about private links at: https://docs.microsoft.com/azure/synapse-analytics/security/how-to-connect-to-workspace-with-private-links. Audit, Disabled 1.0.1
Configure Azure Synapse Workspace Dedicated SQL minimum TLS version Customers can raise or lower the minimal TLS version using the API, for both new Synapse workspaces or existing workspaces. So users who need to use a lower client version in the workspaces can connect while users who has security requirement can raise the minimum TLS version. Learn more at: https://docs.microsoft.com/azure/synapse-analytics/security/connectivity-settings. Modify, Disabled 1.1.0
Configure Azure Synapse workspaces to disable public network access Disable public network access for your Synapse workspace so that it is not accessible over the public internet. This can reduce data leakage risks. Learn more at: https://docs.microsoft.com/azure/synapse-analytics/security/connectivity-settings. Modify, Disabled 1.0.0
Configure Azure Synapse workspaces 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 Azure Synapse workspaces, you can reduce data leakage risks. Learn more about private links at: https://docs.microsoft.com/azure/synapse-analytics/security/how-to-connect-to-workspace-with-private-links. DeployIfNotExists, Disabled 1.0.0
Configure Microsoft Defender for SQL to be enabled on Synapse workspaces Enable Microsoft Defender for SQL on your Azure Synapse workspaces to detect anomalous activities indicating unusual and potentially harmful attempts to access or exploit SQL databases. DeployIfNotExists, Disabled 1.0.0
Configure Synapse workspaces to have auditing enabled To ensure the operations performed against your SQL assets are captured, Synapse workspaces should have auditing enabled. This is sometimes required for compliance with regulatory standards. DeployIfNotExists, Disabled 2.0.0
Configure Synapse workspaces to have auditing enabled to Log Analytics workspace To ensure the operations performed against your SQL assets are captured, Synapse workspaces should have auditing enabled. If auditing is not enabled, this policy will configure auditing events to flow to the specified Log Analytics workspace. DeployIfNotExists, Disabled 1.0.0
Configure Synapse Workspaces to use only Azure Active Directory identities for authentication Azure Active Directory (AAD) only authentication methods improves security by ensuring that Synapse Workspaces exclusively require AAD identities for authentication. Learn more at: https://aka.ms/Synapse. Modify, Disabled 1.0.0
IP firewall rules on Azure Synapse workspaces should be removed Removing all IP firewall rules improves security by ensuring your Azure Synapse workspace can only be accessed from a private endpoint. This configuration audits creation of firewall rules that allow public network access on the workspace. Audit, Disabled 1.0.0
Managed workspace virtual network on Azure Synapse workspaces should be enabled Enabling a managed workspace virtual network ensures that your workspace is network isolated from other workspaces. Data integration and Spark resources deployed in this virtual network also provides user level isolation for Spark activities. Audit, Deny, Disabled 1.0.0
Microsoft Defender for SQL should be enabled for unprotected Synapse workspaces Enable Defender for SQL to protect your Synapse workspaces. Defender for SQL monitors your Synapse SQL to detect anomalous activities indicating unusual and potentially harmful attempts to access or exploit databases. AuditIfNotExists, Disabled 1.0.0
Synapse managed private endpoints should only connect to resources in approved Azure Active Directory tenants Protect your Synapse workspace by only allowing connections to resources in approved Azure Active Directory (Azure AD) tenants. The approved Azure AD tenants can be defined during policy assignment. Audit, Disabled, Deny 1.0.0
Synapse workspace auditing settings should have action groups configured to capture critical activities To ensure your audit logs are as thorough as possible, the AuditActionsAndGroups property should include all the relevant groups. We recommend adding at least SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP, FAILED_DATABASE_AUTHENTICATION_GROUP, and BATCH_COMPLETED_GROUP. This is sometimes required for compliance with regulatory standards. AuditIfNotExists, Disabled 1.0.0
Synapse Workspaces should use only Azure Active Directory identities for authentication Azure Active Directory (AAD) only authentication methods improves security by ensuring that Synapse Workspaces exclusively require AAD identities for authentication. Learn more at: https://aka.ms/Synapse. Audit, Deny, Disabled 1.0.0
Synapse workspaces with SQL auditing to storage account destination should be configured with 90 days retention or higher For incident investigation purposes, we recommend setting the data retention for your Synapse workspace' SQL auditing to storage account destination to at least 90 days. Confirm that you are meeting the necessary retention rules for the regions in which you are operating. This is sometimes required for compliance with regulatory standards. AuditIfNotExists, Disabled 2.0.0
Vulnerability assessment should be enabled on your Synapse workspaces Discover, track, and remediate potential vulnerabilities by configuring recurring SQL vulnerability assessment scans on your Synapse workspaces. AuditIfNotExists, Disabled 1.0.0
