Single Sign On
Single sign-on (SSO)is a user authentication process that permits a user to enter
one user id and password in order to access multiple applications. The process authenticates
the user for all the applications they have been given rights to and eliminates
further prompts when they switch applications during a particular session.
Single sign on gives ability to enforce uniform enterprise authentication and/or
authorization policies across the enterprise with end to end user audit sessions
to improve security reporting and auditing.It removes application developers from
having to understand and implement identity security in their applications.
Single sign on can also take place between enterprises using federate authentication.
Single sign on systems in medium to large enterprises can become a single point
of enterprise.If the single sign on system goes down but the applications remain
up, no user can access any resource or application protected by the SSO system.Therefore,
it is essential that our enterprise single sign on system have a good and well tested
failover and disaster recovery design.
