## Command overview: `immuta sdd`

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

| Subcommands                                                                                            | Description                                           |

| [`run`](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/sdd.md)                | Run SDD on specific data sources or all data sources. |
| [`template`](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/templates.md)     | Manage SDD frameworks.                                |

## SDD workflow

Two common workflows for using SDD are outlined below. The first illustrates how to apply a global framework to all data sources, while the second outlines how users can create and apply frameworks 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](/2024.2/discover-your-data/data-discovery.md).

### Workflow 1: Apply the global framework to all data sources

1. Data governor [creates a framework](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/templates.md#create-an-identification-framework) using one or more rules.
2. [System administrator adds this framework as the global framework so that it applies to all data sources](/2024.2/discover-your-data/data-discovery/how-to-guides/global-sdd.md).
3. [Users trigger SDD on data sources](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/sdd.md).

### Workflow 2: Apply a framework to a specific data source

1. Data governor creates one or more [rules with patterns](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/classifiers.md#create-a-rule).
2. [Data owner creates a framework containing one or more rules](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/templates.md#create-an-identification-framework).
3. [Data owner triggers SDD on one or more data sources](/2024.2/developer-guides/the-immuta-cli/manage-sensitive-data-discovery/sdd.md) and resulting tags are applied to columns where criteria were met and patterns were recognized.
