The IAG 2007 provides a means to create an access portal to corporate network
applications, accessible by a Web browser, which allows end users to authenticate their
credentials and access only those applications and features that their administrators??™ defi ned
policies allow. IAG 2007 supports an unlimited number of users, and up to 64 IAG nodes
can be combined in a high-availability confi guration, thus meeting corporate needs.
Access to corporate applications is assisted through the use of specialized ???application
optimizers,??? which are available from several Microsoft and third-party software offerings,
including Microsoft Exchange server and Microsoft SharePoint portal server. These
application optimizers consist of integrated software modules with preconfi gured settings
designed to allow access to the target applications through the IAG portal. Features
provided by the optimizers to the target applications include single-sign-on support with

the ability to apply certain granular rights assignments per user policy, and support for
???attachment wiper,??? which removes and scrubs temporary session data from the client,
including browser history fi les and pages, auto complete form contents, temp fi les,
cookies, history, browser closure, and system shutdowns such as logoff and browser failure.
Last but not least, the optimizers also even blocking fi le uploads if an approved
virus scanner is not present on the endpoint machine.
