This is a text description of asoag005.gif, an image which depicts how authentication adapters integrate below the Oracle Net interface. This allows existing applications to take advantage of new authentication systems transparently, without any changes to the application. The Oracle Net layer, which contains Oracle Advanced Security is shown in the image. Various Oracle and non-Oracle software applications are layered on top of Oracle Net, including Oracle Forms, Oracle Reports, third-party tools, 3GL tools, Oracle servers, and Oracle Call Interface. To show that the Oracle Advanced Security authentication adapters reside below the Oracle Net layer, the following authentication adapters are shown hanging off the Oracle Advanced Security section of the Oracle Net network layer: Kerberos adapter, SSL adapter, DCE (Distributed Computing Environment) adapter, and the RADIUS adapter.
