Fail2Ban Documentation

Craft's security events, in a form your firewall can act on

Installation

Requirements, install, handing the generated files to fail2ban, and proving it works before you need it to.

Channels, which events are on, client addresses and proxies, blocked usernames, jails, the built-in blocker and permissions.

Every event and the line it writes, raising your own events from Twig or PHP, the control panel screens and the console commands.

What to check when nothing is logged, nothing is banned, the wrong address is banned, or you have locked yourself out.

The questions worth answering before installing it.
