D.5 WEB Users Setup and Configurations Controls Options
We use authentication and authorization together with a user database and a Security
Realm to design a secure site. This makes use of users and groups, where users are
generally people that may access the system, and groups represent the position that
users can hold.
The web user database consists of three users, with initial default names of guest, oper,
and admin. Access rights and authentication make it possible to restrict/control access
to a specified set of web users. Any of the three user names can be modified. The user name
can have up to 14 characters supporting alpha and numeric characters. Alpha characters can be
entered using the up and down arrow keys. Numeric characters can be selected by using the
number keys.
