streamlined. Though, the members of the federation must have a
way to trust one another to make it work effectively.

Web Portals
Web portals act as a front end to many services behind the
portal. An organization, such as a bank or government, provides
many different types of services to its clients/citizens. Instead of
having different web pages that a client must separately go to for
each individual service, the bank sets up a front end page that
acts as the entrance or lobby for the clients.

From that page, they can log in, and they can select various
services. Through the use of cookies, their preferences can be
"remembered" so that the web page is configured according to
their preferences on future visits. Whereas a federated system
links different companies together, a web portal is often linking
various services of one company together.

Script-based Sign-on

When an individual logs on to an information system, the
system executes a logon script that requests the login ID and
password from the user. Originally every system was built with
its own login script, and the user was required to log in
separately to each system. The script-based single sign-on
system puts a front end application in front of the older legacy
systems that the user logs into. Then the application executes the
scripts in the background to allow the user to log into each of the
individual systems "hidden" behind the single sign-on
application.
