# Manage Rules

**Requirements**:

* SDD enabled and [turned on](/2024.2/application-settings/how-to-guides/config-builder-guide.md#enable-sensitive-data-discovery)
* Immuta permission `GOVERNANCE`

## Create a rule

You can only have one rule per pattern in the framework. If you do not see the pattern for the rule you want to create, then it already has a rule built off of it.

1. Click the **Discover** icon in the navigation menu and select the **Framework** tab.
2. Select the framework you want to edit and navigate to the **Discovery Rules** tab.
3. Click **Create New**.
4. Select the **Tags to apply** from the dropdown. The tags you select are the tags applied when the pattern is matched. *Note that resulting tags must be under the Discovered parent tag and cannot be parent tags themselves unless they have already been manually applied to a data source.*
5. Select the **Criteria type** from the dropdown. See the [overview page for more information about the criteria types](/2024.2/discover-your-data/data-discovery.md#criteria).
   1. Competitive pattern analysis is for regex and dictionary patterns.
   2. Column name is for column name patterns.
6. Select the **Pattern** from the dropdown.
7. Click **Create Rule**.

## Edit a rule

1. Click the **Discover** icon in the navigation menu and select the **Frameworks** tab.
2. Select the framework of the rule you want to edit and navigate to the **Discovery Rules** tab.
3. Select the rule you want to edit.
4. Click **Edit**.
5. Edit the field you want to change. Note any field shadowed is not editable, and the rule must be deleted and re-created to change them.
6. Click **Save**.

## Delete a rule

Deleting a rule removes the tags once applied by that rule the next time SDD runs on a data source. To delete a rule,

1. Click the **Discover** icon in the navigation menu and select the **Frameworks** tab.
2. Select the framework you want to edit and navigate to the **Discovery Rules** tab.
3. Click the three dot menu in the **Action** column for the rule you want to delete.
4. Select **Remove**.
5. Click **Confirm**.
