Originally built off the WordPress Firewall 2, it now includes much more:
Basic functionality is based on the principles employed by the WordPress Firewall 2 plugin.
Note: Login Protection is a completely independent feature to the Firewall.
With the Login Protection features this plugin will single-handedly prevent brute force login attacks on all your WordPress sites.
It doesn't need IP Address Ban Lists (which are actually useless anyway), and instead puts hard limits on your WordPress site, and force users to verify themselves when they login.
Three core security features provide layers to protect the WordPress Login system.
These options alone will protect and secure your WordPress sites from nearly all forms of Brute Force login attacks.
And you hardly need to configure anything! Simply check the options to turn them on, set a cooldown interval and you're instantly protected.
As of version 1.6, this plugin integrates GASP Spambot Protection.
We have taken this functionality a level further and added the concept of unique, per-page visit, Comment Tokens.
Comment Tokens are unique keys that are created every time a page loads and they are uniquely generated based on 3 factors:
This is all handle automatically and your users will not be affected - they'll still just have a checkbox like the original GASP plugin.
These comment tokens are then embedded in the comment form and must be presented to your WordPress site when a comment is posted. The plugin will then examine the token, the IP address from which the comment is coming, and page upon which the comment is being posted. They must all match before the comment is accepted.
Furthermore, we place a cooldown (i.e. you must wait X seconds before you can post using that token) and an expiration on these comment tokens. The reasons for this are:
This all combines to make it much more difficult for spambots (and also human spammers as they have to now wait) to work their dirty magic :)
