fail2ban

This service is provided by SWAG by default  it is used to automatically ban someone trying to access your server and using invalid authentication.  It does this by banning the IP address of the attacker for an increasing amount of time for each offense.

Fail2ban works out of the box with intrusion detection for basic http authentication as well as Authelia.  For other applications that do not use these, such as Plex, Jellyfin, and other apps that have their own login screen, you will need to manually configure them. Fail2ban works with these services by monitoring their log files for evidence that someone failed to login.
