An anti-spam solution that limits the amount of handshakes per second and per attempts with the option to permanently ban the attack IP.
If the attacker tries to spam your server with 10 packet requests in less than 1 second, the server will block the attacker’s connection for at least 10 minutes (adjustable), after waiting (cooldown), the attacker can again establish a connection (handshake) to the server.
