Databricks Unity Catalog Audit Logs

Query audit for Databricks Unity Catalog captures user data access within Unity Catalog and presents them in a universal format as Immuta audit logs. Multiple access options are supported for audit:

• Cluster queries with the following supported languages: SQL, Scala, Python, and R.

• SQL warehouse queries

Immuta audits the activity of all Unity Catalog users and tables.

Requirement

Databricks Unity Catalog integration with query audit enabled

Store audit logs

By default Immuta audit logs expire after 7 days. Export the universal audit model (UAM) logs to S3 or ADLS Gen 2, and store audit logs outside of Immuta in order to retain the audit logs long-term.

Audit frequency

Immuta collects audit records once an hour by default, and the frequency can be changed at any time from the Immuta app settings page. The frequency is a global setting based on integration type, so organizations with multiple Databricks Unity Catalog integrations will have the same audit frequency for all of them. The more frequent the audit records are ingested, the more current the audit records. However, there could be performance and cost impacts from the frequent jobs because Immuta will start a Databricks cluster to complete the audit ingest job if one is not already running.

To manually prompt the query audit, click Load Audit Events on the Immuta audit page.

Audit schema

Each audit message from the Immuta platform will be a one-line JSON object containing the properties listed below.

Property	Description	Example

auditPayload.technologyContext.host	The Unity Catalog host.	deployment-name.cloud.databricks.com
auditPayload.technologyContext.clientIp	The IP address of the Spark cluster the request is coming from.	0.0.0.0
auditPayload.technologyContext.queryLanguage	The queryLanguage corresponds to the programming language used: SQL, Python, Scala, or R. Audited JDBC queries will indicate that it came from JDBC here.	python
auditPayload.objectsAccessed	The Unity Catalog objects accessed.	[]
auditPayload.securityProfile.sensitivity.score	The sensitivity score of the query. Classification must be configured for this field.	INDETERMINATE
auditPayload.version	The version of the audit event schema.	1
receivedTimestamp	The timestamp of when the audit event was received and stored by Immuta.	2023-06-27T15:18:22.314Z

Limitations

• Enrichment of audit logs with Immuta entitlements information is not supported. While you will see these entitlements in the Databricks Spark audit logs, the following will not be in the query audit for Unity Catalog:

  • Immuta policies information

  • User attributes

  • Groups

• Immuta determines unauthorized events based on error messages within Unity Catalog records. When the error messages contain expected language, unauthorized events will be available for query audit for Unity Catalog. In other cases, it is not possible to determine the cause of an error.

• Audit for cluster queries do not support UNAUTHORIZED status. If a cluster query is unauthorized, it will show FAILURE.

• Data source information will be provided when available:

  • For some queries, Databricks Unity Catalog does not report the target data source for the data access operation. In these cases the activity is audited, yet the audit record in Immuta will not include the target data source information.

  • Data source information is not available for unauthorized queries and events.

• Column information from the query is not currently supported.

• Immuta audit records include unregistered data sources and users; however, activity from them will not appear in any governance reports.
