Login lockdown is a plugin I only installed recently after considering the security of my blog because of a recent attack by hackers on all the wordpress blogs that had not updated to the latest stable and available version of wordpress.
The plugin effectively adds a barrier or security gate to the administration login page which helps protect against automated attacks from robots or malicious scripts who attempt to take control of your blog by a method of “brute force” password discovery. Basically they hammer the login panel with an automatic system until they accidentally discover your login details.
Once the plugin is simple to active, and can be configured to suit your needs quite easily. Don’t be the one who gets caught out, protect yourself!
