This extension bans IP-addresses, which are bruteforcing your Pagekit-based installation. It also allows you to ban IP-addresses, which are attempting to visit pages they don't have the correct permissions to ("forbidden-jail").
I also inserted a little honeypot, as I mentioned a lot of IP-addresses trying to open
wp-login.php on some of my Pagekit-based projects.
Using the honeypots you are free to specify any string you want: If the URL the attacker attempts to open contains the specified string, the IP is being logged.
For large traffic sites there's a little "spam-jail": If you are marking a comment as spam, the IP is added to the jail.
But don't worry: You are free to enable or disable every jail - you are also able to configure the number of attempts before an IP is banned.
I hope you like this extension. I am going to add new features soon.
