Content Access Control

This module allows you to create arbitrary Workflows, and assign them to Entities.

Workflows are made up of workflow states. Transitions between states can be allowed per role. For example, a workflow with the states Draft, Review, and Published could be assigned to the Story node type. Only users with role 'chief editor' can set Stories to the published state.
You can set up the Workflow to alter states from form, page, comment, a special block, and a special workflow tab.
Additionally, the submodule Workflow Access allows you to manage view/edit/delete permissions for content types per User role and Workflow state.

A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can. The CAPTCHA module provides this feature to virtually any user facing web form on a Drupal site.

Co-maintainer wanted

We do this our spare time, which is unfortunately almost nonexistent at the moment due to real life obligations. To give the CAPTCHA module the required level of maintenance, an extra co-maintainer would be welcome. If you're interested in helping with this very popular module, please contact me or open an issue in the CAPTCHA module issue tracker.

Access control for user roles based on taxonomy categories (vocabulary, terms).

Manage which roles can view, edit, and/or delete nodes by content type (default) or on a per-node basis (overriding defaults on each node).

Also supports changing permissions using Actions.

This module is similar in function to Content Access with ACL.

This module allows administrators to make some nodes private and/or editable by certain user roles.

The Path Access module gives site administrators an additional layer of access control to all pages of a Drupal site.

This node_access module governs access to nodes based on the taxonomy terms applied to the nodes. A simple scheme based on taxonomy, roles and users controls which content is visible.

This module changes your forum administration page to allow you to set forums private. You can control what user roles can view, edit, delete, and post to each forum. You can also give each forum a list of users who have administrative access on that forum (AKA moderators).

This module requires the ACL module in order to function. The D7 version also requires the Chain Menu Access API 2.x module.

Forum Access is compatible with the core Forum module, Advanced Forum, and Content Access, Domain Access as well as all other well-behaved node access modules.

The ACL module, short for Access Control Lists, is an API for other modules to create lists of users and give them access to nodes. It has no UI of its own and will not do anything by itself; install this module only if some other module tells you to.

We're aware of the following modules using ACL (let us know if you know of others):

• Content Access (optionally uses ACL to provide by-user access control)
• Flexi Access
• Forum Access
• Image Gallery Access

Nodeaccess is a Drupal access control module which provides view, edit and delete access to nodes. Users with the 'grant node permissions' permission will have a grant tab on node pages which allows them to grant access to that node by user or role. Administrators can set default access controls per content type, and also define which roles are available to grant permissions to on the node grants tab.
