Security

Implements Project Honey Pot's http:BL service for Drupal. http:BL can prevent email address harvesters and comment spammers from visiting your site by using a centralized DNS blacklist. It requires a free Project Honey Pot membership. This module provides efficient blacklist lookups and blocks malicious visitors effectively.

httpBL has been adopted for use to enhance protection on Drupal.org.

Finds all external links on a web page and adds an "external" icon to the link indicating it will take the user offsite or a "mail" icon for mailto: links.

This module allows users to flag nodes and comments as offensive for the adminstrator to review.

This module is in the rearchitecting period. All changes will happen in 2.x branch.

The admin can specify which type of nodes are allowed to be flagged.

Permissions
There are 3 permissions - administer abuse reports, flag content, and direct flag content. Administer abuse reports allows a user to see which nodes have been flagged and allows them to either remove from the site or allow back into the system. Flag content allows a user to flag content. Direct flag allows a user to flag a content and set the content as 'hidden'. In essence, it is a person who has been trusted to flag genuinely bad content to be removed without requiring multiple users to flag the content before the system hides it.

Content Status

This module allows the site administrator to allow new account registrations only for users who provide a valid registration code.

This module also allows the management of these registration codes, including listing, generating, importing and exporting.

The most common use of this module is medallion based registration - only users who have purchased a membership medallion (e.g. made a physical purchase entitling them) are able to register.

Other uses include promotional codes, and shared private key registration.

This module allows for sub-modules which extend the functionality of the core module, this includes:

• mailer: allows registration codes to be emailed to lists of email addresses
• roles: automates role assignment during registration based on code used
• voucher: allows registration codes to be used as a voucher after registration
• og: integration with organic groups, for group assignment during the registration process
• dynamic: allows on-the-fly creation of registration codes that match a validation criteria.
• ie: provides import and export functionality.
