Customize and Manage Sensitive Data Discovery


In previous documentation, identifier is referred to as classifier. The language is being updated to identifier to be more accurate and not conflate meaning with the Immuta data classification and frameworks feature.

This command allows you to customize and run SDD in your instance of Immuta. The table below illustrates subcommands and arguments.

SDD workflow

Two common workflows for using SDD are outlined below. The first illustrates how to apply a single global template to all data sources, while the second outlines how users can create and apply templates to data sources they own.

The tutorials linked below show how to use the CLI to complete this workflow. For an overview of how sensitive data discovery works, see this overview.

Workflow 1: Apply a global template to all data sources

  1. Data governor creates a template using one or more built-in or custom identifiers.
  2. System administrator adds this template to the global settings so that it applies to all data sources.
  3. Users trigger SDD on data sources.

Workflow 2: Apply a template to a specific data source

  1. Data governor creates one or more custom identifiers.
  2. Data owner creates a template containing one or more identifiers.
  3. Data owner triggers SDD on one or more data sources, and tags are applied to columns where the identifier was detected.
