"The root user account is created by the operating system when it is installed. This user is the superuser who basically has complete control of the entire system. This means that great care should be taken to preserve the integrity of this account. One aspect of this care is to ensure that the root password is complex and changed on a regular basis. In addition, the root account should not be used to log into a server because if anyone gains access to the root account they have complete control of all services and information located on the server."
