+addresses conducting too many failed login attempts.  It does this by updating
+system firewall rules to reject new connections from those IP addresses, for
+a configurable amount of time.  Fail2Ban comes out-of-the-box ready to read
+many standard log files, such as those for sshd and Apache, and is easily
+configured to read any log file of your choosing, for any error you wish.
+
+Though Fail2Ban is able to reduce the rate of incorrect authentication
+attempts, it cannot eliminate the risk presented by weak authentication.  Set
+up services to use only two factor, or public/private authentication
+mechanisms if you really want to protect services.")
