+	  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.
