  4. SAT Dashboard: The prebuilt SAT dashboard shows the newest scan outcomes pulled from the Delta desk. Directors, safety analysts, and auditors can now assess their Databricks safety posture from the consolation of a single display screen.

SAT deployment particulars

SAT setup and utilization might be damaged into three phases, as proven within the diagram under (Determine 3).

Determine 3. SAT Deployment Particulars
  1. Deployment and Configuration
    SAT Setup requires admin privileges and entails the next actions:
    • In a selected workspace, the admin makes use of a sequence of notebooks for the preliminary one-time setup as documented right here.
    • All checks within the listing are enabled by default, however an admin can flip off any that are not obligatory

For instance, the ‘cluster coverage not used’ will present a listing of the cluster workloads the place the coverage isn’t utilized, avoiding a needle-in-a-haystack state of affairs.

The right way to use SAT for danger mitigation

Safety Evaluation Instrument (SAT) analyzes 37 finest practices, with extra on the best way, and presents the insights in a dashboard. What do you do with these insights? We are going to use two examples for example how a typical consumer would make use of the insights.

Within the first instance, the SAT scan highlights one discovering that surfaces a possible danger – the crimson test mark in Determine 5. The Deprecated runtime variations test is crimson indicating that there are runtimes which are deprecated. Workloads on unsupported runtime variations could proceed to run, however they obtain no Databricks assist or fixes. The “test id” related to the discovering can be utilized within the “Further Particulars” part to question for extra detailed info on what configuration setting or management failed a selected finest follow rule. For instance, the picture under showcases further particulars on the “Deprecated runtime variations” danger for directors to research. The Remediation column within the screenshot describes the chance and remediation actions wanted with hyperlinks to the documentation of the Databricks runtime variations which are at the moment supported. The consumer ought to take the advisable remediation motion in a well timed method commensurate with the severity of the discovering.

Within the second instance, we spotlight one discovering that meets Databricks’ finest practices – the inexperienced test mark in Determine 5. The Log supply test is inexperienced, confirming that the workspace follows Databricks safety finest practices. Once more, the “test id” (“GOV-3”) can be utilized within the “Further particulars” part to get detailed info. No additional motion is required, however we suggest the consumer to run these checks often to view Databricks account workspace safety and guarantee steady enchancment comprehensively.
