# View all policies

> List the Ranger policies behind data access, search them by name, and filter them by catalog, schema, or table.

The **All policies** tab lists the Ranger policies behind data access. Use it to find the policy that grants a role's
access, or to see every policy that applies to a catalog, schema, or table.

## Prerequisites

Before starting this task, ensure you have the following:

Required roles: `nx1_migration_admin`, `nx1_migration_ops`, or `nx1_migration_user`.

## View all policies

> [tab] Web portal
>
> Perform these steps to view all policies.
>
> 1. Log in to NexusOne.
>
> 2. On the top navigation bar, hover your mouse over **Govern** and then select **Data Access**.
>
> 3. Click the **All policies** tab.
>
> 4. Narrow the list with one or both of the following options:
>
>    * **Search**: In the **Search policies by name** field, enter part of a policy name.
>    * **Catalog, schema, and table**: In the **Catalog** field, select a catalog. Optionally, select a schema and table in the
>      **Schema** and **Table** fields. Then click **Filter**. The table then lists the policies on that resource and any
>      wider policy that covers it. To clear the filter, click **Clear**.
>
> 5. Review the table. It has the following columns:
>
>    * **Name**: The policy name. Click the heading to sort by name.

>    * **Resources**: The catalog, schema, table, or path the policy covers.
>    * **Type**: Whether the policy is **Access**, **Masking**, or **Row Filter**.
>    * **Match**: Appears only when you select a table and click **Filter**. Shows **exact** for a policy on the table, or **broader**
>      for a policy on a wider scope.
>    * **Effect Summary**: Appears only after you click **Filter**. A one-line description of what the policy does.
