AppBuilder (FAB), an application development framework |
| built on top of Flask. FAB provides authentication, user management, permissions and roles. |
| Please read its <a href="https://flask-appbuilder.readthedocs.io/en/latest/security.html" target="_blank" rel="noopener noreferrer">Security documentation</a>.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="provided-roles">Provided Roles<a class="hash-link" href="#provided-roles" title="Direct link to heading"></a></h3><p>Superset ships with a set of roles that are handled by Superset itself. You can assume |
| that these roles will stay up-to-date as Superset evolves (and as you update Superset versions).</p><p>Even though <strong>Admin</strong> users have the ability, we don't recommend altering the |
| permissions associated with each role (e.g. by removing or adding permissions to them). The permissions |
| associated with each role will be re-synchronized to their original values when you run |
| the <strong>superset init</strong> command (often done between Superset versions).</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="admin">Admin<a class="hash-link" href="#admin" title="Direct link to heading"></a></h3><p>Admins have all possible rights, including granting or revoking rights from other |
| users and altering other people’s slices and dashboards.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="alpha">Alpha<a class="hash-link" href="#alpha" title="Direct link to heading"></a></h3><p>Alpha users have access to all data sources, but they cannot grant or revoke access |
| from other users. They are also limited to altering the objects that they own. Alpha users can add and alter data sources.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="gamma">Gamma<a class="hash-link" href="#gamma" title="Direct link to heading"></a></h3><p>Gamma users have limited access. They can only consume data coming from data sources |
| they have been given access to through another complementary role. They only have access to |
| view the slices and dashboards made from data sources that they have access to. Currently Gamma |
| users are not able to alter or add data sources. We assume that they are mostly content consumers, though they can create slices and dashboards.</p><p>Also note that when Gamma users look at the dashboards and slices list view, they will |
| only see the objects that they have access to.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="sql_lab">sql_lab<a class="hash-link" href="#sql_lab" title="Direct link to heading"></a></h3><p>The <strong>sql_lab</strong> role grants access to SQL Lab. Note that while <strong>Admin</strong> users have access |
| to all databases by default, both <strong>Alpha</strong> and <strong>Gamma</strong> users need to be given access on a per database basis.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="public">Public<a class="hash-link" href="#public" title="Direct link to heading"></a></h3><p>To allow logged-out users to access some Superset features, you can use the <code>PUBLIC_ROLE_LIKE</code> config setting and assign it to another role whose permissions you want passed to this role.</p><p>For example, by setting <code>PUBLIC_ROLE_LIKE = "Gamma"</code> in your <code>superset_config.py</code> file, you grant |
| public role the same set of permissions as for the <strong>Gamma</strong> role. This is useful if one |
| wants to enable anonymous users to view dashboards. Explicit grant on specific datasets is |
| still required, meaning that you need to edit the <strong>Public</strong> role and add the public data sources to the role manually.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="managing-data-source-access-for-gamma-roles">Managing Data Source Access for Gamma Roles<a class="hash-link" href="#managing-data-source-access-for-gamma-roles" title="Direct link to heading"></a></h3><p>Here’s how to provide users access to only specific datasets. First make sure the users with |
| limited access have <!-- -->[only]<!-- --> the Gamma role assigned to them. Second, create a new role (Menu -> Security -> List Roles) and click the + sign.</p><p>This new window allows you to give this new role a name, attribute it to users and select the |
| tables in the <strong>Permissions</strong> dropdown. To select the data sources you want to associate with this role, simply click on the dropdown and use the typeahead to search for your table names.</p><p>You can then confirm with users assigned to the <strong>Gamma</strong> role that they see the |
| objects (dashboards and slices) associated with the tables you just extended them.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="customizing-permissions">Customizing Permissions<a class="hash-link" href="#customizing-permissions" title="Direct link to heading"></a></h3><p>The permissions exposed by FAB are very granular and allow for a great level of |
| customization. FAB creates many permissions automagically for each model that is |
| created (can_add, can_delete, can_show, can_edit, …) as well as for each view. |
| On top of that, Superset can expose more granular permissions like <strong>all_datasource_access</strong>.</p><p><strong>We do not recommend altering the 3 base roles as there are a set of assumptions that |
| Superset is built upon</strong>. It is possible though for you to create your own roles, and union them to existing ones.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="permissions">Permissions<a class="hash-link" href="#permissions" title="Direct link to heading"></a></h3><p>Roles are composed of a set of permissions, and Superset has many categories of |
| permissions. Here are the different categories of permissions:</p><ul><li>Model & Action: models are entities like Dashboard, Slice, or User. Each model has |
| a fixed set of permissions, like <strong>can_edit</strong>, <strong>can_show</strong>, <strong>can_delete</strong>, <strong>can_list</strong>, <strong>can_add</strong>, |
| and so on. For example, you can allow a user to delete dashboards by adding <strong>can_delete</strong> on |
| Dashboard entity to a role and granting this user that role.</li><li>Views: views are individual web pages, like the Explore view or the SQL Lab view. |
| When granted to a user, they will see that view in its menu items, and be able to load that page.</li><li>Data source: For each data source, a permission is created. If the user does not have the |
| <code>all_datasource_access permission</code> granted, the user will only be able to see Slices or explore the data sources that are granted to them</li><li>Database: Granting access to a database allows for the user to access all |
