Every system administrator will have fear that the server should not be hacked. For example, If there is domain called example.com then the hackers may try to login with the user name as example and enter random passwords like example@123 etc.
To block anonymous user/IP
The system administrator can block the anonymous user by registering and licensing with cPanel.
The cPanel provides various options to block anonymous IP using the Brute Force Protection. If particular user is trying to access or login with bad user name and password, it waits for 5 attempts. For security reasons the system will temporarily block the IP address to prevent the further attempts and sends the mail notification of the specific IP address to the registered mail id.
The mail received has the information' s like remote IP address, Number of authentication failure, maximum number allowed etc.
To blacklist the IP address
Navigate to the cPanel page&rarr security center &rarr cPHulk Brute Force Protection &rarr click blacklist management.
cPHulk provides the protection from brute force attacks against web services.
Now add the anonymous IP address in the new blacklist records and click add as shown in the below image.
