Fail2ban filters to protect NginX

Each filter has 2 parts:

• a configuration part that is in /etc/fail2ban/nginx.conf
• a definition part that is in a file in /etc/fail2ban/filter.d/.conf

To configure:

1. Copy the filter files

sudo cp nginx-*.conf /etc/fail2ban/filter.d/

2. Copy the jail configuration file

sudo cp nginx.conf /etc/fail2ban/jail.d/
