ExtendedServerBlobAuditingPolicy interface

Specifies the Actions-Groups and Actions to audit.

The recommended set of action groups to use is the following combination - this will audit all the queries and stored procedures executed against the database, as well as successful and failed logins:

BATCH_COMPLETED_GROUP, SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP, FAILED_DATABASE_AUTHENTICATION_GROUP.

This above combination is also the set that is configured by default when enabling auditing from the Azure portal.

The supported action groups to audit are (note: choose only specific groups that cover your auditing needs. Using unnecessary groups could lead to very large quantities of audit records):

APPLICATION_ROLE_CHANGE_PASSWORD_GROUP BACKUP_RESTORE_GROUP DATABASE_LOGOUT_GROUP DATABASE_OBJECT_CHANGE_GROUP DATABASE_OBJECT_OWNERSHIP_CHANGE_GROUP DATABASE_OBJECT_PERMISSION_CHANGE_GROUP DATABASE_OPERATION_GROUP DATABASE_PERMISSION_CHANGE_GROUP DATABASE_PRINCIPAL_CHANGE_GROUP DATABASE_PRINCIPAL_IMPERSONATION_GROUP DATABASE_ROLE_MEMBER_CHANGE_GROUP FAILED_DATABASE_AUTHENTICATION_GROUP SCHEMA_OBJECT_ACCESS_GROUP SCHEMA_OBJECT_CHANGE_GROUP SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP SCHEMA_OBJECT_PERMISSION_CHANGE_GROUP SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP USER_CHANGE_PASSWORD_GROUP BATCH_STARTED_GROUP BATCH_COMPLETED_GROUP

These are groups that cover all sql statements and stored procedures executed against the database, and should not be used in combination with other groups as this will result in duplicate audit logs.

For more information, see Database-Level Audit Action Groups.

For Database auditing policy, specific Actions can also be specified (note that Actions cannot be specified for Server auditing policy). The supported actions to audit are: SELECT UPDATE INSERT DELETE EXECUTE RECEIVE REFERENCES

The general form for defining an action to be audited is: {action} ON {object} BY {principal}

Note that in the above format can refer to an object like a table, view, or stored procedure, or an entire database or schema. For the latter cases, the forms DATABASE::{db_name} and SCHEMA::{schema_name} are used, respectively.

For example: SELECT on dbo.myTable by public SELECT on DATABASE::myDatabase by public SELECT on SCHEMA::mySchema by public

auditActionsAndGroups?: string[]

Property Value

Specifies whether audit events are sent to Azure Monitor. In order to send the events to Azure Monitor, specify 'state' as 'Enabled' and 'isAzureMonitorTargetEnabled' as true.

When using REST API to configure auditing, Diagnostic Settings with 'SQLSecurityAuditEvents' diagnostic logs category on the database should be also created. Note that for server level audit you should use the 'master' database as {databaseName}.

Diagnostic Settings URI format: PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Sql/servers/{serverName}/databases/{databaseName}/providers/microsoft.insights/diagnosticSettings/{settingsName}?api-version=2017-05-01-preview

For more information, see Diagnostic Settings REST API or Diagnostic Settings PowerShell

isAzureMonitorTargetEnabled?: boolean

Property Value

Specifies the state of devops audit. If state is Enabled, devops logs will be sent to Azure Monitor. In order to send the events to Azure Monitor, specify 'State' as 'Enabled', 'IsAzureMonitorTargetEnabled' as true and 'IsDevopsAuditEnabled' as true

When using REST API to configure auditing, Diagnostic Settings with 'DevOpsOperationsAudit' diagnostic logs category on the master database should also be created.

Diagnostic Settings URI format: PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Sql/servers/{serverName}/databases/master/providers/microsoft.insights/diagnosticSettings/{settingsName}?api-version=2017-05-01-preview

isDevopsAuditEnabled?: boolean

Property Value

Specifies whether storageAccountAccessKey value is the storage's secondary key.

isStorageSecondaryKeyInUse?: boolean

Property Value

Specifies condition of where clause when creating an audit.

predicateExpression?: string

Property Value

Specifies the amount of time in milliseconds that can elapse before audit actions are forced to be processed. The default minimum value is 1000 (1 second). The maximum is 2,147,483,647.

queueDelayMs?: number

Property Value

Specifies the number of days to keep in the audit logs in the storage account.

retentionDays?: number

Property Value

Specifies the state of the policy. If state is Enabled, storageEndpoint or isAzureMonitorTargetEnabled are required.

state?: BlobAuditingPolicyState

Property Value

Specifies the identifier key of the auditing storage account. If state is Enabled and storageEndpoint is specified, not specifying the storageAccountAccessKey will use SQL server system-assigned managed identity to access the storage. Prerequisites for using managed identity authentication:

1. Assign SQL Server a system-assigned managed identity in Azure Active Directory (AAD).
2. Grant SQL Server identity access to the storage account by adding 'Storage Blob Data Contributor' RBAC role to the server identity. For more information, see Auditing to storage using Managed Identity authentication

storageAccountAccessKey?: string

Property Value

Specifies the blob storage subscription Id.

storageAccountSubscriptionId?: string

Property Value

Specifies the blob storage endpoint (e.g. https://MyAccount.blob.core.windows.net). If state is Enabled, storageEndpoint or isAzureMonitorTargetEnabled is required.

storageEndpoint?: string

Property Value

Fully qualified resource ID for the resource. Ex - /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/{resourceProviderNamespace}/{resourceType}/{resourceName} NOTE: This property will not be serialized. It can only be populated by the server.

id?: string

Property Value

Inherited From ProxyResource.id

The name of the resource NOTE: This property will not be serialized. It can only be populated by the server.

name?: string

Property Value

Inherited From ProxyResource.name

The type of the resource. E.g. "Microsoft.Compute/virtualMachines" or "Microsoft.Storage/storageAccounts" NOTE: This property will not be serialized. It can only be populated by the server.

type?: string

Property Value

Inherited From ProxyResource.type
