## Fail2Ban: ban hosts that cause multiple authentication errors
Fail2Ban scans log files like /var/log/pwdfail and bans IP that makes too many
password failures. It updates firewall rules to reject the IP address. These
rules can be defined by the user. Fail2Ban can read multiple log files such as
sshd or Apache web server ones.
Fail2Ban scans log files like `/var/log/auth.log` and bans IP addresses
having 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 easy to configure to read any log file you choose, for
any error you choose.
Fail2Ban is able to reduce the rate of incorrect authentications attempts
however it cannot eliminate the risk that weak authentication presents.

Configure services to use only two factor or public/private authentication
mechanisms if you really want to protect services.