| data sources within that database, and will enable the user to query that |
| database in SQL Lab, provided that the SQL Lab specific permission have been granted to the user</li></ul><h3 class="anchor anchorWithStickyNavbar_mojV" id="restricting-access-to-a-subset-of-data-sources">Restricting Access to a Subset of Data Sources<a class="hash-link" href="#restricting-access-to-a-subset-of-data-sources" title="Direct link to heading"></a></h3><p>We recommend giving a user the <strong>Gamma</strong> role plus any other roles that would add |
| access to specific data sources. We recommend that you create individual roles for |
| each access profile. For example, the users on the Finance team might have access to a set of |
| databases and data sources; these permissions can be consolidated in a single role. |
| Users with this profile then need to be assigned the <strong>Gamma</strong> role as a foundation to |
| the models and views they can access, and that Finance role that is a collection of permissions to data objects.</p><p>A user can have multiple roles associated with them. For example, an executive on the Finance |
| team could be granted <strong>Gamma</strong>, <strong>Finance</strong>, and the <strong>Executive</strong> roles. The <strong>Executive</strong> |
| role could provide access to a set of data sources and dashboards made available only to executives. |
| In the <strong>Dashboards</strong> view, a user can only see the ones they have access too |
| based on the roles and permissions that were attributed.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="row-level-security">Row Level Security<a class="hash-link" href="#row-level-security" title="Direct link to heading"></a></h3><p>Using Row Level Security filters (under the <strong>Security</strong> menu) you can create filters |
| that are assigned to a particular table, as well as a set of roles. |
| If you want members of the Finance team to only have access to |
| rows where <code>department = "finance"</code>, you could:</p><ul><li>Create a Row Level Security filter with that clause (<code>department = "finance"</code>)</li><li>Then assign the clause to the <strong>Finance</strong> role and the table it applies to</li></ul><p>The <strong>clause</strong> field, which can contain arbitrary text, is then added to the generated |
| SQL statement’s WHERE clause. So you could even do something like create a filter |
| for the last 30 days and apply it to a specific role, with a clause |
| like <code>date_field > DATE_SUB(NOW(), INTERVAL 30 DAY)</code>. It can also support |
| multiple conditions: <code>client_id = 6</code> AND <code>advertiser="foo"</code>, etc.</p><p>All relevant Row level security filters will be combined together (under the hood, |
| the different SQL clauses are combined using AND statements). This means it's |
| possible to create a situation where two roles conflict in such a way as to limit a table subset to empty.</p><p>For example, the filters <code>client_id=4</code> and <code>client_id=5</code>, applied to a role, |
| will result in users of that role having <code>client_id=4</code> AND <code>client_id=5</code> |
| added to their query, which can never be true.</p><h3 class="anchor anchorWithStickyNavbar_mojV" id="reporting-security-vulnerabilities">Reporting Security Vulnerabilities<a class="hash-link" href="#reporting-security-vulnerabilities" title="Direct link to heading"></a></h3><p>Apache Software Foundation takes a rigorous standpoint in annihilating the security issues in its |
| software projects. Apache Superset is highly sensitive and forthcoming to issues pertaining to its |
| features and functionality.</p><p>If you have apprehensions regarding Superset security or you discover vulnerability or potential |
| threat, don’t hesitate to get in touch with the Apache Security Team by dropping a mail at |
| <a href="mailto:security@apache.org." target="_blank" rel="noopener noreferrer">security@apache.org.</a> In the mail, specify the project name Superset with the description of the |
| issue or potential threat. You are also urged to recommend the way to reproduce and replicate the |
| issue. The security team and the Superset community will get back to you after assessing and |
| analysing the findings.</p><p>PLEASE PAY ATTENTION to report the security issue on the security email before disclosing it on |
| public domain. The ASF Security Team maintains a page with the description of how vulnerabilities |
| and potential threats are handled, check their web page for more details.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/superset/tree/master/docs/docs/security.mdx" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_dcUD" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div><div class="col lastUpdated_foO9"></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages navigation"><div class="pagination-nav__item"><a class="pagination-nav__link" href="/docs/api"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">API</div></a></div><div class="pagination-nav__item pagination-nav__item--next"></div></nav></div></div><div class="col col--3"><div class="tableOfContents_cNA8 thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#roles" class="table-of-contents__link toc-highlight">Roles</a></li><li><a href="#provided-roles" class="table-of-contents__link toc-highlight">Provided Roles</a></li><li><a href="#admin" class="table-of-contents__link toc-highlight">Admin</a></li><li><a href="#alpha" class="table-of-contents__link toc-highlight">Alpha</a></li><li><a href="#gamma" class="table-of-contents__link toc-highlight">Gamma</a></li><li><a href="#sql_lab" class="table-of-contents__link toc-highlight">sql_lab</a></li><li><a href="#public" class="table-of-contents__link toc-highlight">Public</a></li><li><a href="#managing-data-source-access-for-gamma-roles" class="table-of-contents__link toc-highlight">Managing Data Source Access for Gamma Roles</a></li><li><a href="#customizing-permissions" class="table-of-contents__link toc-highlight">Customizing Permissions</a></li><li><a href="#permissions" class="table-of-contents__link toc-highlight">Permissions</a></li><li><a href="#restricting-access-to-a-subset-of-data-sources" class="table-of-contents__link toc-highlight">Restricting Access to a Subset of Data Sources</a></li><li><a href="#row-level-security" class="table-of-contents__link toc-highlight">Row Level Security</a></li><li><a href="#reporting-security-vulnerabilities" class="table-of-contents__link toc-highlight">Reporting Security Vulnerabilities</a></li></ul></div></div></div></div></main></div></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="footer__bottom text--center"><div class="footer__copyright">Copyright © 2022, |
