Data
====

This section provides access to security settings related to data management and :ref:`security_layer`. Data access is granted to roles, and roles are granted to users and groups.

Rules
-----

There are two rules available by default, but they don't provide any restrictions on access by default. The first rule ``*.*.r``, applied to all roles, states that any operation in any resource in any workspace can be read. The second rule, ``*.*.w``, also applied to all roles, says the same for write access.

   *Rules for data access*

Clicking an existing rule will open it for editing, while clicking the :guilabel:`Add a new rule` link will create a new rule.

   * - Option
     - Description

     - If checked, switches the editor to create/edit a rule about a global layer group (and will remove the layer configuration as a result)
   * - Workspace
     - Sets the allowed workspace for this rule. Options are ``*`` (all workspaces), or the name of each workspace.
   * - Layer and groups
     - Sets the allowed layer/groups for this rule. Options are ``*`` (all layers/groups in the chosen workspace), or the name of each layer in the above workspace. Will be disabled until the workspace is set.
   * - Access mode
     - Specifies whether the rule refers to either ``Read`` or ``Write`` mode
   * - Grant access to any role
     - If selected, the rule will apply to all roles, with no need to specify
   * - Role list
     - Full list of roles, including a list of roles to which the rule is associated. Association can be toggled here via the arrow buttons. This option is not applied if :guilabel:`Grant access to any role` is checked.
   * - Add a new role
     - Shortcut to adding a new role

Catalog Mode
------------

This mode configures how GeoServer will advertise secured layers and behave when a secured layer is accessed without the necessary privileges. There are three options:  :guilabel:`HIDE`, :guilabel:`MIXED`, and :guilabel:`CHALLENGE`. For further information on these options, please see the section on :ref:`security_layer`.
