Prevent brute force attacks using fail2ban
fail2ban monitors log files such as /var/log/auth.log and /var/log/apache/access.log and temporarily or persistently bans failure-prone addresses by updating existing firewall rules. Currently, by default, fail2ban supports ssh/apache/vsftpd but configuration can be easily extended for monitoring any other ASCII file.
1. Install fail2ban
apt-get install fail2ban
