### More protections measures with fail2ban ### More protections measures with fail2ban
If you are running fail2ban to protect your system, you can also add a filter and jail for authelia to reduce load on the application / web server from repeated hacking attempts. If you are running fail2ban, adding a filter and jail for Authelia can reduce load on the application / web server. Fail2ban will ban IPs exceeding a threshold of repeated failed logins at the firewall level of your host.
If you are using docker, the Authelia log file location has to be mounted from the host system to the container for fail2ban to work. Otherwise fail2ban is unable to access it. If you are using Docker, the Authelia log file location has to be mounted from the host system to the container for fail2ban to access it.

Modify the `jail.local` file. In Debian-based systems the folder is typically located at `/etc/fail2ban/`. If the file does not exist, create it by copying the jail.conf `cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local`.

Finally, restart the fail2ban service.
