This script, when properly installed, will log and track any failed authentication attempts for your members area(s). When the failed number of attempts coming from one certain IP exceeds a limit you set, the script will automatically block that IP from accessing your entire site. This will also effectively block any person trying to brute-force their way into your members area(s). Whenever a block is placed, you will be notified by e-mail so you can take the appropriate action, e.g. contact the offenders ISP. The blocking system is totally automated, provided you have set up the correct .htaccess entries.
