Ubuntu’s goal is to be secure “out-of-the box”. By default, the user’s programs run with low privileges and cannot corrupt the operating system or other users’ files. For increased security, the sudo tool is used to assign temporary privileges for performing administrative tasks, which allows the root account to remain locked and helps prevent inexperienced users from inadvertently making catastrophic system changes or opening security holes.
