After reading about a few WordPress Blogs getting hacked, I am finding that I have started reading more about the Online Security aspects, and probably a few of my last posts reflect that as well. Recently I have come across a really nice WordPress Plugin, which is a great tool to restrict unauthorized access to your WordPress Blog.
Welcome to Login LockDown WordPress Plugin.
It records the IP address and timestamp of every attempt which results in failure to login to your WordPress Account. If it is seen that the a particular IP is repeatedly attempting and failing to login to your account then the login function is disabled for all requests from that range. This foils the attempt to break your password simple by trial and error methods.
Currently the plugin defaults to a 1 hour lock out of an IP block after 3 failed login attempts within 5 minutes. This can be modified via the Options panel. Administrators can release locked out IP ranges manually from the panel.
They have recently released the version 1.2 of the plugin, which is compatible with WordPress 2.5.1 also.
