fail2ban is log based brute force blocker. Fail2ban will monitor the system log files and when certain configured events occur they will trigger fail2ban to block the offending host.
I have been using fail2ban to stop the flood of attacks via my ssh port. Together with setting /etc/hosts.deny to "ALL: ALL" and /etc/hosts.allow to "sshd: SPECIFIC_IP_ADDRESSES", I also change the port number in /etc/ssh/sshd_config to something other than "Port 22". It works well.
