Enabling cPHulk on your Dedicated Server

Your server may be open and exposed to the whole Internet, through which many people can access your services like WHM, cPanel, email accounts, and FTP. Brute Force Attack is unauthorized attacks that access all the services through various automatic login attempts with huge possibility as the attacker has a hope of guessing the correct combination to gain access.

The cPHulk Brute Force Attack is given by cPanel and you are allowed to work with the level of Pluggable Authentication Module (PAL) for detecting the failed login attempts in the IP address. When a failed login attempts reaches the number that has been already set, the further failed login attempts are blocked by the cPHulk. At the PAL level, cPHulk protects the server by blocking the IP address. It is safe to blacklist the whole set of IP address (For instance Specific Country). You did not worry that the users from the countries cannot access your services. The access will be denied if they try to login one of these cPanel Core Services.
