fail2ban App For Raspberry Pi

This video demonstrates the fail2ban application that monitors your system logs for the various servers running on the Raspberry Pi. In my case, I have three jails: sshd, apache2, and ssh-ddos that ban individuals who attempt to log into my servers and the login fails three times in 10 minutes. These individuals get banned for 24 hours and hopefully go away.
