Which two statements is true relating to authentication in Oracle Application Express?
A.
It is a process of establishing user identity before the user can access an application.
B.
An authentication scheme can be specified for an entire application, page, or specific
components
Such as item, button and regions on a page.
C.
An authentication scheme prevents a user from accessing session state belonging to other
users.
D.
An authentication scheme helps a user to reestablish their session when they log back into an
application allowing them to bookmark the application.
E.
An authentication scheme can only be applied to one application.
Explanation:
A: Authentication establishes the identity of each user who accesses your
application.
Authentication is the process of establishing each user’s identify before they can access your
application. Authentication may require a user identify a user name and password or could involve
the use of digital certificates or a secure key.
C: When running custom authentication, Oracle Application Express attempts to prevent two
improper situations:
* Intentional attempts by a user to access session state belonging to someone else. However,
users can still type in an arbitrary application session ID into the URL.
* Inadvertent access to a stale session state (probably belonging to the same user from an earlier
time). This would commonly result from using bookmarks to application pages.
