As you know, if you manage a dedicated server you only should provide ssh access to people you trust, so is recomended to disable shell access on all cPanel accounts. The problem is that when you create a resseller acount the owner of this account can give shell access. How to stop it?

Go to Feature Limits for resellers in Resellers
=> Reseller Center,
=> Under "Privileges" always disable "Allow Creation of Packages with Shell Access"
=> Enable "Never allow creation of accounts with shell access"
=> Under Root Access disable "All Features".

It will increase your server security level.

After it, goto "Account Functions" => "Manage Shell Access"
=> "Disable Shell Access for all users" (except you login)
