WordPress Simple Login Lockdown

. November 30, 2011 . 0 Comments

Simple Login Lockdown plugin by chrisguitarguy prevents brute force login attacks/attempts on your WordPress installation.

How it works: 1. An attacker attempts to login and fails 2. Simple Login Lockdown record that failed login 3. After a certain number of failed attemps (defaults to five), further attemps to access the wp-login.php page are blocked for a time (defaults to one hour).

If you happen to forget your password and make a failed login attemp yourself, the plugin will clear out the lockdown count data on successful login.

Author Note: This uses $_SERVER[‘REMOTE_ADDR’] directly. If you’re behind a proxy (load balancer, etc), it’s not going to work as expected. Eg. Several folks could be attempting logins at once, and all fail. As such, the plugin would pick up on all those requests coming from the same IP — the load balancer — and lock the login down. No good. If you’re using a load balancer or in some other situation where you’re behind a proxy, use this as an example and write your own. Or filter the IP as your desire using cd_sll_pre_ip.
