Simple IP acl

This module uses a few of variables in settings.php to configure environment dependent access list by origin IP.
Use it to limit access to sensitive URLs to only certain IPs (e.g., your office).

The module throws a very unsexy and un-meaningful error message which will be useless for unwanted visitors, but will allow developers and site owners to understand why they are getting it.

This module is perfect to quickly block the possibility of getting to your site's management area if your'e not in a specific place or using the right VPN connection.

Iron Curtain

Developed by Reload, sponsored by Scribo.

This module allows the site admins to restrict access to certain paths or the entire site, based on the visitor's IP address.

It allows users with a certain role to bypass the system, it allows a list of paths to bypass the system and it allows you to make a list of paths which can only be seen by whitelisted IPs, and another list which can not be accessed by blacklisted IPs.

Maths Captcha

Screenshot showing maths captcha in action.

This adds a simple maths-based question (e.g. what is 5 plus 8?) to selected forms to help test whether the user is human or not.

Users with appropriate permission can specify a list of form ids to protect, which can include wildcards like foo*

The question is inserted before the first submit element, or at the end if a submit element cannot be found at the time hook_form_alter() is called.

It is a stateless mechanism, so no session variables/cookies are required. There is a 15 minute timeout from generation to validation.

Ban By Referer

Ban by Referer allows you to create blacklist for referrers.
