BFD stands for Brute Force Detection and is an SSH script you can use to parse applicable logs to check for authentication failure. Basically, BFD adds another layer of security to your dedicated server, ensuring that you will be aware of any brute force attacks that try to take down your machine.
BFD works in conjunction with APF Firewall and is very straightforward in its installation and configuration, like most Linux server tools.
