Root user definition

Root user refers to a special user account that has the highest level of privileges and authority within the system, granting unrestricted access to all files, directories, commands, and system resources. Root user is a term used in Unix-like operating systems such as macOS, Linux, and Unix, while in Windows this type of access is known as a superuser or an administrator.

As root users can bypass security restrictions and permission settings, this level of access can also cause potential risks when used by inexperienced users.

Root user access considerations

Users with root access can accidentally damage the system and open it up to attacks. That’s why it’s important to consider ways to avoid root access misuse. For example, organizations should be implementing strong authentication mechanisms and logging root-level activities.
