Access Rights and Authority Levels are the rights or power granted to users to create, change, delete or view data and files within a system or network. These rights vary from user to user, and can range from anonymous login (Guest) privileges to Superuser (root) privileges. Guest and Superuser accounts are the two extremes, as individual access rights can be denied or granted to each user. Usually, only the system administrator (a.k.a. the Superuser) has the ability to grant or deny these rights.
