VPS or Dedicated Hosting - cPHulk Brute Force Protection

Overview

This article will cover the use of cPHulk. cPhulk is software designed to protect your server from brute force login attempts. It does this through blacklisting IP addresses that have too many failed login attempts within a short period.

ATTENTION: When enabling cPHulk it is critical that you whitelist your own IP address so that you do not block yourself from your server. If you believe you have been blocked from your server please refer to the Whitelisting in cPanel section.

Note: If you need your IP address, it can be found at www.HostMonster.com/ip
