This simple module adds a CKEditor filter that allows you to check the access permission for the links inside the editor for which the current user does not have access to them.
Basic perimeter defence for a Drupal site. This module bans the IPs who send suspicious requests to the site. The concept is: if you have no business here, go away.
Use the perimeter module if you get a lot of requests to 'wp-admin' or to .aspx urls on a Linux server, or other similar requests. The URL patterns that result in a ban can be configured in the admin settings
