+	  Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs
+	  that show the malicious signs -- too many password failures, seeking
+	  for exploits, etc. Out of the box Fail2Ban comes with filters for
+	  various services (apache, courier, ssh, etc).
+
+	  Fail2Ban is able to reduce the rate of incorrect authentications
+	  attempts however it cannot eliminate the risk that weak authentication
+	  presents.
