For those of you with a dedicated web server (or a VPS Hosting), I would like to recommend a great firewall application which is extremely good at securing your server.

The firewall module can block out users for failed FTP login attempts, failed SMTP/POP login attempts, and failed cPanel login attempts. There is also an option to ban those users to trigger mod_security

The greatest thing is that it is extremly easy to install!

Please see the relevant blog article on how to install CSF and LFD:

CSF can also issue a security report for your server, showing you how secure your server is, and how to secure any potential vulnerabilities.

I hope this helps!
