Adding a non-root user on BackTrack 5R1

After installation of BackTrack 5 R1, there is only one user: root (or superuser). Root has full privileges in the operating system, and that makes our system more vulnerable to external attacks. A superuser can manage other user’s account, administer user data, install new applications, and configure system services and others. And of course, we can be that attacker if and when we mess up.

When installing on a hard disk and also using the system for some research and communication on occasion, we best create a non-root user with limited privileges and use su and sudo when we need more.
