Would closing CPanel ports (2082,2083,2086,2087) through APF help with security? :)

Sure :D

But it might make getting into cPanel/WHM difficult ;)

Is there a better way to prevent hackers from entering Cpanel/WHM?

A> Don't use APF, use CSF, which will ban individuals who have made XX number of invalid logins from accessing your server period. While APF/BFD does this (somewhat), it's not as well put together as CSF is in this regardes

B> Use hosts.allow and hosts.deny. Lock off EVERYTHING from accessing 2086/2087 in hosts.deny then ALLOW your ip address in hosts.allow . You'll have to look up the manual for doing this yourself, as it can be tricky, and I am not 100% sure that cp still supports this protocol.

Those are two of the best ways to prevent individuals from trying to 'break in" to WHM/CP

As you can tell I'm kinda new at this, but...

Hypothetically, couldn't they learn my IP, spoof it, and hack away...? :confused:

I'll try your first option... Thanks... :agree:

Well what if you have a dynamic IP. Also there is always packet sniffing which you cannot stop.

The only way that I've seen malicious access gained is through weak passwords. Make sure that your clients passwords are strong. To make sure your password are beefy, I recommend:

Editing /etc/login.defs to configure many password options on your system. It is well documented. You can set minimum length, etc.

If you are not sure of how secure a password is, you can test it using JTR crack. If a password can be broken in a few hours, it is probably too insecure and should not be used. You can also install tools like pam_passwdqc to check the strength of passwords.

I won't do that for sure :blush:

Anyways, if you are concern about the security of your server, why don't you check out some tutorials at:

Alternatively, there are sysadmins like rack911.com, sprintserve.net, seeksadmin.com, serversupportguys.com... etc whom you can pay a small fee for them to secure your server for you :)

Good luck!
