To enable cPHulk , you need to login in whm control panel as root. From the main menu on the left, click on Security Center from the Security section.
Click on the cPHulk Brute Force Detection link at the top of the page. Now you may want to configure cPHulk before you enable it. The configuration parameters are pretty much self-explanatory so I won’t go into details about this. Basically you set the number of failed attempts before an IP or an account is blocked and you set how long you want it to be blocked.
When you’re done, just click on the Enable button at the top.
